Growth and otolith ring deposition in Teleost larvae
Growth and otolith ring deposition were examined in the larvae of turbot, plaice, herring, and in salmon embryos. Larvae were reared under various light, temperature, and feeding regimes in order to measure the response of ring deposition to different sets of environmental cues. Ring deposition in h...
