Eish shrimp respond to pheromone - based feeding attractants

摘要

The chemical communicators pheromones can be used to induce increased feeding activity in a range of farmed species. Preliminary commercial testing with pheromone feeding stimulants sprayed onto the surface of water prior to feeding found better feedutilization in fish and better water quality. Pheromone applications also produced shrimp that were 30% larger than the control shrimp and had a significantly faster rate of growth. The development of new and effective feeding attractants targeted at theexpanding aquaculture industry may have an important role in increasing the feeding activity of many fish and shellfish species, reducing the waste that enters the environment and also permitting more widespread use of feeds derived from more-sustainable protein sources.
