A review of various biological parameters for fish from the Greek Seas KONSTANTINOS I. STERGIOU* and PARASKEVI K. KARACHLE Laboratory of Ichthyology, Department of Zoology, School of Biology, Aristotle University of Thessaloniki, Thessaloniki 54124, Greece Abstract In this paper, various biological parameters for 142 fish stocks (i.e., maximum observed length and age, Lmax and tmax, for 117 and 57 stocks, respectively; von Bertalanffy growth parameters, K and LΞ, for 72 stocks, and to, for 58 fish stocks) from the Greek Seas were collected. These stocks belong to 46 fish species. Significant relationships between the parameters K and LΞ, K and tmax, and Lmax and LΞ for all Greek stocks for which such data are available, using the original reported length, and after transformation of various types of length to total length, were also identified. These relationships can be used to estimate K and LΞ from tmax and Lmax respectively, for either rare fish species or for species for which such information is not available, provided that their tmax and Lmax are within the range of these used for the development of the regressions.   < back .
