Abstract

This study was aimed to determine the effect of the dilution ratio of sperm with optimal NaCl and fructose on the motility of the catfish, Clarias sp., spermatozoa, fertility and hatchability of eggs. Catfish used in this study consisted of one parent pairs (male and female weight of 1000 grams weight of 1500 g). NaCl and fructose solution were diluted with aquabidest. The observation was conducted on the motility of spermatozoa, fertility and hatchability of eggs. The experimental design used completely randomized design (CRD). Dilution ratio is 1: 0, 1, 20, 1: 40, 1; 60, 1: 80, and 1: 100 with replicated 3 times. Observations were carried out soon after the sperm mixed with diluents. Fertility occurred 12 hours after fertilization. Egg hatchability was observed after fertilization. The results showed that the ratio of dilution gave significant effect on the sperm motility, fertility and hatchability of the eggs. This research found that the dilution ratio 1: 60 was the best treatment with the average sperm motility of 96. 66%, fertility of 71, 66 5% and egg hatchability of 70%.

Abstract

Good quality carp seed supply in relation to number, time, price and location is a crucial factor for the success of the fish cultivation. To ensure the availability of fish seed under these requirements, this study was technically directed to increase the fertility rate, the hatchability rte and the survival of larvae and post larvae. This study was aimed to find good substrates for spawning and egg hatching of the common carp, Cyprinus carpio L. Were used at Sugar Palm Fiber and Hydrilla sp. as substrates for the egg attachment. For this, males and females of 1:1 weight ratio were put into the spawning pond. Eggs attached to both susbtrate types were counted. Water quality parameters, such as temperature, dissolved oxygen and pH, were also recorded. Results showed that common carps had higher preference to Hydrilla sp. to attach their eggs than to Sugar Palm Fiber (kakaban). Egg hatching is also higher in Hydrilla sp than in Sugar Palm Fiber (kakaban), even though the degree of conception, however were not significantly different.

Abstract

Vitamin C content in the ovarium of African Catfish (Clarias gariepinus) during reproductive cycle was investigated. One hundred twenty samples of females covering different stages of reproductive cycle were collected from fresh water ponds. The fishes were sacrifized and the ovarium were collected for analysis of gonad maturation stage (TKG), oocyt structure and vitamin C content in the ovarium.  Results indicated that average of vitamin C content of ovarium at stage I was 74.33mg/g (wet weight). The maximum content was found in stage III at level of 155.98mg/g (wet weight) and afterwards in the next stage vitamin C content decreased. The maximum of oocyt stadium 3 (oocyt vitelogenesis) was also found at this stage III. The findings indicate that vitamin C has a role in the reproductive cycle of catfish and its content is related to ovarium development and oogenesis.

Abstract

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. Keywords: area suitability, culture, seaweed, floating net cage, South Bolaang Mongondow.
