Rationale for Restocking the Eastern Baltic Cod Stock

摘要: The Danish Institute for Fisheries Research and Bornholm's Salmon Hatchery examined the potential restocking Baltic cod (Gadus morhua callarias L.) in eastern Sea. This population has adapted to unique brackish water conditions where successful spawning depends on regular inflows of oxygenated saltwater from North Hydrographical are therefore considered constitute principal bottleneck recruitment this population. Successful is also dependent upon food availability predation pressure mainly herring (Clupea harengus sprat (Sprattus sprattus L.). A 2-to 3-month delay period compared 20–30 years ago altered feeding susceptibility a way that may have exacerbated decline recruitment. Producing releasing larvae during spring would mimic recorded previous times coincide with peak copepod production. An evaluation 3...
