Feeding ecology of Parapenaeus longirostris (Lucas, 1846) (Decapoda: Penaeidae) from the Ionian Sea (Central and Eastern Mediterranean Sea)*

摘要: The purpose of this paper is to investigate the feeding habits Parapenaeus longirostris 1 in Greek and Italian Ionian Sea. individuals were caught from September 1999 July 2000 on a seasonal basis (except winter) Sea, August A total 324 males 309 females P. analysed. comparative analysis diet activity was made, taking into account sex, season, size classes study area as factors influencing species. Dietary diversity also estimated. displayed high preference large variety bathypelagic, benthic endobenthic preys, mainly polychaetes, crustaceans molluscs. No clear differentiation behaviour between sexes, including composition activity, observed. increased during spring for spring-summer could possibly be attributed metabolic processes. This species undergoes changes its with ontogeny. Larger specimens more efficient predators than smaller ones, because their greater swimming ability. Sea related different environmental conditions.
