| Summary: | Kajian 1m bertujuan untuk mengurangkan masalah kematian dan
meningkatkan kadar hidup anak ikan kerapu (Epinephelus sp.) semasa peringkat awal
temakan di sangkar. Keberkesanan beberapa agen kemoterapeutik iaitu NFSSodium,
Kloramfenikol, Oksitetrasiklin, Diameton, Nitrofurazon, Furazolidon,
FuranaxR
, Asid Oksolinik dan Prefuran telah dikaji, melalui kaedah pemberian
melalui makanan dan kaedah rendaman. Kesan bahan-bahan rawatan ini dan kaedah
rawatan ke atas kadar hidup dan pertumbuhan telah ditentukan. Keputusan
menunjukkan bahawa NFS-Sodium dan Kloramfenikol adalah berkesan dalam
mengawal vibriosis di dalam sistem kultur tertutup tetapi tidak berkesan di dalam
sistem sangkar di mana mortaliti yang direkodkan melebihi 85% bagi semua bahan
rawatan.
This study is aimed at reducing mortality or increasing the survival rate of
grouper fingerlings Epinephelus sp. during the initial cage culture period. The
effectiveness of chemotherapeutic agents, namely NFS-Sodium, Chloramphenicol,
Oxytetracycline, Diameton, Nitrofurazon, Furazolidon, Furanax R, Oxolinic Acid and
Prefuran were evaluated both by oral administration and immersion trials. The effects
of these chemicals and treatment methods on the growth and survival rate were
determined. Results indicated that NFS-Sodium and Chloramphenicol were effective
in controlling vibriosis in a closed culture system but were ineffective in cage system
where mortality recorded exceeded 85%, irrespective oftreatments.
