Length-weight relationships of Acanthopagrus longispinnis (Valenciennes, 1830), Raconda russeliana (Gray, 1831) and Coilia neglecta (Whitehead, 1967) from the Bay of Bengal coast, Bangladesh

Abstract

Current study reports the length‐weight relationships (LWRs) of three marine fish species collected from the fishermen catches covering three seasons i.e., rainy, autumn and winter between June, 2016 and February, 2017. Fishermen caught the species using beach seine net (3.5 cm mesh size) and set bag net (0.5 cm mesh size) up to 200 m far away from the shoreline. The LWRs for fish species were W = 0.0180TL3.192 for A. longispinnis, W = 0.0109TL2.971 for R. russeliana and W = 0.0098TL2.942 for C. neglecta with their r2 values of 0.971, 0.962 and 0.997, respectively.

Length‐weight relationships of seven cyprinid fish species from the Kaptai Lake, Bangladesh

“…Length‐weight relationships (LWRs) are important biological parameters used in fish population dynamics to estimate biomass by converting length observations into weight (Chaklader, Siddik, Hanif, Nahar, & Islam, ; Hanif, Islam, Siddik, & Chaklader, ; Martínez‐González, González‐Daza, & Mojica, ; Siddik, Chaklader, Hanif, Islam, & Foteder, ). It also provides baseline information for estimating growth pattern of fish as a part of stock assessment, management and conservation strategies (Ortega‐Garcia, Sepulveda, Aalbers, Jakes‐Cota, & Rodriguez‐Sanchez, ).…”

Length–weight relationship and size at maturity of the Picnic seabream, Acanthopagrus berda (Forsskål, 1775)

“…Isometric growth is exhibited in fishes when their length increases in equal proportions with body weight from constant specific gravity 31,32 . Earlier studies stated that the differences in ‗b' value can be attributed to several factors like the physical condition of water, diet, stomach fullness, sex, gonad maturity, growth phase, season, specimen number and habitat [33][34][35][36][37] .…”

Length–weight relationships of three carangid fish species Alepes vari (Cuvier, 1833), Uraspis uraspis (Günther, 1860) and Carangiodes oblongus (Cuvier, 1833) from the Bay of Bengal coast, Bangladesh

“…The observed value of parameter “ b ” for A. vari and C. oblongus represents is higher than the Bayesian LWRs value while the value is somewhat lower for U. uraspis . These dissimilarities could be linked with food and feeding rate, habitat, growth phase, gonad development, sex, season, length range of sampled specimens and nutritional status of fish (Chaklader, Siddik, Hanif, Nahar, & Islam, ; Hanif, Siddik, Nahar, Chaklader, & Fotedar, ; Lim, Chong, Lim, & Yurimoto, ; Siddik, Hanif, et al, ). None of these factors were explored in the present study.…”
