In the past geological eras in the biosphere, species extinction was accompanied by speciation. Ecosystems adapted to a greater or lesser extent to coexist with a species whose activity had become a planetary factor and had a global impact on biospheric processes. One of it is the massive pollution ...

The use of sorbents at present is a promising method for improving fish growing conditions. One of the types of sorbents is vermiculite, a natural mineral that has highly effective sorbing properties. It has been established that it is active against heavy metal ions, organic compounds such as...

Fisheries and aquaculture in developing countries are primarily a way of producing and providing daily food for millions of the world's poorest people and thus contribute significantly to the fabric of local economies. In other countries, fisheries are also valued for sport fishing activities....

Our country has all potential for development of an aquaculture as one of sectors of agriculture, due to a huge number of fresh water areas and the extended line of the seas. Bacterial kidney disease, a chronic disease in the Salmonidae family, causes significant damage to aquaculture development....

Common carp (Cyprinus carpio) has an outstanding economic importance in freshwater aquaculture due to its high adaptive capacity to both food and environment. In fact, it is the third most farmed fish species worldwide according to the Food and Agriculture Organization. More than four million tons...

In evaluating the potentials of oyster (Crassostrea gigans) farming in Novgorodskaya Bay (Posyet Bay), it was concluded that the food requirements of cultured Pacific oyster were 0.46 mg C/specimen for spat and 67.85 mg for commercial-size animals. The probable amount of food was determined as the...

Spring viraemia of carp (SVC) is a rhabdovirus infection, which has a significant economic impact in pond cultures of carp in Europe and western Independent States of the former Soviet Union. The causative agent of SVC, spring viraemia of carp virus (SVCV), has been divided into four subgroups, Ia, ...

Through 50 years of observations, the author followed the formation of the Dactylogyrus fauna of common carp in Hungary. Up until the middle of the 19th century, when intensive fish transfers began, the European common carp subspecies (Cyprinus carpio carpio) has been infected only by three ...

Iron, zinc, manganese, copper and cadmium were estimated in soft tissues of molluscs on wooden and steel supporting pillars of piers, littoral blocks, hydrogeographical buoys, mooring buoys and rope collectors of aquaculture installations. Molluscs inhabiting metal substrates had higher...

Studies were initiated at the Angelinka Experimental Fish Farm (Krasnodar Region, North Caucasus) in 1965. Mass selection was carried out for resistance to dropsy and high growth rate on 3 common carp stocks: local mirror carp (L), a full-scaled Ropsha carp (R), and a line of Ukrainian-Ropsha...
