Abstract

Vannamei shrimp (Litopenaeus vannamei) holds significant economic importance in Shrimponesia as a prominent shrimp commodity. The post-larval stage often encounters challenges, primarily due to the shrimp's limited ability to adapt and survive in a new environment. Stocking density is a crucial factor influencing the growth and production performance of vannamei shrimp culture. This study aims to assess the optimal stocking density for achieving optimal growth and survival in L. vannamei. A 40-day maintenance trial was conducted at UD Mina Rahayu Kalianda to investigate the impact of different stocking densities on water quality in the maintenance media. The study utilized containers with varying stocking densities: treatment A (1 shrimp/L), treatment B (1.5 shrimp/L), and treatment C (2 shrimp/L), each with three replications. The findings revealed survival rates (SR) of 83.33% for treatment A, 62.78% for treatment B, and 58.33% for treatment C. Mean Body Weight (MBW) values were recorded as 1.2592 g/shrimp for treatment A, 1.1216 g/shrimp for treatment B, and 0.7728 g/shrimp for treatment C. Average Daily Growth (ADG) results showed 0.0313 g/shrimp for treatment A, 0.0279 g/shrimp for treatment B, and 0.0192 g/shrimp for treatment C. Based on the study, the recommended stocking density for white vannamei shrimp is 40 shrimp/L, demonstrating improved growth and survival rates for this species.

Abstract

Permasalahan yang dihadapi oleh mitra Ulam Gading Mas adalah harga pakan yang dari tahun ke tahun meningkat, sehingga meningkatkan biaya produksi. Sementara daya beli masyarakan akan menurun jika harga jual ikan gurame dinaikkan, mengingat kondisi pandemi yang berdampak pada ekonomi. Di sisi lain, pemerintah telah menggalakkan penanaman indigofera di Pringsewu sebagai pakan ternak. Saat ini masyarakat belum mengerti pemanfaatan tanaman tersebut untuk pakan ikan. Diseminasi dan bimbingan teknis aplikasi teknologi hidrolisis tepung daun indigofera sebagai bahan baku pakan perlu dilakukan. Bahan yang mudah didapatkan dan murah, namun dapat meningkatkan pertumbuhan ikan ketika disuplementasikan ke pakan. Pemanfaatan daun indigofera dengan aplikasi teknologi ini berpeluang besar untuk meningkatkan produktivitas budidaya karena dapat meningkatkan pertumbuhan ikan dan harga pakan yang dihasilkan lebih ekonomis. Program pengabdian masyarakat ini meningkatkan pemahaman dan keterampilan pembuatan pakan serta mampu mengapikasikan teknologi hidrolisis enzim selulose pada tepung daun indigofera yang akan disuplementasikan pada pakan ikan gurame. Kata kunci: hidrolisat, tepung daun indigofera, pakan Ikan gurame
