Capture of wild finfish fry in Mediterranean coastal areas and possible impact on aquaculture development and marine genetic resources


, : Capture of wild finfish fry in Mediterranean coastal areas and possible impact on aquaculture development and marine genetic resources. Israeli Journal of Aquaculture Bamidgeh e; 52(2): 77-88

The collection of wild finfish fry of sea bream (Sparus auratus), sea bass (Dicentrachus labrax) and Mugilidae spp. is widely spread in some countries along the Mediterranean coast. Egypt, Greece, Israel, Italy, Tunisia and Turkey do most of the estimated 195.3 million catch. Of these, 130 million (66.6%) are caught in Egypt, 35.75 million (18.3%) in Turkey, 22.3 million (11.4%) in Italy, 4 million (2.1%) in Tunisia, 3 million (1.5%) in Israel and 0.25 million (0.1%) in Greece. Young mullet fry are used for stocking lakes and lagoons in various culture systems: extensive, semi-intensive and intensive monoculture as well as in polyculture with tilapias and carp. Sparidae and Serranidae spp. are mostly used in extensive and semi-intensive systems. At present, the development of Egyptian marine culture is severely inhibited by a shortage of finfish fry. This paper presents an overview of the existing status of these catches in this region with special emphasis on the Egyptian ecosystem, as well as opinions as to the possible impact they may have on Mediterranean aquaculture and fisheries as well as on marine genetic resources. Some practical attempts to secure the availability of seeds from marine hatcheries are also presented.

Stress-activated protein kinase/c-Jun kinase (SAPK/JNK) is thought to be necessary for preimplantation embryonic development (Maekawa et al., 2005). However, media increases SAPK/JNK phosphorylation and these levels negatively correlate with embry...
