The veined rapa whelk (Rapana venosa) is an invasive species of gastropod native to the western Pacific and now widespread in the Black Sea. The animal is carnivorous feeding on other molluscs and is known to be very resilient tolerating a range of temperatures, salinities, oxygen levels and pollution.
The Romanian fisheries and aquaculture sector has seen some interesting and possibly profound developments in the last couple of years. Possibly the most momentous is the new fishing auction in Tulcea, the first of its kind in the country, that is due to start operating later this year.
Romania’s capture fisheries are mainly from freshwater. In the Black Sea catches are nominal with the exception, in the last few years, of veined rapa whelk, captures of which have caused marine capture production to almost equal that from freshwater. However, it is the aquaculture sector that is responsible for the bulk of domestic production. Strategies that will lead to a sustainable increase in output from these two sectors are the province of the Ministry of Agriculture and Rural Development, where Ioan Utiu, the State Secretary, has a key role to play.
Ukraine has 1.5m ha of water surface that can be used for fish farming. This includes freshwater reservoirs, lakes, and ponds as well as estuaries called limans in the Black Sea and the Sea of Azov. The aquaculture sector in the country farms fish in different ways, in ponds, cages, and in recirculation systems.
The loss of Crimea had a substantial impact on the fisheries sector in the Ukraine. According to the State Agency for Fisheries catches plummeted by 60% from 225 thousand tonnes in 2013 (including Crimea) to 91 thousand tonnes in 2014 (without Crimea). But Ukraine has significant natural resources even without Crimea. These include inland waters (rivers, lakes, ponds, reservoirs) amounting to 1.3m ha, as well as marine waters in the Black Sea and the Sea of Azov. Altogether, Ukrainian waters, both fresh and marine, have an area of 10.4m ha.
Inland waters in Serbia comprise rivers, of which the Danube (the longest), Sava, and Tisza are navigable, two natural lakes and several artificial lakes. These resources support a commercial freshwater fishery, a recreational fishery, as well as an aquaculture industry. The freshwater fishery in Serbia is organized on 65,980 km of rivers and streams and about 150 artificial lakes and reservoirs. The northern parts of Serbia have 30,000 km of canals, which are also suitable for fishing.
The Italian aquaculture sector has a long history starting first in the coastal lagoons and then, as technology became available, expanding both inland and along the coast. While the freshwater production of trout is in terms of volume by far the most important, other freshwater species such as sturgeon and eels are also produced in significant volumes.
The fish market at Chioggia is one of the biggest in the region. Transport bottlenecks constrain its expansion and the authorities would like to move it to an area that is better connected to the road network.
The Italian production of fasolari (Callista chione) takes place in the Northern Adriatic waters, falling in the two Italian regions of Friuli Venezia Giulia and Veneto and is managed at compartmental level (sub-regional level) by the Consortia (CO.GE.VO.) of Chioggia, Venice and Monfalcone. Here the system is based on a co-management approach. The system is based on the integration between the management system (Consortia) and the marketing system (POs). The three above mentioned Consortia work in a coordinated manner by adhering to the same PO, named OP I Fasolari.
