Evaluating The Suitability of Cirrhinus Mrigala in a Sintex Tank Culture System: A Promising Experimental Study
This pioneering study conducted by the Department of Aquaculture aimed to assess the suitability of Cirrhinus Mrigala, a freshwater species, for cultivation in a Sintex tank. The objective was to determine the growth potential and productivity of Cirrhinus Mrigala in this specific tank culture system. Over a period of 60 days, the final weights of the fish specimens were recorded as follows: 2.0g, 4.30g, 6.96g, 9.98g, 11.21g, and 14.17g, respectively. The total fish yield achieved during this period was 437.58 grams, utilizing a natural feeding regime. This study provides valuable insights as the first investigation in this domain, revealing promising indications for the implementation of Sintex tank culture for Cirrhinus Mrigala cultivation
Exploring the Natural Preservation Potential of Aqueous Guava Leaf Extracts on Pangasius Pangasius: An Experimental Study
Fish, being a significant biological indicator in water, serves as a valuable food source once harvested. However, the high protein content in fish makes it an ideal medium for microorganisms, which can lead to spoilage. In areas without access to freezers or ice, preserving fish becomes a challenge. The objective of this study is to investigate the efficacy of Psidium guajava (guava) leaves as a natural preservation method for Pangasius pangasius fish. Key parameters, including gills, eye, texture, odor, and mucilage, were used to evaluate fish quality. Leaf methanolic extract was applied at doses of 0%, 20%, 40%, 60%, and 80%. Data were collected between 1 and 3 days after storage. Results showed that fish quality declined and began to deteriorate after 2 days of storage, particularly in the control treatment (0% extract). However, the fish samples treated with doses of 60% and 80% experienced relatively good quality over the course of 2 days. Although some spoilage occurred in these samples, they remained suitable for consumption. In contrast, fish samples treated with other doses exhibited complete spoilage and were no longer consumable. In conclusion, guava leaf extracts offer a promising alternative for fish preservation
