More about cod

Spawning and recruitment success of cod in the eastern Baltic Sea depend at great extent of environmental conditions. Spawning is confined to deep areas where salinities are sufficiently high to allow egg fertilisation and to keep fertilised eggs float and sufficient oxygen content in deep saline water layer is crucial to egg survival.

Adult stages of cod feed mostly on sprat and herring and juvenile cod suffer also from cannibalism. The extent of cannibalism might differ depending on predator abundance and juvenile concentration, which depend upon the habitat volume occupied and the overall abundance of cod.

More about the fishing methods

The demersal or bottom otter trawl is a towed fishing gear designed and rigged to have bottom contact during fishing, towed by large trawl vessels, typically in excess of 15m. Instruments to monitor gear performance are common in modern bottom otter trawling. Such instruments monitor geometry (door distance, vertical opening, bottom contact, trawl symmetry), trawl depth water temperature and the weight of catch in the trawl is also closely monitored (catch sensors) to give an indication of the appropriate moment to haul.

Longlines are market by Dan buoys with vessel identification and radar reflector. Longline fishing is a method consisting of a long line, onto which leaders are fixed at regular intervals (usually every 2‐2.5 meters). Attached to these are hooks with some sort of bait on them. Cod longline fishing uses herring as bait. Approximately three thousand hooks are used per vessel.

Commercial market

Cod from the Baltic sea is mainly processed by processors in Poland and sold to a variety of European markets as fresh and frozen fillets, loins etc, as well as battered/breaded products.
