  Background and Objective: Proximate composition of most of the fish feed ingredients available in Bangladesh are unknown to fish feed producers and farmers. That prohibit them to utilize these ingredients in the formulation of low cost fish feed for aquaculture. The objective of the present study was to determine the proximate composition of fish feed ingredients from a wide range of area of Bangladesh. Materials and Methods: A total of 163 samples of 19 different available feed ingredients were collected and analyzed for proximate composition viz. moisture, crude protein, total ash, crude fiber, crude fat and nitrogen free extract (NFE) followed by standard methods. Results: Among the plant origin ingredients, the highest value of crude protein was found in soybean oil cake and thus it can easily replace fish meal and meat and bone meal to produce quality fish feed. Among the animal origin feed ingredients, higher crude protein content was found in protein concentrate and lower in dry trash fish. Crude fat content of plant origin feed ingredients ranged between 0.99±1.31 (rapeseed oil cake) to 18.93±1.07% (soybean full fat) and in animal origin feed ingredients the fat content ranged between 4.08±1.86 (meat and bone meal) and 10.33±2.02% (dry trash fish). Most of the samples of mustard oil cake (88.89%), soybean oil cake (55.56%) and wheat bran and rice bran (B-grade) (100%) were found in lower standard. Conclusion: Knowledge of proximate composition of feed ingredients acquainted in the present study will help to produce low cost quality fish feed from locally available feed ingredients.

  Background and Objective: The study on length-weight relationship (LWRs) and condition factors has a great potential for effective management of a fish species. So the present study was aimed to explore the length-weight relationship and condition factors of a vulnerable fish species Cirrhinus reba. Materials and Methods: A total of 600 individuals of C. reba was collected from Padma River have been evaluated for the present study from five distinct stations during 1 year (From January to December, 2015). Length and weight of the individual fish were measured using a digital slide calipers and an electronic balance. Length-weight relationship was analyzed using the equation: W = a×Lb. Fulton (KF) and relative (KR) condition factors were determined using the equation: KF = 100 W/L3 and KR = W/a×Lb, whereas, relative weight (WR) was calculated using the equation: WR = (W/WS)×100. Results: Total length and weight of the individuals were found to vary from 6.60 -23.80 cm and 2.63-136.00 g, respectively. The LWRs for male, female and combine sex were found highly significant (p<0.01) with good linear regression close to 1 (r<1). Male fishes were found to show isometric growth, whereas, female showed positive allometric growth pattern. Relative condition factor (KR) and relative weight (WR) both were found to show significant (p<0.01) correlation with body weight of C. reba. Conclusion: It was concluded that there was a significant relationship between the growth pattern, length and weight of C. reba in different months. The stock of C. reba from Padma River were in declining trend. However, proper management of this fish species is recommended.
