Life-history traits of ten commercially important small indigenous fish species (SIFS) in the Oxbow lake (Southwestern Bangladesh): key for sound management.

For the first time, we revealed the life-history traits including growth pattern (length-weight relationships, LWRs), condition factors, form factor (a), first sexual maturity (L), age at first sexual maturity (t), life span (t), natural mortality (M), asymptotic length (L), and optimum catchable length (L) of ten commercially important small indigenous fish species (SIFS) in the Oxbow lake (Baor), southwestern regions of Bangladesh. A total of 1651 specimens were sampled during January to December 2020 with traditional fishing gears including seine nets, gill nets, and lift nets. Individual total length (TL) and body weight (BW) were measured by digital slide calipers and digital balance, respectively.

Differentiation of intraspecific phenotypic plasticity of elongate glassy perchlet, : Insights into landmark-based truss morphometric and meristic variations.

Objective: Understanding intraspecific phenotypic plasticity is a prerequisite to fish stock identification and sustainable fisheries management. In this study, we assessed intraspecific phenotypic plasticity in terms of meristic and morphometric characters of wild populations of elongate glassy perchlet, from two different rivers, namely Madhumati River - Narail (MRN) and Tulshiganga River - Jaypurhat (TRJ), and an ox-bow lake, - Jashore (JBJ) in Bangladesh.

Materials And Methods: In this study, six meristics, 15 conventional morphometrics, and 23-truss-based morphometrics were subjected to a one-way analysis of variance (ANOVA), followed by the Tukey-HSD test.

Nutritional characterization of freshwater mud eel () muscle cooked by different thermal processes.

This paper reports the effects of four popular cooking methods viz. grilling, boiling, frying, and microwaving on the proximate and nutritional compositions of freshwater mud eel (FWME) muscle. The moisture content of raw FWME muscle was 74.

Landmark-based morphometric and meristic variations of freshwater garfish, from four natural stocks of South-Western Bangladesh.

Objective: The morphometric and meristic variations of was studied based on the landmark-based truss network system to assess their phenotypic variations among four different freshwater stocks, . Boluhorpur , Jhenaidah (BBJ) ( = 29); Bhairab River, Jashore (BRJ) ( = 34); Arial Khan River, Madaripur (AKRM) ( = 28), and Bohnni baor, Gopalganj (BBG) ( = 25) in Bangladesh.

Materials And Methods: Seven meristic characters were counted by using a needle.

Chromosomal studies and quantitative karyotypic analysis of Rohu, Labeo rohita.

Chromosomal and karyotypic studies are required for genetic improvement of any organisms. This study was performed to identify individual chromosomes on morphological basis and to characterize a standard karyotype using the fish, Rohu (Labeo rohita, Hamilton, 1822). Colchicine (0.
