KANDUNGAN VITAMIN C PADA OVARIUM IKAN LELE (Clarias gariepinus) SAAT SIKLUS REPRODUKSI
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

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.
