Length-weight and length-length relationships of fish species from the Aegean Sea (Greece)

Abstract

We present the relationships between total (TL), fork (FL) and standard (SL) length for 37 fish species and the relationships between TL and wet weight for 40 fish species from the Aegean Sea (Cyclades; Greece). The relationships between TL, FL and SL were all linear (for all cases: r2 > 0.928). The values of the exponent b of the length–weight relationships ranged from 2.235 to 3.704.

Distribution and biological features of the common pandora, Pagellus erythrinus (Linnaeus, 1758), in the southern Tyrrhenian Sea (Central Mediterranean)

“…The length-weight relationship of P. erythrinus (sexes combined) shows a negative allometry, which is in accordance with results of previous studies (Hashem and Gassim 1981;Livadas 1989;Santos et al 1995;Moutopoulos and Stergiou 2002;Hoşsucu and Ç akır 2003;Metín et al 2011;Fiorentino et al 2012). Moreover, males show a higher allometry coefficient than females.…”

Length-Weight Relationship and Relative Condition Factor of Clarius batrachus (Linnaeus, 1758) from Gaurmati Fish Farm, Kawardha, Chhattisgarh, India

“…From length-weight parameters (a, b), fishes are affected by a series of factors such as season, habitat, gonad maturity, sex, diet, stomach fullness, health, preservation techniques and annual differences in environmental conditions (Bagenal and Tesch, 1978;Froese, 2006). Such differences in "b" values can be described to one or a combination of factors including differences in the number of specimens examined, area and season effects and distinctions in the observed length ranges of the specimens caught, to which duration of sample collection can be added as well (Moutopoulos and Stregiou, 2002). The relative condition factors were similar to the values (1.04) documented by (Chaudhary and Srivastava, 2013) for C. batrachus under poor availability in natural conditions from Unnao, Uttar Pradesh.…”

Comparison of the Allometry Coefficient of the Length-Weight and Length-Length Relationship between Selene brownii, S. vomer and S. setapinnis Caught in the Gulf of Mexico

“…Thus, it is very useful to determine the length-length relationships of species in different environmental conditions; they are also important for comparative studies of relative growth (Moutopoulos & Stergiou, 2002). In studies of fisheries, it is often more easy and quick to measure the length of the fish than their body mass.…”
