Abstract

We briefly describe the localized abalone (Haliotis asinina) fishery in Siquijor Island, central Philippines and discussed the possible reasons of the sudden collapse in local trade and fishery. The lack of management system may have contributed to over-exploitation of abalone leading to closure in 2012. Prior to the collapse in 2012, abalone gatherers spent an average of 4.18±0.15 hours/day/site with catch-per-unit-effort (CPUE) of H. asinina ranged from 0.1 to 0.6 kg/person/hr with mean value of 0.25±0.03 (SE) kg/person/hr. Recommendations to revive and sustain the abalone fishery of Siquijor Island are also provided.   Keywords: abalone, fishery, overharvesting, Siquijor

Abstract

The objetive of research was to examine the effect of yeast cell Saccharomyces cereviciae on non-specific immune response of nile tilapia, Oreochromis niloticus. Juveniles weighing 31.83 g in average were cultured in five concrete tanks with a density of 30 fish per tank. The fish were fed pellet supplemented with yeast cell at five different doses (0, 10, 20, 30, 40 g/kg pellet) for three consecutive weeks as much as 4%/bb/day, twice daily. At the end of feeding, three fish from each tank were sampled to measure the immune parameters namely total leucocyte count and phagocytosis activity of phagocyte cells. Research results showed that after three weeks of feeding, total leucocyte and phagocytosis activity of fish fed pellet supplemented with yeast cells were significantly different as compared to those of control fish.  The highest total leucocyte and phagocytosis activity were achieved in fish fed pellet supplemented with 10 g of yeast cells/kg pellet.  It was concluded that the use of yeast cells for three weeks could enhance the nonspecific immune response of nile tilapia. Keywords: Saccharomyces cerreviciae, nonspecific immune response, total leucocyte count, phagocytosis activity, nile tilapia, Oreochromis niloticus

Abstract

The purpose of this study was to determine the current state of water quality in fish farming locations in the waters of Lake Tondano . Sampling points at each station are placed vertically in three predetermined points from the guard house to the front of the net.  The distance between one sampling  point to the next was ± 10 m. Water quality including physicals and chemicals parameters were analyzed at the Industrial Research Board of Manado. Sampling  point was made purposively as refers to the physiographic location in order to represent or describe these waters condition. This study was conducted for 2 weeks. Water sampling was done in three times, in the  morning, at noon, and in the evening. Direct measurement (in situ) was performed once a week that included DO, pH, temperature, and brightness, while the laboratory tests were conducted for 2 weeks which included phosphate, turbidity, Nitrite, Nitrate. Research results  showed that temperature, DO, pH, brightnes, phosphate, turbidity, nitrite, nitrate are still in good condition based on water quality standard stated in PP No.82 of 2001 . Keywords: Lake Tondano, water quality, chemical Parameter, physical Parameter

Abstract

Crustacean does not have adaptive immune system and mostly depends on innate or nonspecific immune response. This system can recognize and destroy foreign materials including pathogen.  The nonspecific immune responses of crustacean consist of cellular and humoral responses.  In cellular response, hemocyte plays an important role in body defenses to pathogen including virus, bacteria, fungi, and parasites. In humoral response, recognition of pathogen is mediated by protein and enzyme such as β-1,3-glucan-binding protein (BGBP),  lipopolysaccharide-binding protein (LPS-BP), peptidoglycan recognition protein, phenoloxydase enzime. Keywords: crustacean, nonspecific immune response, cellular responses, humoral response, protein, enzime

Abstract

Culture pattern of  seaweed Kappaphycus alvarezii like cultivation calender will improve the quality dan increase productionof seaweed.  This pattern can be arranged through examining seaweed growth and measuring waters quality. Culture technique used was long line where seaweed was tied at 100 cm from water surface.  Cultivation cycle was done twice a year using five frames measuring 3 x 3 x 2 m3 each and located at five observation stations.  Biophysical of water at each station was measured. Data of biophysic and seaweed growth were measured every two weeks for three months (from July to October 2013).  The present of epiphytes and ice-ice and seaweed pests was also observed.  Research result found the best season for cultivating seaweed at Nain Island was from July to early September while the evidence of ice-ice was high from September to October.  Biophysic and water quality around Nain Island was suitable of the growth of K. Alvarezii.   Keywords: seaweed, cultivation calender, growth, waters condition, ice-ice
