Abstract

Panulirus penicillatus reserve is quite abundant in Labangka waters, southern Sumbawa (Indonesia). Uropod is used to observe the lobster sex namely open uropod is female, and closed uropod (bud) is male. Measurement of female lobster to obtain data on carapace, body, gonad, and egg. The study aim is to determine the carapace length at first mature of gonad(CLm). The female Labangka spiny lobster CLmat 62.57 mm which was weight 217 grams. The egg diameter is 273 m and fecundity 41,701 eggs, so that the gonad's maturity level (GML)was IV. Whereas, male lobster reaches GML IV at CLm 67.75 mm and body weight 273 grams. It can be estimated that each 1 mm of lobster carapace contains 666-667 eggs, or 192-193 eggs / gram of lobster body. The study results provide the benefits and ease of effective and efficient for lobster hatchery units to select prospective bloodstock lobster.
