Salah satu terobosan untuk meningkatkan produksi udang adalah memanfaatkan laut dengan keramba jaring apung. Tujuan dari penelitian ini adalah untuk membandingkan komposisi kimia dari udang putih (Litopenaeus vannamei) dan daging udang windu (Penaeus monodon) yang dibudidayakan di keramba jaring apung. Hasil dalam penelitian ini menunjukkan bahwa daging udang putih memiliki kandungan protein dan abu yang lebih tinggi daripada daging udang windu. Komposisi langsung pada otot udang diatur oleh banyak faktor, termasuk spesies, tahap pertumbuhan, pakan dan musim.

Tilapia fish is a freshwater fish commodity that has the potential to be developed for fisheries business. Tilapia fish have many advantages such as easy breeding, fast-growing, and can survive at high salinity. To increase durability at high salinity it is necessary to prepare saline tilapia seeds produced from parentage that is tolerant to high salinity or through the salination process since the size of the seed. The purpose of this study was to determine the survival rate, absolute growth, and water quality during the adaptation period of increasing salinity of tilapia juvenile. The experimental design used was a completely randomized design with three replications. The salinity increase treatments used were A (1 ppt salinity), B (2 ppt salinity), C (3 ppt salinity), D (4 ppt salinity), and E (5 ppt salinity). The results showed the survival rate of tilapia seeds each treatment is treatment A (1 ppt) by 100%, treatment B (2 ppt) by 100%, treatment C (3 ppt) by 100%, treatment D (4 ppt) by 99.2%, and treatment E (5 ppt) by 98.6%. The results of each absolute growth of each treatment are treatment A (1 ppt) of 0.002 grams / day, treatment B (2 ppt) of 0.002 grams / day, treatment C (3 ppt) of 0.001 grams / day, treatment D (4 ppt) of 0.0007 grams / day, and treatment E (5 ppt) of 0.001 grams / day. It can be concluded that the adaptation of fish seeds at different salinities (1 ppt, 2 ppt, 3 ppt, 4, ppt, and 5 ppt) still shows a good survival rate, but the absolute growth of tilapia seeds on the adaptation of salinity increases of 4 ppt and 5 ppt has not been optimal.

Pemanfaatan sumberdaya perairan di teluk Hurun saat ini masih sangat potensial. Salah satu pemanfaatan sumberdaya perairan yaitu optimalisasi alat tangkap bubu lipat yang ekonomis dan ramah lingkungan. Penerapan alat tangkap ini diharapkan dapat memberikan gambaran potensi rajungan yang ada di teluk Hurun. Materi yang digunakan yaitu bubu lipat dan perlengkapan penangkapan lainnya. Penggunanaan alat tangkap bubu lipat menghasilkan tangkapan rajungan sebesar 88,98 kg (market size) dan 16,82 kg (under size) dengan jumlah yang diperolah masing-masing yaitu 916 ekor (market size) dan 358 ekor (under size).
