A study was conducted to obtain a measure of the potency of some
potential and commercially used feeding attractants for Penaeus monodon
Fabricius. Behavioural trials monitoring the feeding response of the
shrimp were used to gauge the attractant qualities of the substances. A
growth trial recording the feed intake, feed assimilation, growth, food
conversion and survival rates of the shrimp was used to assess further
the feeding stimulant properties of the substances.
Replicate groups of juvenile shrimp were fed semi-purified diets
containing 1·5% by weight of a range of potential feeding attractants.
In the behavioural trial, diets containing taurine and a yeast extract
were found to be significantly preferred to the control and all other
diets. However, none of the substances appeared to act as potent feeding
stimulants, producing statistically similar feed intake and assimilation
rates to the control diet. However, taurine and an amino acid mixture
designed to mimic a clam extract promoted the best performance of the
attractants tested in terms of growth rate and feeding efficiency.
Overall, the behavioural response of the shrimp to the feeding
attractants was found to show similarities to the effects of attractant
supplementation of feed on subsequent ongrowing performance, but not
