Boldness and aggressiveness in early and late hatched three-spined sticklebacks Gasterosteus aculeatus.

abstract：:Marine fish are an irreplaceable resource, but are currently under threat through overfishing and climate change. To date, most of the emphasis has been on single stocks or populations of economic importance. However, commercially valuable species are embedded in assemblages of many species and there is only limited u...
