EFEKTIVITAS PEMBERIAN BEBERAPA BAHAN DAN DOSIS ANESTESI PADA PRAKONDISI KERANG AIR TAWAR (ANODONTA WOODIANA)

The main problem on freshwater mussel culture is the high mortality during implantation process. Freshwater mussel that will be implanted for cultivation need to be conditioned in a state that facilitates the opening of its shell. Because lack of information on the use of anesthesia in the cultivation of freshwater mussel, these principles can be applied is the principle which has been successfully applied in the cultivation of sea mussel. This study aims to determine the best responses to materials anesthetic and dose in precondition of Anodonta woodiana which held in Freshwater Aquaculture Center (BBAT) Tatelu in District Dimembe, Minahasa Regency. The study was designed by using completely randomized design factorial pattern with two factors: materials anesthetic and dose. Material anesthetic factor has 4 degree such as menthol oil, clove oil, nutmeg oiland lemongrass oil. Dose has 3 degree such as 1,5 ml, 2,5 ml and 3,5 ml. Each treatment was repeated 3 times. The results showed that nutmeg oildose of2,5 ml/L more effective for precondition (respons, relaxation time, recovery and mortality rate) than dose of 1,5 ml/l and 3,5 ml/L and than another materials anasthethic (menthol oil, clove oil, and lemongrass oil)

POLA PERTUMBUHAN KERANG MUTIARA Pinctada margaritifera DI PERAIRAN SULAWESI UTARA

The pearl oyster Pinctada margaritifera (Linnaeus, 1758) or black lip pearl oyster is a marinebivalves with important economic value. This Indo-Pacific species is found in abundance in the waters of North Sulawesi, but cultivation activities have not been optimized. Growth information is important for aquaculture activities because it is a useful indicator to determine the health of pearl oysters and environmental suitability (Moussa, 2013). The purpose of this study was to determine the growth pattern of P. margaritifera pearl shells in the waters of North Sulawesi. Species P. margaritifera were collected at a depth of 2-20 m in the waters of North Minahasa Bahoi, Arakan waters South Minahasa and Talengen waters Sangihe Islands, North Sulawesi Province. The morphometric parameters observed included shell length (PC), shell height (TC), shell thickness (tC), and total weight (BT). The relationship between length, height, shell thickness and total weight was analyzed by regression equation. Morphometric measurements of P. margaritifera showed average shell length (PC) of 95.26 mm (Arakan waters), 81.15 mm (Talengen waters) and 70.19 mm (Bahoi waters). The growth pattern of P. margaritifera in the waters of Bahoi, Arakan and Talengen, North Sulawesi Province was allometric negative. This means that the increase in length, height and thickness of the shell is faster than the total weight.Kerang mutiara Pinctada margaritifera (Linnaeus, 1758) atau black lip pearl oyster merupakan bivalvia laut yang bernilai ekonomis penting. Species Indo-Pasific ini ditemukan melimpah di perairan Sulawesi Utara, namun kegiatan budidaya belum dioptimalkan. Informasi pertumbuhan penting untuk kegiatan budidaya karena merupakan indikator yang berguna untuk mengetahui kesehatan kerang mutiara dan kesesuaian lingkungan (Moussa, 2013). Tujuan penelitian ini untuk menentukan pola pertumbuhan kerang mutiara P. margaritifera di perairan Sulawesi Utara. Species P. margaritifera dikumpulkan pada kedalaman 2-20 m di perairan Bahoi Minahasa Utara, perairan Arakan Minahasa Selatan dan perairan Talengen Kepulauan Sangihe Provinsi Sulawesi Utara. Parameter morfometrik yang diamati meliputi panjang cangkang (PC), tinggi cangkang (TC), tebal cangkang (tC), dan berat total (BT).

KESESUAIAN LAHAN BUDIDAYA LAUT DI PERAIRAN KABUPATEN BOLAANG MONGONDOW SELATAN, SULAWESI UTARA

Penelitian dilakukan untuk mengkaji tingkat kesesuaian lahan budidaya laut, khususnya budidaya rumput laut dan budidaya ikan di Kurungan Jaring Apung (KJA) di perairan Kabupaten Bolaang Mongondow Selatan, Provinsi Sulawesi Utara. Penentuan stasiun pengambilan sampel dilakukan berdasarkan identifikasi adanya aktivitas budidaya rumput laut dan budidaya ikan pada KJA di lokasi tersebut. Lima stasiun pengamatan yakni lokasi budidaya rumput laut desa Matandoi, dan lokasi budidaya ikan dalam KJA di desa Deaga, Torosik, Matandoi dan Pinalantungan. Pada tiap stasiun ditentukan satu titik pengambilan sampel air untuk pengukuran parameter kualitas air, serta aspek fisik lain seperti kecepatan arus dan beda pasang-surut air laut. Parameter kualitas air seperti amoniak, pH, suhu, nitrit dan turbiditas diukur menggunakan Water Test Kit AYI-10 in ScienPro, sementara salinitas dan oksigen terlarut (DO) diukur menggunakan Water Tester Horiba. Data yang diperoleh ditabulasi dan ditampilkan dalam histogram. Untuk menentukan tingkat kesesuaian lahan, data dibandingkan dengan baku mutu persyaratan untuk lokasi budidaya rumput laut dan budidaya ikan di KJA. Hasil penelitian menunjukkan bahwa perairan desa Matandoi sesuai untuk lokasi budidaya rumput laut. Perairan desa Pinalantungan, desa Torosik, dan desa Matandoi sesuai untuk lokasi budidaya ikan di KJA, sedangkan perairan desa Deaga kurang sesuai untuk lokasi budidaya KJA. Kata kunci: kesesuaian lahan, budidaya, rumput laut, KJA, Bolaang Mongondow Selatan.   This study was aimed to study the suitability level of waters in South Bolaang Mongondow Regency, North Sulawesi Province, for seaweed culture and fish culture in floating net cage (KJA). The stations for water sampling were appointed based on the occurrence of the seaweed culture and finfish culture in KJA in the area. Five stations were appointed, where one station representing seaweed culture area (Matandoi village waters), while four stations representing the floating net cage culture areas (Deaga, Torosik, Matandoi and Pinalantungan village waters). At each station, one point was appointed for sampling of waters for the measurement of water quality parameters and for assessment of other physical features of waters body such as, current velocity, wave height and tide level. The other water quality parameters such as, ammonia, pH, temperature, nitrite, and turbidity were measured using Water Test Kit AYI-10 in ScienPro, whereas dissolve oxygen (DO) and salinity were measured using Horiba Water Tester. The collected data were then tabulated and presented in histogram. To analyze the level of the suitability of the area for seaweed culture and floating net cage culture, the obtained data were compared to the standard water quality for the location of seaweed culture and floating net cage culture. The results show that, the territorial waters of Matandoi village is suitable for seaweed culture area. The territorial waters of Pinalantungan village, Torosik village and Matandoi village are suitable for floating net cage culture area, while territorial waters of Deaga village is less-suitable for floating net cage culture area.
