摘要：Nusa Penida island is one of center for seaweed culture in
Bali province. Seaweed that cultured is Euchema spinosum and Euchema
cottoni spread around coastal. There also found wild seaweed, such as
Ulva sp and Gracillaria sp. Abalone (H. squamata) is one of kind
Mollusca which high economic value, but abalone cultured is not yet
develop in Nusa Penida island, although this island have high potency for
developing abalone culture. Abalone culture needs seaweeds as a diet. The
abundance of seaweeds as abalon diet is important for developing abalon
culture in Nusa Penida Island in the future. The aim of this research was to
asses the potency of seaweeds as diet for developing abalone culture in
Nusa Penida island. Research was done in Batununggul village, Nusa
Penida Island. Experimental design was used Completely Randomized
Design (CRD) with 3 treatments and 3 replications. The treatments were
used different seaweeds as diet for abalone culture: (DG=Diet Gracillaria
sp, DS=Diet Spinosum sp. and DU=Diet Ulva sp.). Abalon were cultured
for 4 months by feeding the diet at satiation. Data analysis was used
analysis varian (Anova) with SPSS. 16. The result showed abalon fed with
Gracillaria sp (DG) at 4.73 g was the highest growth by 4.73 g, followed
DU by 3.93 g and DS by 3.43 g. Meanwhile the abalon shell length fed
with Gracillaria sp (DG) was the highest growth by 6.55 mm, followed
DU by 5.97 mm and DS by 5.60 mm. Based on variant analysis showed
growth performance (length shell and weight) abalon, all treatments were
not significantly different (P>0.05). The conclusion this research, the three
species of seaweed can be used as diet for abalone culture. These seaweeds
have same potency as diet for developing abalone culture in Nusa Penida
Island.
