KARAKTERISTIK HABITAT DAN TINGKAT KEMATANGAN GONAD KEPITING KELAPA ( Birgus latro ) DI PULAU UTA, PROPINSI MALUKU UTARA
Ringkasan: Coconut crab
(Birgus latro) is one of the species of crustaceans that eco-nomically
valuable. The research aimed to investigate habitat characteristics and go-nad
maturity of Coconut crabs (Birgus la-tro ) in Uta Island, North Mollucas.
Sam-pling was conducted through cruising su-rvey from May to September 2012,
while parameters examined to the habitat cha-racteristics and reproductive
aspects were physical-chemical, gonad maturity, and ve-getation existence.
Habitat characteristics were assessed using Cluster Analysis. Re-sult showed
that length and weight rela-tionship of male crabs was W = 1.93 (CP + r), while
the female was 1.17 W = 1.97 (CP + r) 0.97. During the observation, it sho-wed
that mature gonad occurred in all ca-tching time indicating that it didn’t
occur simultaneously on the broodstock. The sma-llest crabs were found 65.44 mm
in length (CP + r). There was no significant diffe-rent of sex ratio between
males and fema-les (1:1). Disparity of habitat characteris-tics in each station
doesn’t affect to the ca-tch, both the quantity and level of gonad maturity.
Habitat conditions at all stations strongly supported their activities to live sustainably.
