8.1. Biofloc aquaculture

Among the innovations in the field of aquaculture, biofloc technology (BFT) has attracted great attention due to its ability to foster the goals of sustainable aquaculture (Khanjani et al., 2022a). If implemented correctly, BFT capitalizes on the existing organisms in water to significantly reduce water use and environmental impact and increase biosafety at farms (Avnimelech, 2012).

Objective: To get acquainted with classmates.

Description: This is the first lab activity and has been designed to make the students feel comfortable in their new surroundings. The aim is also to help them get acquainted with their classmates as they are still new to each other. This short fun activity will help them mingle and set the tone for upcoming activities.

Date:

Objective: To understand the importance of paralanguage in verbal communication.

Description: Paralanguage is the variation in voice and includes vocal characteristics such as pitch, range, resonance, tempo, etc. Though it is an integral part of verbal communication, it is quite distinct from the actual signs and symbols that are used by the communicator.

Date:

Objective: To practice giving appropriate feedback.

Description: Communication is a cyclic process. The message originates from the source and is reaches the receiver. The receiver then decodes the message (i.e; makes sense)and sends a message back to the sender to convey his/her understanding or agreement with the message that has been received. Feedback not only completes the communication cycle, but also takes the process forward.

Date:

Objective:To understand the concept of perception and its role in communication.

Description: Human body receives stimuli through various sensory organs and the brain processes these stimuli and assigns meanings leading to a reaction. This process of organizing, identifying and interpreting of sensory stimuli leading to an understanding of the environment is called perception.

Date:

Objective: To prepare a non-projected audio-visual aid (folder).

Description: Folder is a single thick sheet of paper, which is usually folded once or twice. Folder contains essential information about a place, event, etc. which is printed on a good quality paper. A folder is prepared as and when needed and is distributed free of cost.

Date:

Objective: To understand shot sizes in a video production.

Overview: Shot, in video production refers to one continuous recording by the camera. It comprises of a series of frames (still images) and There are 24 frames in one second. A shot includes eeverything recorded between switching on and switching off the record button on the camera. It can contain movement of both camera and talent.

Despite the meticulous methodology and extensive analysis employed throughout this research project, it is crucial to acknowledge and address the limitations that arose during the study. By recognizing these limitations, we not only ensure a transparent evaluation of the research process but also shed light on potential areas for future investigations to refine and expand upon the findings.

In this section of the chapter, the limitations encountered in this thesis are highlighted as follows:

Things required for cell culture

1. Lab – having negative pressure (HEPA filter)

2. Safety cabinet (Hood/laminar flow)

a) Biosafety level 1 (BSL-1) – Basic level of protection. Agents handled under this cabinet are NOT infectious.

b) BSL-2 – Appropriate for moderate risk agents. Most of the non infectious cell cultures are done under this facility.

Clinical Symptoms

• Anchor worms can be seen with the naked eye

• Frequent rubbing or “flashing”

• Localised redness

• Inflammation on the body of the fish

• Tiny white-green or red worms in wounds

• Breathing difficulties

Clinical Symptoms

• White/brown cotton-like foci on the surface of the skin and/or gills

• Peritonitis

• Extensive haemorrhage • Necrosis

• Adhesions
