Explain the match/mismatch theory

Basicly if cod larvae spawn at the same time as bloom there is a match and good conditions for the larvae, if not there is a mismatch and bad conditions. It is often temperature that determines when the bloom arrives and therefor if there is match or mismatch First curve is fish eggs Second curve fish larvae Larvael food – third curve When the larvae overlap with food – match. Otherwise mismatch. Match gives good conditions for cods. Bottom up explnation for cod survival. Early feeding conditions are important for the cod larvae. Even with good feedconditions a lot die - predation and canibalism. But good cod years can be explained by match. Fish arent that influeneced by temp – but zooplankton really deped on temp. Cold spring – mismatch. Very hot spring – mismatch. You want the bloom on exactly the right time.
