Length-weight and length-length relationships for some continental fishes of northwestern Baja California, Mexico

Abstract

Length-weight and length-length relationships were estimated for 10 freshwater, estuarine and marine fish species caught at the mouths of coastal sterams from northwestern Baja California (Mexico). The parameter b estimated by nonlinear least squares of weight and length data, ranged from 2.50 to 3.61. Size conversions (calculated total length from standard length) can be used in fishery for understanding several aspects of population dynamics.

Length-weight and length-length relationships for nine rocky tidal pool fishes along the Pacific coast of the Baja California Peninsula, Mexico

“…Since the samples of each species included individuals that were collected over several seasons, parameters a and b were treated as mean annual values (e.g. González‐Acosta et al., 2004; Ruiz‐Campos et al., 2006).…”

Length-weight and length-length relationships of eight fish species from river Ganga, India

“…Because, in field condition, weight measurements are less accurate and time consuming as compared to length measurements (Karna, ). LWR is also partly an important parameter for fish stock and population assessments (Chu, Hou, Tsong‐Ueng, & Wang, ; Ruiz‐Campos, Gonzalez‐Acosta, & Cruz‐Aguero, ). Recently, numerous attempts are made to study LWRs as well as LLRs of indigenous freshwater fish species from Indian waters (Baitha et al, ; Borah et al, ; Koushlesh et al, ; Nath et al, ; Sandhya et al, ).…”

Length-weight relationship of three Cynoglossus species (C. puncticeps , C. lingua and C. lida ) from Chilika lagoon, India

“…In fisheries, knowledge on length–weight relationship (LWR) is important parameters in fish stock and population assessments (Chu, Hou, Tsong‐Ueng, & Wang, ; Ruiz‐Campos, Gonzalez‐Acosta, & De La Cruz‐Aguero, ). The main application of LWR is to convert length data from the field studies into weight data because in field data collection, weight measurement is quite difficult and time consuming.…”
