Weight-length relationships for 33 fish species in Greek waters

01 Jan 1995-Fisheries Research (Elsevier)-Vol. 21, pp 465-469

TL;DR: Weight-length regressions are presented for 33 fish species caught during 1992–1993 in the South Euboikos Gulf, Aegean Sea and the values of the exponent b in the weight-length relationship W = aLb ranged from 2.320 to 3.521 and the median value was 2.987.

TL;DR: The relationships between TL, FL and SL were all linear (for all cases: r 2 > 0.928) and the values of the exponent b of the length–weight relationships ranged from 2.235 to 3.704.

Abstract: Summary 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: r 2 > 0.928). The values of the exponent b of the length–weight relationships ranged from 2.235 to 3.704.

...Length–weight relationships are important because they: (a) allow the conversion of growth-in-length equations to growthin-weight, for use in stockassessment models; (b) allow the estimation of biomass from length observations; (c) allow an estimate of the condition of fish; and (d) are useful for between-region comparisons of life histories of a certain species (Wootton 1990; Pauly 1993; Petrakis and Stergiou 1995; Gonc¸ alves et al. ......

TL;DR: In this paper, the authors focus on the role of agriculture and fishing in the European level in the Common Agricultural Policy (CAP) and Common Fisheries Policy (CFP) and show that agriculture dominates in terms of direct contribution to GDP and numbers of people engaged in it, as well as accounting for the largest amount of public support expenditure.

Abstract: Agriculture and fishing are the primary source of almost all our food, as well as of many other products, so remain vital activities even though their share in the economy is small and in continuous decline. Partly for this reason public policy in these areas is almost entirely integrated at European level in the Common Agricultural Policy (CAP) and Common Fisheries Policy (CFP). Forestry policies are also heavily affected by EU-level decision-making. As agriculture dominates in terms of direct contribution to GDP and numbers of people engaged in it, as well as accounting for the largest amount of public support expenditure, it is agriculture that will receive the greatest attention here.

TL;DR: Weight-length relationships were estimated for 31 fish species from the south and south-west coasts of Portugal as discussed by the authors, mainly sea breams (Sparidae), which dominate the catches of the main fixed gears used in this region and account for more than 50% and 40% of the total fish landings by weight and by value.

...These WLR are lacking for many species included herein, and therefore we complement those provided by other authors regarding the Mediterranean Sea (Quesada, 1991; Campillo, 1993; Petrakis and Stergiou, 1995; Dulčić and Kraljević, 1996; Merella et al., 1997), on the grounds that for a correct application of the WLR it is advisable to make use of local values....
