Chitosan nanoparticles have received a lot of attention in recent years due to their beneficial properties as healthy supplement to supply bioactive substances in the food industry and nutrition. The purpose of this study was to investigate the influence of chitosan nanoparticles (CsNPs) as nutritional stimulus at the early feeding for the Nile tilapia ( Oreochromis niloticus ) fry on the growth performance, feed efficiency, and histomorphological health of the liver and intestine. Graded levels of CsNPs (0.05, 0.1, 0.2, 0.4, 0.8, and 1.6g kg −1 diet) were added to

The study examined the impacts of varying protein levels and additional substrate area for periphyton formation on the growth and survival of whiteleg shrimp postlarvae reared in a biofloc system. Shrimp postlarvae were stocked in eighteen 100L tanks each filled with 60L of seawater (28 ‰ salinity). In a 3×2 factorial arrangement, the experimental diets were formulated to contain three varying dietary protein levels (25, 35, and 45% CP). Shrimp diets were prepared and supplied

provide an affordable and readily available source of animal protein for human consumption that plays a vital role in maintaining the livelihoods of Bangladeshi people. The study was conducted to evaluate the proximate composition of five different small indigenous fish species (SIS): viz ., Glossogobius giuris , Mastacembelus pancalus , Mystus tengra , Heteropneustes fossilis , and Puntius ticto . The samples were collected from the Mathabhanga River. The proximate composition of the studied samples revealed varying proportions of moisture content (68.60 to 79.05%), crude protein (46.22 to 65.99%), crude fat (4.77 to 22.93%), ash content (12.03 to 19.22%), carbohydrate (11.22 to 15.73%), crude fiber (0.09 to 0.25%), whereas the energy value was 374.04 to 444.91Kcal/ 100g. Among the examined fish species, Glossogobius giuris contained significantly (P< 0.5) higher level of protein content but less amount of lipid content. Addittionally, Puntius ticto showed significantly (P< 0.05) higher lipid, ash and energy contents as compared to others. The results of the study clearly revealed that Glossogobius giuris and Puntius ticto fish species are rich in macronutrients in alliance with the tested fish species. Hence, the research findings suggest that commonly consumed small indigenous fish species (SIS) offer a valuable source of high-quality protein and essential macronutrients. This implies that the consumption of these fish can help alleviate protein and other nutrient deficiency, as well as livelihood security in Bangladesh. Further biochemical and molecular research can be conducted to analyze all the essential nutrients and genetic improvement of the fish.
