Abstract

Fish have strong temperature preferences to spawning. Several species of marine fish are known to spawn only at favorable water temperature that is known to trigger the process of spawning activities. The annually recurring events of life-cycle such as timing of spawning can provide particularly sensitive indicators of changes in climatic change. Many evidences of phenological changes are now available for terrestrial organisms. There is now ample evidence of the effects of climatic change on various biota over the last decades, but the literature on the effects of climate on phenological aspects in marine ecosystems is meager.
