The high frequency of infected males in shoals suggests that most infected males remained in shoals during the breeding season.
As the stock declines, it typically forms fewer shoals, albeit comparable in size to those which obtained previously, but distributed over a reduced area.
Rather, their enterprise, like that of the other sciences, runs aground on the shoals of epistemology.
514 formed in open-marine, wave-swept environments, often associated with grainstone shoals, and occur mainly in bioherms set within a stratigraphic position consistent with accommodation increase and sea-level rise.
However, in the present study we focused on individual responses and interactions associated with avoidance behaviour, and studies on shoaling behaviour and parasites in fish require future work.
Furthermore, anchovy, like other small pelagic fish, form tight shoals in defence against predation.
There is no evidence that dolphins have any serious effect on fish shoals or on fishing gear.
A short time later he appeared on television applauding the fact that he had received shoals of supporting letters from all over the country.
