Incidences of white feces syndrome was reported in reared farms of Penaeus vannamei during January 2022 in many shrimp farms of Razole, East Godavari, and Andhra Pradesh, India. This was commonly observed in 30-50 DOC (days of culture). A total nine types of water quality parameters were taken to observe how this parameter enhances the White feces syndrome. The early indication of white feces syndrome is identified by white fecal strings is floating on the surface of the water. In severely affected shrimp hepatopancreas and gut becomes white and pale yellow in color. In this study recommendations were made on how to control White feces syndrome by using Probiotics and natural remedies.

Fisheries sector has an important role in Indian economy, as it provide more than 2.8 cores job directly or indirectly to the primary level fishers and fish farmers. Globally the aquaculture production raised by triple in weight which was 34 MT to 112 MT from 1997 to 2017. In India this sector contributing 7.8% of agriculture’s GDP. In Chhattisgarh about 2.20 lakh of persons are employed in fisheries sector and most of them are belongs to the under privileged section of society. Fish production in Chhattisgarh has increased by the average of 315% from the base year 2007-08 to current year 2020-21. The study was conducted in the Mungeli district of Chhattisgarh. Mungeli and Pathariya blocks were selected for the study. Based on the performance, 4 SHG’s and 4 Fishermen cooperative groups were identified and total of 40 and 112 respondents were interviewed by pre-tested questionnaire respectively. It was found that the total cost incurred by SHG’s and Fishermen cooperative groups per hectare was Rs. 47658.73 and Rs. 60354.00 respectively. The average production of fish was found to be 18.15 and 27.90 quintals with a net return of Rs. 151991.27 and Rs. 260496.00 per hectare, having a B:C ratio of 1:3.18 and 1:4.31 in SHG’s and Fishermen cooperative groups respectively.

Plant sources of protein are the most appropriate alternative for Fish Meal (FM) for preparation of fish diet. Therefore, plant protein is the lower price, greater availability and improved consistency of composition. Compared to fish meal, they vary in their nutrition and biological values and lower palatability. In order to improve nutritional quality of plant protein sources by using processing technologies such as Solid state fermentation has been considered for the production of enzymes, antibiotics, extrusion cooking, other value-added products to produce high quality aquatic feeds. Besides that, biotechnology to get better safety, freshness, color, flavor, texture, taste, nutritional characteristics and shelf-life of cultured food products. In addition, mixed feeding from plant protein source in which high protein diet is alternated by a low protein diet could result in improved nutrient utilization. Thus, to take practical and possible measure in order to enhance nutritional quality of plant protein sources by using extrusion cooking processing, genetically modified, biotechnology, feed additives, nano-particles and solid state fermentation technologies. Hence, the issue of cheaper sources of plant protein feed ingredients would be requisite to fully replace fish meal for the improvement and sustainable of fishery industry in developing countries.
