Twelve ponds from two villages such as Sutiakhali and Salakandi under Mymensingh sadar upazila were selected for the study. The average pond size was 5.5±0.23decimal with a stocking density of 600 shing dec-1. The ponds were only fertilized with rabbit dung except at the time of pond preparationat a rate of 1 kg dec-1. Various environmental parameters such as temperature (oC), transparency (cm), PH, dissolve oxygen (mg L-1), PO4-P (mg L-1), NO3-N (mg L-1), NO2-N (mg L-1), NH3-N (mg L-1), chlorophyll and alkalinity (mg L-1) were monitored once in a week. The parameters were found to vary little from pond to pond and most of the parameters were within the suitable range for freshwater aquaculture in Bangladesh. The highest survival rate of fish was 95.36 ± 0.15 % in treatment T1 and the lowest was 90.39 ± 0.10 % in treatment T2. The survival rates of fish were not significantly different among the treatments (P > 0.05). The production of fish in T1 and T2 treatment was 25.36 and 20.43 kg dec-1, respectively. Daily growth of shing in two treatments were 1.95 ± 0.01 and 1.88 ± 0.01 % respectively. The study revealed that integrated shing-rabbit would be highly profitable using improve extensive culture system in the rural household ponds through effectively reducing the use of pond fertilizer and fish feeding cost.","PeriodicalId":213044,"journal":{"name":"Bangladesh Journal of Fisheries","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139366249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was carried out to analyze the gut contents of pool barb, Puntius sophore. A total of 180 specimens of P. sophore was examined on monthly basis for the period of study. Numerical method, points method, frequency of occurrence method and index of fullness method were employed to analyze data obtained from the gut contents of P. sophore. A total of 42 genera of phytoplankton, 13 genera of zooplankton and 1 insect larva were observed in the diets. Proportions of occurrence of Chlorophyceae, Bacillariophyceae and Cyanophyceae were almost equal and the highest percentage of total point was 54.13 in Cholorophyceae and the lowest 2.76 was in Rotifera. Chlorella was the dominant genus among phytoplankton; on the other hand, Brachionus was the dominant genus among zooplankton. The highest gut content was observed in March with average index of fullness of 3.21 and the lowest was in September with average index of fullness of 1.67. Average gut content of the fishes belonging to size group-2 (47-69 mm) was found higher with average index of fullness of 2.70 than those of other two size groups (24-46 mm and 70-91mm). With the increase of size of fishes, the intake of Bacillariophyceae and Cyanophyceae decreased while that of Chlorophyceae and zooplankton increased. The present investigation reveals that P. sophore is an omnivorous fish but phytoplankton is the most prevalent food item.","PeriodicalId":213044,"journal":{"name":"Bangladesh Journal of Fisheries","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127580209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifteen morphometric and six meristic characteristics were selected. Eight morphometric characteristics were significantly different (p<.05) among the regions; three characteristics were highly significant (p<.001) in Kurigram (Pre-orbital distance, PrOD; Lower-jaw length, LJL; Upper-jaw length, UJL) indicating C. orientalis population of Kurigram was significantly different (p<.001) from the other two locations. On the other hand, among six meristic characteristics, number of dorsal fin rays (DFR), pectoral fin rays (PFR), anal fin rays (AFR), and branchiostegal rays (BR) were found to be significantly different among three locations. The values of PFR varied significantly (p<.05) in Kurigram, which distinguishes the other two regions. Likewise, DFR and BR showed significant variations in the Rangpur region, whereas AFR significantly (p<.001) separated the Lalmonirhat population from the others.
