It is concluded that food limitation o ccurnng in different parts of the nursery may h ave led to growth differences in 1981 and 1982, and time of settlement, as shown by daily increm en t readings, proved to be the sam e as in populations in the main nursery ground.

The correlation analysis revealed a connection not only between the single parasitological and biochemical parameters but also within these groups, leading to the assumption that these may serve as links between the lowest and the highest levels of biological organisation.
Diel and habitat-dependent resource utilisation by deep-sea fishes at the Great Meteor seamount: niche overlap and support for the sound scattering layer interception hypothesis

The results are in support of the sound scattering layer interception hypothesis, which implies primarily pelagic food utilisation for bentho-pelagic fishes; increased habitat-dependent utilisation rates at locations of interception with the sound-scattering layer; sufficient resource partitioning among species in order to avoid competitive exclusion.

The Mediterranean may be regarded as a simulation model for a severely environmentally deteriorated, impoverished habitat, in which all or part of the intermediate host species have been depleted, enabling survival of the monoxenous parasite species only.
Developmental defects in pelagic fish embryos from the western Baltic

The potential of malformation rates in embryos of pelagic fish eggs as a tool for monitoring is considered and several reasons, including environmental and anthropogenic factors, for the occurrence of malformed embryos in pelagicFish eggs are discussed.
