Effectiveness of Sea Cucumber Viscera Waste to Improve Reproductive Performance of Male Tiger Shrimp (Penaeus monodon)

Abstract

Tiger shrimp has received attention because of the high prices. However, sustainable cultivation of tiger shrimp is still hampered by the low quality of spermatozoa in male broodstock. Sea cucumbers are a type of invertebrate that is very useful because they have many viscera with almost the same nutritional content as fresh food. However, it has other advantages compared to other fresh feeds, namely it has a very high testosterone content so that it can be used to improve the quality and quantity of spermatozoa of male tiger prawns. The study aims to compare the influence between sea cucumber viscera and fresh squid as well as the combination of sea cucumber and squid viscera against the density of tiger shrimp spermatozoa (Penaeus monodon). Test animals used were 18 male tiger shrimp with an average weight of 80.93 g. Shrimp are kept in tanks with a volume of 1 ton, with a density of 3 broodstock/tank and 3 replications. Feeding was carried out with a frequency of 3 times a day and at a dose of 20% of biomass for 30 days. The test feed used consisted of 100% fresh squid feed as a control, a combination of 50% squid and 50% of sea cucumber viscera, and 100% of sea cucumber viscera. The administration of sea cucumber visceral waste in tiger shrimp tend to increase the quantity of spermatozoa tiger shrimp.
