Fisheries Biology Section
Head of Section: Prof.Dr. M. Alp SALMAN
In the section, the bio-ecological and systematic studies are being carried out on the aquatic vertebrates, mainly bony and cartilaginous fishes, aquatic reptiles and mammals, as well as invertebrates (cephalopods and crustaceans) living in the seas around our country, lagoons (including fish weir). There are also many finished and ongoing research projects on the sustainable management of the economically important fish stocks and the conservation of endangered aquatic species. Practical training is continuing at the undergraduate and graduate level with the academic staff specializing in fish biology (growth, age determination, reproductive biology, nutrition ecology etc.), ichthyoplankton (fish eggs and larvae), aquatic reptiles and mammals. Fishing Biology laboratories work on the identification of the above species, reproductive types and environments, egg productivity (fecundity), digestive system contents, determination of metric and meridian characters, and histological examination of tissues. In this concept, fish and other aquatic organisms are sampled by different fishing methods like a bottom trawl, purse seine, beach seine, trammel or fyke nets and then immediately examined in the laboratory or fixed in formaldehyde or ethanol for later studies. For fishes, after the recording of the length, weight data and sex of the samples, hard tissues like scales, otoliths, and vertebrae of the species are removed for age determination of species and their ages read under a stereo microscope. Later the age data are used to find out growth parameters of the fishes. In order to determine the reproductive characteristics of aquatic organisms (fish, cephalopods, crabs), the maturity of the ovary and testes sampled from female and male individuals are investigated histologically. In addition, egg counts are performed by examining ovaries under a microscope in order to determine egg productivity of females. In addition to the biological studies mentioned above, there are also studies on the egg and larvae of fishes. For this purpose, plankton samples obtained vertically or horizontally with plankton nets are separated from zooplankton material in the laboratory, and species are determined and photographed under a stereo microscope. These investigations reveal the environmental preferences and reproductive patterns of the species. After evaluating the data obtained from our studies, the stock status of fish and other economic aquatic organisms are determined in our seas and lagoon environments, contributing to the sustainable fisheries of our country's living marine resources.
