          Abstract

          The present study was aimed at understanding the impact of COVID-19 pandemic related restrictions on the freshwater aquaculture sector of Andaman and Nicobar archipelago (ANI). We interviewed the freshwater fish farmers ( N = 211) covering all the three districts (North and Middle, South Andaman, Nicobar district) of the archipelago. The results revealed the critical issues faced by the stakeholders such as fish seed unavailability, limitations in feeding, insufficient logistical support, movement related restrictions, lack of inputs, manpower shortages, etc. as the important constraints during lockdown. Our surveys also revealed that there was a significant reduction in the income of the farmers post COVID-19 outbreak ( p < 0.001). Possible reform strategies that could promote the sector development and resilience were outlined to recover from the COVID-19 impacts. The study also highlights the significance of effective networking among the stakeholders and necessary preparedness measures to be undertaken by the fish farmers to deal with the exigencies. The study also recommends a policy framework to strengthen the planning and management of freshwater aquaculture sector towards the path of sustainability.

            Beta-glucan: an ideal immunostimulant in aquaculture (a review).

            The major hindrance in the development and sustainability of aquaculture industry is the occurrence of various diseases in the farming systems. Today, preventive and management measures are central concern to overcome such outbreak of diseases. Immunostimulants are considered as an effective tool for enhancing immune status of cultured organisms. Among different immunostimulants used in aquaculture practices, β-glucan is one of the promising immunostimulant, which is a homopolysaccharide of glucose molecule linked by the glycoside bond. It forms the major constituents of cell wall of some plants, fungi, bacteria, mushroom, yeast, and seaweeds. Major attention on β-glucan was captivated with the gain in knowledge on its receptors and the mechanism of action. The receptor present inside the animal body recognizes and binds to β-glucan, which in turn renders the animal with high resistance and enhanced immune response. This review highlights β-glucan as an immunostimulant, its effective dosages, and route of administration and furthermore provides an outline on role of β-glucan in enhancing growth, survival, and protection against infectious pathogens pertaining to fishes and shellfishes. Study also summarizes the effect of β-glucan on its receptors, recognition of proteins, immune-related enzymes, immune-related gene expression and their mechanisms of action.
