clupea harengus size

The relative contributions of the eye, pigmentation (melanophores), and gut contents to the lateral body areas of herring larvae, Clupea harengus L., were measured using a combination of photography and computer image analysis. Atlantic herring (Clupea harengus, Linneaus 1758), being one of the economically most important fish species, has been a subject of several studies on population structure [1–8].A relatively low level of genetic differentiation has been found among isolated local populations which may overlap geographically during feeding migrations [2–6,9–12]. Robust tests for the equality of variances. 89560 ) The influence of egg size on herring larvae (Clupea harengus L.) J. Cons. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. However, the two are best distinguished by the position of the pelvic fins, which are level with, or slightly in front of, the origin of the dorsal fin in the sprat but further back in the Baltic herring.

The purpose of the present study was twofold; first, to test and evaluate rigid grids as a method for selecting smaller individuals of herring (Clupea harengus) from the catch in a push-up trap, and secondly to analyze which abiotic and biotic factors were important for the selection.
