Length-weight relationship, length-length relationship and condition factor of Labeo bata (Hamilton, 1822) from central Brahmaputra valley of Assam

Abstract

The present study was carried out to established the relationship of total length and total weight, the relationship of total length (TL), standard length (SL), and fork length (FL) and also condition factor of native fish species Labeo bata from Kolong River of central Brahmaputra valley of Assam. A total of 334 specimens were collected for this present study from May 2018 to April 2019. The length-weight relationship (LWR) was calculated separately with male, female, and pooled data and growth was shown negative allometric (b<3). The length-length relationship (LLR) showed a linear significant relationship between total length and standard length, total length and fork length and standard length and fork length. Information on the length-weight relationship, length-length relationship and condition factor of Labeo bata from central Brahmaputra valley are quite limited. There is no such information of LWRs, LLRs, and condition factor of this fish species from this area so this result which would be helpful for scientific and sustainable management of Indian minor carp fisheries in the Kolong River of central Brahmaputra valley of Assam.

Length-weight relationships of farmed major carps (Cattla cattla, Labeo rohita and Cirhinus mrigala) fed with different sources of protein in an intensive polyculture

“…All raceways treated with fish meal based diets contained exceptionally high values of slope 'b' (2.5 to 3.5, in case of 25% FM and 35% FM and 3.48 to 3.92, in case of 45% FM). All values were in accordance with the findings of Sarkar et al (2013), Bhakta et al (2019), Deuri et al (2020) and Coulter et al (2018).The obtained values of regression coefficient (r and r 2 ) were also confirmed the aptness of environmental conditions.…”

Shu bilan birga, Orol dengizi havzasidagi daryolarda tarqalgan 14 turdagi endem va mahalliy baliq turlarining LWR koʻrsatkichlari oʻrganilganligi ma'lum(Sheraliev et al, 2022).…”
