Abstract: | The effect of food density on the growth, survival, and swimming activity of plaice larvae (Pleuronectes platessa L.) was investigated under controlled laboratory conditions. Suboptimal food concentrations decrease the growth of the height of the body musculature relative to length, and increase the amount of time spent searching for food. Older larvae are able to withstand much longer periods without food than young larvae. On the basis of these experiments, it is suggested that food limitation in a larval plaice population is likely to result in a concave mortality curve. |
