Herring, unlike most other clupeoids, are total spawners with a group-synchronous ovarian organization (Murua & Saborido-Rey, 2003).
The study area, that is the NE Baltic Sea, is also inhabited by very abundant two other clupeoid species: spring herring and sprat, which both can induce density-dependent effects (Casini et al.
Sardine and other clupeoids respond to oceanographic conditions, and, in the absence of predators and competitors, tend to aggregate near their prey in monospecific, epipelagic (ca.
Like other clupeoids, sardine inflate their swim bladders by swallowing air at the surface and by forcing it from the stomach through the pneumatic duct into the swim bladder.
Ephemeral spawning aggregations in the Mediterranean sardine, Sardina pilchardus: a comparison with other multiple-spawning clupeoids.
Within the coastal zone are found the big-eye scads, anchovies, clupeoids, and half-beaks.
by beach seines, handlines, and gill nets, while the smaller clupeoids may continue to be largely unexploited other than for tuna baitfish.
Such large changes in catch composition over the history of a fishery appear to be a characteristic of small pelagic clupeoid fisheries where declines in abundance of one species are offset by partial replacement by other species.
This dependency on clupeoids, particularly Atlantic menhaden, has been well-documented throughout the range of striped bass (Walter et al.
This study outlines the importance of clupeoid fishes to striped bass winter production and also shows that predation may be exerting pressure on one of their dominant prey, the Atlantic menhaden.
Because trawling activities during PBSs were aimed at small pelagic clupeoids, it was not possible to use CPUE data from these cruises to analyze spatial patterns in juvenile snoek abundance.
Onshore-offshore distribution (between 5- and 150-m isobaths) of juveniles is determined largely by prey availability and includes a seasonal inshore migration in autumn in response to clupeoid recruitment.
