Increase of temperature will change the timing of ecological events such as the spring plankton outburst so influencing the match or mismatch of larvae with their food supply and their predators.
The sense organs of teleost larvae are incomplete at hatching but sensory cells progressively recruit during development, and more complex feeding models incorporate energetic values of larva growth and food, nonrandom food distribution and search patterns of the larvae, and stochastic changes of variables.
The behavioural experiments described in this paper were carried out to complement earlier physiological work on the acoustico-lateralis system of the clupeid fishes and suggested that the signals arising from the inner ear and the neuromasts of the lateral line are used in conjunction to provide information about direction and range.
Present evidence suggests that pressure is important in triggering the response and probably in measuring the strength of the stimulus and a vector such as particle velocity provides the directional information used in the response.
The herring has an elaborate racial system closely linked to its spawning habits and has a complex camouflage system based on silvery layers of guanine crystals in the skin, a specialised retina, and a very complex acoustico-lateralis system linked to the swimbladder.
