Length–Weight Relations of 34 Fish Species Caught by Small-Scale Fishery in Korinthiakos Gulf (Central Greece)

Abstract

Body size is the most easily measured universal characteristic and its relation with body weight has been extensively documented in fisheries research (Froese et al. 2011). The Length-weight (L-W) relation of a species depends on many factors (i.e. sex, size range, habitat, food availability, and fishing pressure), but may also vary seasonally (Froese 2006, Karachle and Stergiou 2008, Liousia et al. 2012. However, studies focusing on seasonal L-W relations are rather limited compared with those on annual estimates, because most of the estimates are based on samplings conducted during short-term periods in an annual basis.In Greek fisheries, L-W relations are mostly derived from sampling conducted in open sea (using trawls and purse seines; for reviews see: Stergiou and Moutopoulos 2001, Karachle and Stergiou 2008) than in coastal waters (smallscale fishery; Moutopoulos and Stergiou 2002), despite of the multi-gear nature of the fishery. Small-scale fishery is of great importance to the Greek fishery contributing 57.3% to the total Greek fisheries landings (Moutopoulos and Stergiou 2012). It involves approximately 30 000 fishers characterized by low income, elementary education and living in small and isolated islands (Tzanatos et al. 2005). Likewise, in the study area (Korinthiakos Gulf) the small-scale fishery component is highly contributing to providing approximately 74% of the total landings (Moutopoulos and Stergiou 2012).In the presently reported study, we calculated annual and seasonal estimates of L-W relations for the most abundant fish species caught by a professional small-scale ves-

Morphological parameters of abundant and threatened chondrichthyans of the northwestern Mediterranean Sea

“…Parameters a and b of C. monstrosa , blackmouth catshark Galeus melastomus and common torpedo Torpedo torpedo have similar values to those found in the Atlantic coastal waters (Ferreira et al., ; Veiga et al., ; Torres et al., ). Lesser spotted dogfish Scyliorhinus canicula values are also similar to those obtained in Atlantic waters and the eastern Mediterranean (Güven et al., ; Moutopoulos et al., ), but differ from those described by Morey et al. () in the Balearic Islands, probably due to the low sample size.…”

Length-weight and length-length relationships of Red Scorpionfish (Scorpaena scrofa L. 1758) from Aegean Sea (Turkey)

“…In fisheries biology, LWRs and LLRs results can be useful in comparing the stocks of the same species in different habitats. These are useful tools when evaluating fish species living in both freshwater and marine habitats (Moutopoulos et al, 2013;Cengiz, 2013). There are several studies were conducted about length-length and length-weight relationships marine and freshwater species (Karachle et al, 2015;Tsagarakis et al, 2015;Yılmaz et al, 2015;Bostancı et al, 2017;Saygın et al, 2018;Yedier et al, 2019aYedier et al, , 2019b.…”

Length–weight relations of 24 fish species (Actinopterygii) from Hirakud Reservoir, Odisha State of India

“…It provides information on the condition factor and somatic growth type (isometric or allometric) of fish species (Le Cren 1951, Froese 2006, Froese et al 2011) and therefore it is used for the determination of the biomass, enabling the conversion of length to weight. This relation has also been used in life history studies (Petrakis and Stergiou 1995, Froese 2006, Froese et al 2011, for comparison of species growth between sexes, different seasons, and regions (Froese 2006, Moutopoulos et al 2013 as well as an index of habitat trophic state (Tsoumani et al 2006, Moutopoulos et al 2011.…”
