Abstract | Spawning patterns of inland silversides, Menidia beryllina, and tidewater silversides, Menidia peninsulae, were examined in the laboratory under several combinations of 'tidal' and diel light cycle cues. M. beryllina showed a high frequency of spawning throughout the day when held under constant conditions (24L: OD, current velocity 8 cm/sec) and when 'tidal' and diel light cycles were presented singly or in combination. Survival and growth of larval M. beryllina from the day of hatching through 16 days old was optimal at 15 parts per 1000 by weight. |
