Guava is also known as the “Apple of the Tropics”. It is very rich and cheap source of vitamin C and also contains a fair amount of calcium. Important guava growing states in the country are Uttar Pradesh, Bihar, Madhya Pradesh and Maharashtra. Allahabad district of Uttar Pradesh has the reputation of growing the best quality of guava fruits in the world (Mitra and Bose, 1990). The importance of guava is due to the fact that it is the hardy fruit which can be grown in alkaline and poorly drained soil.

1. Introduction
Aquaculture has become one of the most significant contributors to global food production, responding to the escalating demand for fish and seafood. As a rapidly growing industry, aquaculture plays a crucial role in ensuring food security, nutrition, and livelihoods. According to the Food and Agriculture Organization (FAO), aquaculture production has expanded at an average annual rate of 5.3% over the past 30 years. This growth has positioned aquaculture as a primary source of protein, essential fatty acids, and micronutrients for billions of people worldwide. Despite its rapid expansion, the aquaculture industry faces significant environmental challenges, primarily due to the large amounts of organic waste generated by fish farming. This waste includes uneaten feed, fish excreta, and the remnants of dead organisms, all of which can contribute to nutrient pollution when not properly managed. Nutrient pollution is associated with serious ecological consequences such as eutrophication, where excess nutrients lead to algal blooms, oxygen depletion, and the degradation of aquatic habitats. These environmental issues threaten biodiversity and undermine the sustainability of aquaculture systems.
Nutrient recycling has emerged as an innovative and sustainable solution to address these challenges. This approach transforms waste into valuable resources, particularly in the form of nutrient-rich feed ingredients. By harnessing nutrients such as nitrogen, phosphorus, and organic matter from aquaculture waste, nutrient recycling not only reduces environmental impact but also improves the economic efficiency of aquaculture operations. Nutrient recycling promotes a circular economy model, where waste from fish farming is reintroduced into the system, closing nutrient loops and reducing the reliance on external inputs.

Human migration is the movement of people from one area to another with intentions of settling, permanently or temporarily, at a new site (geographic region). The movement frequently happens across great distances and from one nation to another, although internal migration (inside a single country) is also feasible; fact, this is the major type of human migration worldwide. Migration is typically connected with stronger human capital at both individual and household level, and with better access to migration networks. Age is also essential for both job and non-work migration. People may travel as individuals, in family groupings or in big groups. There are four primary modes of migration: invasion, conquest, colonization and immigration/ emigration (Daylit et al., 2022).
Individuals migrating from their home owing to forced displacement (such as a natural catastrophe or civil conflict) may be classified as displaced individuals or, if staying in the home nation, internally-displaced persons. A person who seeks shelter in another nation may, if the reason for leaving the home country is political, religious, or another type of persecution, submit a formal application to that country where protection is sought and is then commonly characterized as an asylum seeker. If this application is successful this person’s legal status becomes that of a refugee.
In modern times, migration governance has grown strongly tied with state sovereignty. States maintain the right of deciding on the admission and stay of nonnationals since migration directly impacts some of the distinguishing qualities of a State (Mawire et al., 2020).

Blood transfusion is one of the crucial life-saving procedures in veterinary medicine undertaken to increase red cell mass, volume replacement, replenishing coagulation factors, and protein replacement. The concept of blood transfusion was first introduced by Francis Potter in 1639. However, it was only in 1666 that Richard Lower reported the first successful direct transfusion from one dog to another. Blood is a biological drug and is not a definitive treatment, but it provides support until the disease is diagnosed or treatment is initiated. Indications Blood transfusion is indicated for the management of the following conditions: •     Anemia due to various diseases/disorders, like infection or acute/ chronic hemorrhage •     Bleeding disorders such as thrombocytopenia or coagulopathies •     Rodenticide toxicities

Rice-wheat (RW) is the major cropping system occupying about 10.5 mha in the IGP of India. It contributes more than 60% of the foodgrains to the central pool. With shrinking land resources and burgeoning population, the RW system will be under pressure to produce more grain output per unit area in the coming decades. Meeting this challenging task requires sustainable management of soil, water and plant nutrient resources. High yields of the irrigated RW system result in production of huge quantities of crop residues. Total production of crop residues in Punjab is about 47.2 mt which includes paddy straw, wheat straw, cotton sticks, sugarcane leaves, maize stalk, and other oilseeds and pulse residues (Beri and Gupta, 2003). Wheat and rice straw constitutes more than 70% ofthe crop residues produced in the country. Paddy straw alone constitutes more than 50%. Cotton and sunflower residues are generally used as fuel. Sugarcane trash (leaves) is generally burnt in-situ or used as fuel after collection from the field. Increasing constraints of labour and time have led to the adoption ofmechanized farming in the highly intensive RW cropping system. Approximately 91% ofthe total rice area is mechanically harvested, while 82% of the total wheat area is mechanically harvested. Traditionally, wheat and paddy straws have been removed from the fields for use as cattle feed and for several other purposes such as livestock bedding, thatching material , for houses, and fuel. While more than 80% ofwheat residue is collected by the farmers after combine harvesting and often fed to animals, paddy straw is considered poor feed for animals due to its high silica content.

Substantial loss ofplant nutrients (especially N and S) and organic carbon occurs during burning of crop residues, with important implications to soil health. About 40% of the N, 60-85% of the K, 30-35% of the P, and 40-50% of the S absorbed by rice remains in the vegetative parts at maturity. One tonne of paddy straw contains approximately 6-7 kg of N, 1.0-1.7 kg of P₂O₅ and 14-25 kg K₂O. Apart from huge loss of precious plant nutrients, burning of crop residues depletes soil health. Air pollution from stubble burning also impacts human and animal health both medically, and by traumatic road accidents due to restricted visibility. In view ofthe serious problems associated with the residue burning, new ways are being sought to efficiently utilize the huge amount of surplus residues produced in the country.

Ber (chinese date, chinese fig or bore) is an important minor fruit of India. It is hardy fruit tree cultivated all over India and also known as poor man’s fruit. It is most widely cultivated in Punjab, Haryana, Rajasthan, Uttar Pardesh, Madhya Pradesh, Bihar, Gujarat, Maharashtra etc. Ber can do well even under marginal growing conditions and provides quality yields at low cost (Shukla, 1996). Fruits are mostly eaten fresh but the other forms, such as dried, candied, squash etc can also be prepared from ber. Stem bark, root and leaves have some medicinal values. Leaves of ber are used as fodder in dry regions. Ber tree (Ziziphus xylopyrus) is a host plant for rearing the Tachardia laccad a lac insect (Sharma and Kore, 1990).

Food Contact Materials (FCM)

Before food consumption, during production, processing, preparation, packaging, packing, transportation, storage, serving etc. food comes in contact o many materials, all these materials are called food contact materials (FCM). FCM may be containers used for transportation for example milk container, machineries for its production or processing, packaging materials for its packaging like cans of soft drinks, kitchenware used for its cooking, serving, heating, washing. The selection of FCM requires intense care because FCM can affect human health and also the quality of food. During contact with food, molecules can migrate from FCM to food. Hence, FCM should have the following common attributes:

1. FCM should be compatible with the materials used for production, processing, transport, storage, serving etc.

2. FCM should be inert and non-reactive.

3. FCM should withstand the chemical, Mechanical and Thermal variations.

4. FCM should be clean, hygienic and tamper proof.

5. FCM should not have blisters, cracks, sharp edges and visible defects. 6. FCM should be free from rust.

India ranks first in goat population with 148.88 million goats and 10.14% growth rate (DADF, 2019). Goat meat contributes around 37% of the total meat produced from the livestock sector in India which comes from the 42% of goat population annually (GOI, 2019). Goat has served as source of livelihood support and financial security to large section of society, especially to the resource-poor farmers. However, in the current scenario, this small ruminant farm animal has tremendous potential to be projected as the “Future Animal” for rural and urban prosperity. Rapid transformation of backyard goat farming to “commercial goat industry” is taking place in the country. The perception of goat as “poor man’s cow” to “preferred livestock species” is fast changing; therefore, to meet this transformation goat rearing system is shifting gradually from extensive low input system for livelihood purposes to semi- intensive and intensive rearing system for commercial purposes in India (Ramachandran et al., 2019). Due to their higher resilience capacity to climate change and better adaptability goats play significant role in ensuring food security. Goats have traditionally been a significant asset and source of protein for rural communities inhabiting arid and semiarid regions of the world. It is an endeavour of millions of small holders who rear animals on crop residues and Common Property Resources. The small holders produce milk, meat, fibre, skin etc for the community with virtually less capital investment, resources and formal training. They are conventionally raised on grazing resources. However, these resources are gradually shrinking over the periods both in terms of quality and quantity. On the other hand, there is continuous rise in the demand of meat which led to further deterioration of available grazing resources.

Sensory evaluation is a scientific method of evaluating foods including meat products that applies principles of experimental design and statistical analysis through the use of human senses like sight, smell, taste, touch and hearing. It is also called organoleptic evaluation in which we measure, analyse and interpret reactions to those characteristics of materials as they are perceived by the human senses. These attributes can be perceived well by the human sense organs as compared to instruments available for this purpose. It is a fact that no single instrument is able to assess all the attributes of meat products. With the help of these instruments we can very well evaluate the single quality attribute of meat product i.e. shear force instrument or penetrometer is good for knowing the texture and refractometer is for colour interpretation.

INTRODUCTION

A parasite is an organism which exploits another organism for the purpose of staying alive. Some parasitic relationships are harmless, while in other cases a parasite can damage or even kill its host. The word is borrowed from the Greek word ‘‘parasitos’’, meaning “one who eats at the table of someone else.” In case of exotic carps parasites causes a great loss by reducing economy. Some, cannot live once their host dies, while others can continue thriving on dead hosts until their nutrients are consumed. Parasites live inside a host are called endoparasites or internal parasites. Ectoparasites live outside the host, and are generally more capable of switching hosts. A parasite preys on other parasites, is called epiparasite (Anderson, 1974).

Silver Carp

The silver carp (Hypophthalmichthys molitrix) is a species of freshwater cyprinid fish, a variety of Asian carp native to north and northeast Asia. It is cultivated in China. Pound for pound, more silver carp are produced worldwide in aquaculture than any other species. Silver carp are usually farmed in polyculture with other Asian major carps, or sometimes Indian major carps or other species. It has been introduced to, or spread into via connected waterways, at least 88 countries around the world.Introduced in india in 1959 at the pond culture division of CIFRI. In India in 1963 breed sucessfully by hypophysation. The silver carp is a filter feeder, and possesses a remarkably specialized filtration apparatus capable of filtering particles as small as 4 µm. The gill rakers are fused into a sponge-like filter, and an epibranchial organ secretes mucus which assists in trapping small particles. A strong buccal pump forces water through this filter. Silver carp, like all Hypophthalmichthys species, have no stomachs; they are thought to feed more or less constantly. Silver carp are thought to feed largely on phytoplankton; they also consume zooplankton and detritus. It is used in controlling water quality, especially control of noxious cyanobacteria (blue-green algae), microcystis .

Strain Selection and Improvement

In biofertilizer technology, strain selection occupies the foremost criteria, so as to explore its biological potentialities for the beneficiary crop. The selected strain used in biofertilizer production must be efficient to grow fast besides retain desirable potentialities of biological activities, which should be present in desired high numbers and must be stable. The strain must be improved periodically so as to sustain the productivity.

It involves a systematic approach to assess the progress performance, and effectiveness of strategic objectives and make necessary adjustments to ensure alignment with organizational goals. Here are some key points on the introduction to the strategic control process. Strategic control refers to the ongoing monitoring, evaluation, and adjustment of an organization's strategic activities to ensure they are in line with the desired outcomes and objectives. It The significance of strategic control lies in several key reasons. helps organizations track their progress, identify deviations from the intended course, and take corrective actions. It also enables managers to assess the effectiveness of strategies, make informed decisions, and enhance organizational performance.

1. Introduction

Milk is the principal source of protein and lactose in the diet. Dairy farming is viewed as a whole ecosystem of reciprocal relationships and reliance, as well as there production and safe guarding of societal values. Dairy farms are primarily made up of high-yielding dairy cows. Goats, sheep, and camels are some of the other animals employed in commercial dairy production. Milk has always been regarded as a healthy food. Milk includes more than9 other essential elements, including protein, carbs,vitamins, minerals, and lipids, in addition to calcium, which makes it critical for your bones.

Every year, about 600 million tonnes of milk are produced by over 264million dairy cows across the world. The global average for milk output per cow is around 2,200 litres. India is the world’s top milk producer followed by the United States, China,Pakistan, and Brazil. The economy of India is mostly dependent on agriculture and animal husbandry, with milk production playing a significant role. It is also the world’s largest producer of buffalo milk (FAO, 2019).

Co-operative dairy sector proved to be resilient as it continued to procuremilk from farmers and supply it to the consumers despite several logistical and other challenges. Milk production in India did not show any sign of slowdown. Milk productionis anticipated to be around 209.96 million tonnes in 2020-21, an increase of about 6.3 percent over the previous year. The estimated per capita availability of milk is expected to increase to about 425 gms /day which is more than the world average of around 315gms/day(NDDB,2020).The dairy co-operatives had a difficult year due to an influx of more milk production, a reduction in milk sales, and the building of inventories of preserved goods. Throughout the year, milk procurement by dairy co-operatives increased as it accepted diverted extra milk from farmers that would otherwise be sold to private and unorganized businesses. During the 2020-21 budget year, milk procurement by dairy co-operativesincreased by 7.9 per cent. Indian dairy co operatives have installed milk processing capacity of 66.3million litters per day,73.3million liters/day in private sector enterprises, and 2.5 million litres per day in producer companies.

1. Introduction
Reproduction is one of the most critical processes in the life cycle of fish, directly influencing population sustainability, species survival, and aquaculture productivity. Successful reproduction hinges on several interconnected factors, including environmental conditions (such as water quality, temperature, and photoperiod), genetic predisposition, physiological health, and, most importantly, nutrition. Among these, nutrition has a profound and direct influence on reproductive performance in both wild and cultured fish populations.
In aquaculture, the reproductive success of broodstock—mature fish that produce offspring—is paramount to the production of high-quality fry (young fish) and larvae, which in turn affects the overall yield and profitability of fish farms. Ensuring that broodstock are provided with an optimal diet tailored to their reproductive needs can significantly enhance fecundity (the number of eggs produced), fertilization rates, and the viability of offspring. Proper nutrition not only contributes to better gamete (egg and sperm) quality but also plays a vital role in boosting the health, vitality, and resilience of both broodstock and their progeny.
Nutritional deficiencies or imbalances during the reproductive phase can lead to a variety of problems, such as reduced spawning frequency, poor egg and sperm quality, low hatching rates, and poor larval survival. Conversely, well-nourished broodstock with access to essential nutrients are more likely to produce high-quality eggs and sperm that result in healthier, more viable offspring.

A literature review is an organized, in-depth examination of books, journals, and research papers related to a particular subject that serves as a foundation of knowledge. By pointing out gaps in the present body of knowledge, literature reviews aim to identify and evaluate the body of existing research on a certain subject in order to support your own study. This inquiry needs to include an explanation, synopsis, and critical assessment of previous studies pertaining to the research challenge. It should also contribute to the body of knowledge on the subject and show how your findings will fit into a broader body of knowledge. Your research goal should be guided by the critical examination of the most recent research on the subject provided by a literature review. This is not the same as a book review or an annotated bibliography, which are research instruments with quite distinct goals and purposes. Writing a process document is essential to a successful literature review.
Purpose
A literature review’s objectives are to:
• Offer a solid foundation of information on the subject.
• Locate areas of earlier study to avoid repetition and to acknowledge the contributions of other experts.
• Determine the need for further research (include evidence to support your findings).
• Determine how one piece relates to the other and to the theme in the context of both.
• Set your own research in the framework of previously published works that argue for the necessity for further research.

Operational agricultural meteorology is a critical field that applies meteorological knowledge and tools to support agricultural decision-making, enhance crop yields, and mitigate the impacts of weather and climate variability on agricultural systems. Effective collaboration and coordination among various stakeholders are essential for the successful application of agricultural meteorology (Fig. 12.1).
This chapter explores the linkages between key players in operational agricultural meteorology, including national meteorological services, research organizations, development departments dealing with agriculture and allied sectors, agricultural universities, and non-governmental organizations (NGOs).
Importance of Collaboration in Agricultural Meteorology
The integration of meteorological information into agricultural practices requires a multidisciplinary approach. By working together, stakeholders can ensure that weather and climate data are accurately interpreted and applied to support farmers, policymakers, and other decision-makers. Collaboration can lead to improved agricultural productivity, reduced risks associated with weather extremes, and more sustainable agricultural practices.
12.1. Key Stakeholders and Their Roles
• National Meteorological Services (NMS): Provide weather and climate data, forecasts, and warnings that are critical for agricultural planning and management.    

Abstract

The forest cover has declined at an estimated rate of 3-3.5% per annum due to huge deforestation in many countries during last decades. Being the prime necessity for forest regeneration, importance of quality seed management and its handling procedures have been genuinely recognized for greater interest of the environmental stability throughout the world. Growing of new trees and forests would play a major role to save the future world particularly under the present scenario of climatic change and this implies an increased demand of quality forest reproductive materials.
