Feeding habits of piper ( Trigla lyra ) in the Saronikos Gulf (Greece)

Feeding habits of piper ( Trigla lyra ) in the Saronikos Gulf (Greece) Summary 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 temerature and/or gonadal maturation. During all seasons mysids constituted the most important foof resource by weight, number and frequency of occurrence and were mainly represented by Paramysis helleri and Lopogaster typicus. Brachyurans were the second most important food category, while decapods ranied 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 sectrum of piper chaned little across seasons and size roups. Juvenile piper (< 110 mm fork length) isplayed curtailment of feeding between December ancf January. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

Summary 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 temerature and/or gonadal maturation. During all seasons mysids constituted the most important foof resource by weight, number and frequency of occurrence and were mainly represented by Paramysis helleri and Lopogaster typicus. Brachyurans were the second most important food category, while decapods ranied 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 sectrum of piper chaned little across seasons and size roups. Juvenile piper (< 110 mm fork length) isplayed curtailment of feeding between December ancf January.
