Tidal lowland is a potential land for aquaculture, however it should be manage intensively in order to give a good and sustainable contribution for society. Tidal fenomenon and rainfall will interacted with water quantity and quality which will used as fish media culture. Fish need optimal water to support its growth and survival. Based on measure and water analysis in two locations, at Mulyasari village, Tanjung Lago District, Banyuasin Regency, South Sumatera, tidal and rainfall gave effect to physical, chemical and biological of water quality and quantity. Related to the change of weather where in the second year (2016) the dry season was longer than rainy season since 2015,the rainfall was only about 200 mm- 310 mm/month. The lower of rainfall effected to the water level in canals and influent the brightness and turbidity, sea intrution that brought salinity about 5-15 ppt in the water.Acidity was also decline about 3.5-5 with ammonia- free reached 0.25 mg/L. Nitrate and nitrite were in common such a natural water condition, yet pyrite oxidized that caused the water and land tobe reddish yellow and looked like greasy in the surface. These condition would be harmfull for fish. The tidal and rainfall was also effect plankton abundance. The data shows that fitoplankton and zooplankton were higher in the canals than in the pond.

Grouper fish has a fairly high economic value, especially in Asiancountries, namely Hong Kong, Singapore, Taiwan and China. High marketdemand. On aquaculture, is one important component of fish feed that plays animportant role in the cultivation. Application of probiotics in aquaculture fish feedhas not been done yet in the Fisheries sector. The research was conducted inOctober 2008, Grouper is used as the intestines and stomach samples were takenas a source of probiotics, whereas pathogenic bacteria obtained from thecollection of marine microbiology laboratory of Faculty of Fisheries and MarineRiau University. From the isolation of bacterial strains found 11 strains that havethe potential as probiotics, then proceed to the molecular test by using rDNA16 s.Which is obtained two strains of probiotic bacteria Bacillus cereus and the speciesof bacteria Strenotrophomonas maltophilia. The test results found that theantagonist Bacillus cereus isolates to inhibit the growth of pathogenic bacteriaAeromonas sp and two species of Vibrio sp. While the bacteriaStrenotrophomonas maltophilia showed no antagonism against pathogens.

Mortalitas Benih Ikan Koi (Cyprinus Carpio) Pada Ketinggian Dasar Media Gabus Ampas Tebu Dan Lama Waktu Pengangkutan Yang Berbeda

The aims of this research was determined the effect of the media cork bagasse base height and a long period to transportation on mortality of common carp fry and the average live common carp at the end of rearing. Fish used is common carp fry measuring 8.5 ± 0.5 cm and cork bagasse sized average of 5 ± 0.5 cm. The method used are completely randomized designed factorial pattern 3 x 3 where the first factor was height of basic media cork bagasse (T1 = 5 cm, T2 = 10 cm dan T3 = 15 cm) and the second factor was the length of time trans-portation (W1 = 2 hours, W2 = 4 hours dan W3 = 6 hours) and repeated 3 times. The results showed that the interaction of base height of media cork bagasse and the length of time trans-portation significant effect on mortality of common carp fry. The fastest of the recovered con-scious time showed in length of time the transportation 2 hours was 2.35 minutes, and the longest was 6.56 minutes on the transportation of 6 hours. This showed that the longer the transport time then recovered conscious time of common carp fry getting longer as well. The results of the best interaction was treatment T2W1, where had not fish mortality and avearge of common carp fry that live at the end of rearing for 7 days still maximum. Packing media temperature increased over increasing transport time, but for parameter chemical physics of water during rearing was still within the normal range rearing common carp fry.
