Abstract

Ikan kakap putih (Lates calcarifer) merupakan spesies budidaya penting yang berasal dari wilayah Indo-Pasifik Barat yang dapat dibudidayakan baik di kolam serta di keramba dan merupakan ikan dengan nilai ekonomis tinggi, baik dalam pemenuhan kebutuhan konsumsi di dalam negeri maupun untuk tujuan ekspor. Tujuan dilaksanakannya penelitian ini yaitu untuk mengkaji aspek-aspek teknis dalam budidaya perikanan khususnya teknik pendederan benih kakap putih. Penelitian ini merupakan jenis penelitian kualitatif dengan pendekatan deskriptif. Metode pengumpulan data yaitu dengan observasi, wawancara dan dokumentasi. Penelitian ini dilaksanakan pada bulan Januari-Maret 2022 yang berlokasi di Divisi Ikan Laut, Unit Pendederan Benih Ikan Laut, Balai Perikanan Budidaya Air Payau (BPBAP) Takalar, Kabupaten Takalar Provinsi Sulawesi Selatan. Hasil penelitian menunjukkan bahwa proses pendederan benih kakap putih (L. calcarifer) terdiri atas beberapa tahap yaitu persiapan bak, manajemen kualitas air, pemberian pakan, grading dan seleksi, pemanenan, pengepakan, serta transportasi benih.

Abstract

One mitigation strategy that can be implemented for shrimp infected with vibriosis is the administration of immunostimulants. However, the use of commercial immunostimulants derived from chemical compounds is a cause for concern due to potential long-term adverse effects. This study focuses on gill tissue damage, survival rates, and water quality. The objective of this study is to determine the effect of administering natural immunostimulants from S. obtusa on gill tissue damage, survival rate, and water quality in vanamei shrimp infected with the bacteria V. parahaemolyticus. The study was conducted using vanamei shrimp samples divided into 7 treatments, each containing 10 shrimp. The treatments consisted of administering S. obtusa immunostimulant at 300 ppm (A), 400 ppm (B), 500 ppm (C), 600 ppm (D), 700 ppm (E), positive control (K+) as a treatment without S. obtusa immunostimulant administered and infected with V. parahaemolyticus, and a negative control (K-) as normal shrimp. The lowest level of lamella fusion damage was 5%, and the highest was 30%. The lowest level of lamella fusion damage was 5%, and the highest was 70%. The highest survival rate was 90.00%, and the lowest was 56.67%. The results indicate that mitigation efforts using the immunostimulant extract of S. obtusa from Sidoarjo, East Java, have a significant effect
