Impact of feed on the yield of Litopenaeus vannamei and Macrobrachium rosenbergii prawn culture from West Godavari district, Andhra Pradesh, India

Abstract

Aquaculture, a vital sector addressing global food demand, is characterized by its extensive water requirements. Categorized into mariculture, freshwater aquaculture, and brackish water aquaculture, the sector plays a crucial role in food production. This study focuses on prawn cultivation, a significant aspect of aquaculture, emphasizing the influence of feed quality and hydrographic parameters on yield and ecological sustainability. Conducted in Vissakoderu village (Litopenaeus vannamei) and Eduru village (Macrobrachium rosenbergii), the research employed commercial feed, optimizing physicochemical parameters such as temperature, pH, and salinity. Probiotics were integrated into the feed to enhance prawn growth. Results indicated optimal levels of moisture, lipids, protein, fiber, carbohydrates, minerals, and vitamins in the feed. The progressive weight gain of prawns, reaching 30.00 kg for 1000 prawns, was correlated with an increased feeding frequency. Scientifically monitored hydrographic conditions and feed quality contributed to a remarkable average yield of 29 tons for Litopenaeus vannamei and 63.33 tons for Macrobrachium rosenbergii over three years. This underscores the importance of precision in aquaculture practices for both yield enhancement and ecological preservation. The study provides valuable insights into the sensitivity of prawn cultivation, emphasizing the need for meticulous care in managing hydrographical, feed, and disease parameters.
