Karakteristik Kualitas Air dan Kinerja Produksi Udang Vaname Litopenaeus vannamei di Tambak Semi Intensif, Lampung Selatan

Abstract

Kualitas air budidaya udang vaname yang buruk dapat menghambat pertumbuhan, memicu penyakit, dan menyebabkan kematian. Proyek akhir ini bertujuan mengevaluasi karakteristik kualitas air dan kinerja produksi udang vaname di tambak semi intensif, Lampung Selatan. Metode yang digunakan meliputi pemeliharaan udang selama 103 hari di kolam C6 dan C7 berukuran 2500 m² dengan padat tebar 67 ekor/m², pengukuran parameter kualitas air, dan sampling pertumbuhan udang. Hasil menunjukkan perbedaan signifikan salinitas antara kolam C6 dan C7, serta kondisi Total Organic Matter (TOM) dan total Vibrio sp. yang tidak optimal untuk budidaya udang. Kedua kolam mengalami serangan Acute Hepatopancreatic Necrosis Disease (AHPND). Kinerja produksi menunjukkan Average Daily Gain (ADG) yang baik (0,3-0,31 g/hari), namun Sintasan (SR) rendah (35,83-51,43%) dan Food Conversion Ratio (FCR) tinggi (1,80-1,88 kg). Kualitas air dan kinerja produksi udang vaname di tambak semi intensif, Lampung Selatan menunjukkan hasil kurang optimal.

Poor water quality in vaname shrimp farming can inhibit growth, trigger disease, and cause mortality. This study aims to evaluate water quality characteristics and production performance of vaname shrimp in semi-intensive farm, South Lampung. The methods used included 103 days of culture in pools C6 and C7 measuring 2500 m² with a stocking density of 67 fish/m², measurement of water quality parameters, and sampling of shrimp growth. Results showed significant differences in salinity between pools C6 and C7, as well as conditions of Total Organic Matter (TOM) and total Vibrio sp. that were not optimal for shrimp culture. Both pools experienced Acute Hepatopancreatic Necrosis Disease (AHPND). Production performance showed good Average Daily Gain (ADG) (0.3-0.31 g/day), but low Survival Rate (SR) (35.83-51.43%) and high Food Conversion Ratio (FCR) (1.80-1.88 kg). Water quality and production performance of vaname shrimp in semi-intensive farm, South Lampung showed not optimal results.
