Background. It is a common perception that growth rates of many commercially-exploited fish species have been well known. It is evident, however, that in certain cases, especially in brackish water environments those growth rates may be diversified. Therefore, determination of growth patterns of various stocks of the same fish, living in different salinity regimes may be important for efficient fisheries...
Background. Vendace, Coregonus albula (L.), is one of the most valuable components of Polish lake ichthyofauna. The vendace from different lakes differ in their principal vital characteristics (such as growth rate etc.) and it is therefore crucial to determine those characteristics from different throphic types of lakes in order to implement proper measures of fisheries management for those coregonids...
Background. Bassan barbel, Barbus pectoralis Heckel, 1843, is widely distributed in the lakes and river systems of Turkey and its neighbouring countries. Bassan barbel is a fish species of commercial value. The aim of his study was to provide necessary biological features of bassan population from Kemer Reservoir. Materials and Methods. Biological aspects of Bassan barbel were studied based on a total...
Background. Gobius paganellus L. is one of the most common gobiid fish in the south-eastern Black Sea. The aim of present study is to provide information on age structure and growth, length at sexual maturity, annual cycle of gonad development, and diet of rock goby in the south-eastern Black Sea. Materials and Methods. One hundred seventy-five specimens of G. paganellus were sampled from two stations...
Background. Loach fishes, Cobitis sp., are found in the majority of streams in the southern Caspian Sea basin, but reproductive parameters of them are barely known. Reproductive conditions are key parameters of fish populations and their assessment is very important for several reasons. Therefore, the main aim of this study was to obtain reproductive characteristics of this fish which will be a first...
