Length-weight relationships of 10 freshwater fishes from the Busan Metropolitan City in South Korea

Abstract

Summary The length‐weight relationships (LWRs) for 10 freshwater fish species in catchment area of Busan Metropolitan City, South Korea, were analyzed. Fish samples were collected quarterly using scoop‐nets (mesh 5 mm), casting nets (mesh 7 mm) and gill nets (mesh 20, 50 and 70 mm) from 2011 to 2016. LWRs data for seven of these species have not yet been listed in FishBase.

Length-weight relationships of three freshwater fishes from Hoiya River in South Korea

“…Parameter b indicates isometric growth in body proportions, more than 3 of b parameter is a good criterion of fish condition (Froese, ). Mean of our LWRs regression coefficients (3.23) were higher than other developed areas (3.02 and 2.96) (Kim et al, ; Sani et al, ). Considering these LWRs factor, catchment for Hoiya River is a more natural‐like environment compared with other river catchments in developed areas.…”

Length-weight relationships of 4 fish species from a seagrass Zostera marina bed in Koje Bay, Korea

“…The LWR of each species was estimated based on the equation: log W &#003D; log a + b log L, where log a is the regression intercept and b is the regression slope. Prior to regression analysis, the log‐log plots of length and weight data were performed to remove obvious outliers (Froese, ; Kim et al, ). Scientific names for all species and family assignments were according to FishBase.…”
