The ages of the oldest male and female were estimated to be 5 and 7 years respectively. The observed mean lengths-at-age of the two sexes differed significantly for age groups gt 1 year. Back-calculated lengths-at-age revealed that the greatest growth occurred during the first year of life; significant differences were then exhibited between the growth rates of the two sexes, resulting in a greater maximum age of females. Females gt 140 mm in length were heavier than males of the same size; both sexes grew allometrically. Mortality rates (total and natural instantaneous mortalities) of males were higher than those of females. Differences in growth rates of the two sexes and dominance of females in age groups gt 1 year were attributed to the earlier onset of maturity in the males.}, keywords = {Pisces}, author = {Vassilopoulou, V. and Papaconstantinou, C.} } @article {10573, title = {Feeding ecology of Mediterranean poor cod, Trisopterus minutus capelanus (Lacepede), from the eastern coast of Greece.}, journal = {Fisheries Research (Amsterdam)Fisheries Research (Amsterdam)}, volume = {19}, number = {3-4}, year = {1994}, pages = {269-292}, abstract = {The stomach contents of Mediterranean poor cod (Trisopterus minutus capelanus) collected off the eastern coast of Greece (Euboikos Gulf) were analyzed. Crustaceans constituted the main food. Shrimps, followed by crabs, were the most important crustacean prey, in terms of frequency of occurrence. Mysids, although dominant in numbers, represented only a small percentage of the diet by weight. Euphausids, Macrura Reptantia and anomurans were the other main crustaceans found in the stomachs, whereas amphipods, copepods, isopods and cumaceans were present in negligible quantities. Fish ranked second in importance and most were epibenthic or demersal species. Variations in the food of poor cod related to its length were mostly qualitative and not quantitative in terms of stomach fullness. Smaller poor cod fed mainly on mysids and crangonids, but, as fish size increased, these food organisms were replaced by large shrimps (mainly alpheids), fish and crabs. Finally, there was evidence for seasonal and regional variation of the quantity and quality of the food consumed.}, keywords = {Pisces}, author = {Chrissi-Yianna Politou and Papaconstantinou, C.} } @article {9864, title = {The demersal fishfauna of the North and west Aegean sea.}, journal = {BiosBios}, volume = {2}, year = {1994}, pages = {35-45.}, keywords = {kape pisces}, author = {Papaconstantinou, C. and Vassilopoulou, V. and Petrakis, G. and Caragitsou, E. and Mytilineou, Ch. and Fourtouni, A. and Chrissi-Yianna Politou} } @article {4281, title = {Feeding habits of piper (Trigla lyra) in the Saronikos Gulf (Greece).}, journal = {Journal of Applied IchthyologyJournal of Applied Ichthyology}, volume = {10}, number = {2-3}, year = {1994}, pages = {104-113}, abstract = {The stomach contents of 246 pipers (Trigla lyra), collected in the Saronikos Gulf (Greece) in 1989 (March to December), were examined to assess the diet, as influenced by season and fish size. Piper is carnivorous from the juvenile stage onward, feeding on a narrow range of epibenthic and benthic prey items. Seasonal variation in feeding activity indicated a higher intensity in summer, which could be related to temperature and/or gonadal maturation. During all seasons mysids constituted the most important food resource by weight, number and frequency of occurrence and were mainly represented by Paramysis helleri and Lophogaster typicus. Brachyurans were the second most important food category, while decapods ranked third. Small pipers fed mainly on mysids and shifted to brachyurans and other decapods as their size increased. Dietary overlap was relatively high, indicating that the feeding spectrum of piper changed little across seasons and size groups. Juvenile piper ( lt 110 mm fork length) displayed curtailment of eeding between December and January.}, keywords = {Pisces}, author = {Caragitsou, E. and Papaconstantinou, C.} }
