Aquaculture – Decapod crustacean – Eyestalk ablation.
Assignment 2 – Eyestalk ablation In the culture of decapod crustaceans, eyestalk ablation has been employed to induce ovarian maturation and spawning with varying success in many crustacean species. It can also be used to shorten the moult interval and to mobilise nutrients. This procedure is known to induce hormonal imbalance, stress and depletion of reserve materials, which often results in high mortality. 1) Describe the effects of eyestalk ablation in decapod crustaceans. 2) What are the causes of these effects? 3) What problems are encountered when eyestalk ablation is used to induce maturation and spawning, rather than allowing these events to proceed naturally? 4) Is there any evidence that this procedure is affecting public opinion and marketing? Are there any alternatives (potential or real) which are less stressful, produce less Kayla 3000 word are 11 double-spaced pages *words
