Aspidoras fuscoguttatus individuals dug in the bottom d...

This study consisted of four treatments and three replications, namely the treatment without addition light (WL), green (G), blue (B) red (R). The grouper seeds used are 5-13 cm in size from Gondol Bali. results showed that fish fry measuring prefer compared to other light. A total 56.67% choose light, followed by as much 25.56%, 11.11% lowest was 6.67%. rearing container gave best growth respo...

Fish parasites are used to monitor long-term change in finfish grouper mariculture in Indonesia.

The fish were obtained from floating net cages of a commercially run mariculture facility that opened in 2001. The fauna was species rich, consisting of ten ecto- an...
