متن کاملPatchiness and spatial structure of the early developmental stages of clupeiforms in the NW Mediterranean sea
We analyse the spatial structure of early developmental stages of three ecologically important small pelagic schooling species in the northwestern Mediterranean sea: the anchovy Engraulis encrasicolus, the round sardinella Sardinella aurita, and the sardine Sardina pilchardus. We used data on egg and larval abundance (arranged by development stage), hydrographic data and potential prey biomass ...
متن کاملMorphologic and Allozyme Analyses of European anchovy (Engraulis encrasicolus (L. 1758)) in the Black, Marmara and Aegean Seas
The morphologic and genetic variations of Engraulis encrasicolus (L. 1758) were studied based on morphometric, meristic and allozyme analyses. Samples were collected throughout the Black, Marmara and Aegean Seas. Discriminant function analysis of both morphometric and meristic characters indicated the existence of four morphologically differentiated groups of E. encrasicolus. The Aegean Sea and...
متن کاملResearch Article: Life history traits of ribbonfish Trichiurus lepturus (Linnaeus, 1758) in the Persian Gulf and Oman Sea
Ribbonfish, Trichiurus lepturus (Linnaeus, 1758), is an important component of subsistence fisheries throughout its tropical and subtropical distribution. The catch rate of ribbonfish has increased seven-fold in a decade in the Persian Gulf and Oman Sea. We collected monthly biological samples from T. lepturus, to estimate growth and mortality parameters, and identify species reproductive patte...
