Abstract

Dalam penelitian ini, pengaruh suplementasi larva lalat tantara hitam kering yang mengandung lesitin kedelai (SBL) dievaluasi terhadap performa pertumbuhan, parameter biokimia, dan retensi nutrisi ikan mas (Cyprinus carpio L.). Tiga jenis pakan diuji: pakan DBSFL 20% DBSFLD tanpa tepung ikan dan SBL, pakan tanpa memasukkan tepung ikan dan dengan memasukkan SBL, dan pakan kontrol (CONT; 20% tepung ikan). Studi pemberian pakan dilakukan selama empat minggu. Tingkat pertumbuhan spesifik ikan yang diberi pakan DBSFL (9,48 ± 0,05b) dan SBLD (9,47 ± 0,08b) secara signifikan lebih rendah daripada ikan yang diberi pakan CONT (9,79 ± 0,15 a). Tak satu pun dari perlakuan cukup mengubah retensi protein ikan. Namun, ada perbedaan substansial antara kelompok SBL dan CONT dalam hal retensi lipid. Meskipun kadar trigliserida plasma tidak berbeda nyata 8 jam setelah pemberian pakan, ikan yang diberi makan SBLD cenderung memiliki kadar TG terendah. Kesimpulannya, pemberian pakan DBSFL 20% berdampak negatif pada konsumsi lipid, dan efek negatif ini tidak dapat dikembalikan dengan pemberian SBL; karenanya, meningkatkan kadar lesitin kedelai dalam pakan DBSFL mungkin bukan strategi yang layak. Untuk menjelaskan mekanisme kerja pemanfaatan lipid yang buruk oleh makanan DBSFL dan penawarnya, diperlukan penelitian tambahan.
POTENSI DAN KADAR NUTRISI IKAN RUCAH YANG DIDARATKAN DI PANTAI AMPENAN, NUSA TENGGARA BARAT Wastu Ayu Diamahesa; Bagus Dwi Hari Setyono; Rangga Idris Affandi; Damai Diniariwisan

Abstract

Penelitian ini berfokus pada ikan rucah, hasil samping dari kegiatan penangkapan ikan yang masih menjadi bagian signifikan dari tangkapan nelayan di Pantai Ampenan, Mataram, Nusa Tenggara Barat. Sayangnya, seringkali ikan rucah ini tidak dimanfaatkan secara optimal, sehingga berpotensi menjadi limbah dan menimbulkan risiko pencemaran lingkungan. Penelitian ini bertujuan untuk mengevaluasi kualitas ikan rucah yang didaratkan di Pantai Ampenan, Mataram, dengan fokus pada analisis kadar nutrisi. Metode purposive sampling digunakan dalam penelitian ini, dengan analisis yang bersifat deskriptif. Sampel ikan yang diperoleh dari nelayan dianalisis untuk menentukan kadar protein, lemak, dan air. Hasil analisis menunjukkan bahwa kadar protein pada ikan rucah yang didaratkan di Pantai Ampenan, Mataram berkisar antara 71,52% hingga 72,34% untuk fillet, dan 54,80% hingga 70,60% untuk seluruh tubuh. Sedangkan kadar lemak ikan rucah bervariasi antara 0,65% hingga 4,23% untuk fillet, dan 0,96% hingga 6,31% untuk seluruh tubuh.Temuan ini mengindikasikan bahwa ikan rucah memiliki potensi nutrisi yang signifikan, terutama dalam hal kadar protein. Evaluasi ini memberikan wawasan yang berharga terkait potensi pemanfaatan ikan rucah sebagai sumber nutrisi yang bernilai, serta menciptakan pemahaman lebih lanjut terkait dampak lingkungan dan manfaat ekonomis yang dapat diperoleh dari optimalisasi pemanfaatan ikan ini.

Abstract

This article discusses the nutritional requirements, particularly protein and lipid, in mud crabs (Scylla spp.). Mud crabs are one of the seafood types with a continuously increasing global demand. This literature review aims to provide an overview of the protein and lipid requirements in three mud crab species, namely Scylla paramamosain, Scylla olivacea, and Scylla serrata, which are the focus of aquaculture research. The research method involves comprehensive and systematic literature searches using predefined keywords. The findings indicate that protein and lipid requirements can vary depending on the growth phase, water temperature, and other environmental conditions. During the early growth phases, such as the larval and juvenile stages, mud crabs require higher protein levels to support rapid growth and optimal organism development. However, as they reach adulthood, protein requirements tend to decrease alongside metabolic changes and reproductive activity. Several studies have identified protein and lipid requirements for various mud crab species. The results show that optimal protein and lipid levels may vary depending on the species and growth stage of mud crabs. Therefore, this information is crucial for the development of suitable artificial feeds to effectively support the growth and health of mud crabs. In conclusion, this research provides important insights into the nutritional requirements of mud crabs and can serve as a guide for farmers to formulate feeds tailored to the daily needs of the crabs. Thus, this article makes a valuable contribution to the development of sustainable and efficient mud crab aquaculture industries.

Abstract

The development of Ekas Bay as a center for integrated aquaculture activities, particularly through the Floating Net Cage (FNC) system, can impact phytoplankton abundance and water fertility. Phytoplankton, a type of plankton capable of photosynthesis, acts as a primary producer and serves as a key food source for fish and lobsters. The presence of phytoplankton is closely related to the fertility levels of waters designated for marine aquaculture. This study aims to determine the composition and abundance of phytoplankton in the waters of Ekas Bay. The research employed purposive sampling, collecting phytoplankton samples from five predetermined stations: three points near FNCs and two points distant from the FNC area. The results indicate that the plankton abundance in the waters of Ekas Bay is categorized as mesotrophic. The highest phytoplankton abundance was recorded at Station V with 9,523 cells/L, while the lowest was at Station II with 2,150 cells/L. Based on station characteristics, Station V is the farthest point from FNCs, whereas Station II contains a high concentration of FNCs. The community structure, as indicated by the H’, E, and D values, suggests that the waters of Ekas Bay remain in a stable condition. Phytoplankton from the class Bacillariophyta was the most commonly found, although no specific genus was dominant.
