Availability of water in swamp areas is abandon almost throughout the year, therefore these areas are potential for aquaculture development. However, the characteristics of swamp water is mainly acid water, therefore, it becomes mayor problems in swamp fish culture development. Liming of ponds is intended to increase pH value of soil and water of fish ponds. A. granosa shells is one of domestic waste containing of 61.16% CaO and 21.65% MgO, therefore it can be used as an alternative material for liming of fish ponds. The aims of this research was to evaluate the potency of lime derived from A. granosa shells to raise soil’s and water’s pH, and to evaluate its effect to survival and growth of Pangasius sp. The research was conducted and arranged based upon completely randomized design with five treatments and three replications. The treatments used consisted of different dosages of lime, namely : P1) 1 ton/ha; P2) 2 ton/ha; P3) 3 ton/ha; P4) 4 ton/ha and P5) 5 ton/ha of lime equivalent to CaO. The results showed that both the soil and water reach a neutral pH at a dosage of 2 ton/ha (P2), 3 ton/ha (P3), 4 ton/ha and 5 ton/ha. The dosage of 5 ton/ha (P5) was the best treatments among all treatments, with a highest survival rate (100%), absolute growth of fish lenght (9.35 cm) and weight (40.69 g), as well as feed efficiency (110.97%).

Organic liquid fertilizer is the source of nutrients. This fertilizer can be used to improve the water quality. It is enviromentally friendly and relatively cheap. Application of the fertilizer has been done on aquaculture. At the tidal lowland areas, application of this fertilizer is mostly as soil improvement agent. It is limited to be used as water quality improvement agent. Tidal lowland has an acid soil with a low fertility level characters. The objectives of the study are to know the effect of liquid organic fertilizer to the water quality (temperature, pH, dissolved oxigen, ammonia) and to the amount of plankton in the ponds. This research was done at the reclaimed tidal lowland in Banyuasin District of South Sumatera, Indonesia. The organic liquid fertilizer was made by fermentation of both animals manures and vegetable waste with the percentage of N : P2O5 : K2O were 0.120 : 0.023 : 0.750. Water quality data was taken three times in every three days (plankton) from the ponds that was added by liquid fertilizer with dose of 4.35 L /pond (P1) and 8.7 L/pond (P2). All the water quality data were analyzed qualitatively. The results show that on treated ponds pH dropped slightly since the beginning with pH 6.0 and remain 6.4 - 6.8 in the last day. The value of Ammonia ranges 0.06-0.15 mg.L-1 and Dissolve oxigen range 1.9-2.5 mg.L-1‑. Phytoplankton and zooplankton amount increased and reached the peak on day 12 (12033 ind.L-1 and 364 ind.L-1 respectively), and finally turned down slowly. Therefore, liquid fertilizer addition should be given to the ponds more than once during fish rearing period. It is in order to increase the amount of plankton and to manage the water quality in the reclaimed tidal lowlands ponds

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.

Naturally, during dry season, pyrite tent to be oxidized due to soil water content and groundwater level decrease. This paper aims to evaluate the influence of soil water condition and ameliorants on pyritic soil pH dynamics. Pyritic soil was taken from a depth of 70-90 cm below soil surface in the acid sulphate land located at Mulyasari Village, Tanjung Lago District, Banyuasin Regency, South Sumatra. The research was carried out in greenhouse with 2 treatment factors, namely: Water condition (K1 = water condition maintained at 5 cm above soil surface during incubation period and K2 = water condition at 5 cm above soil surface and allowed to decrease during incubation period) and ameliorant (T = Without Ameliorant, B = Organic Matter, D = Dolomite, P = Phosphate Fertilizer and S = Silicate Coal Ash). The results showed that pyritic soil pH tended to be stable during incubation period for K1 treatment, and pH of soil treated with dolomite > Silicate Coal Ash > Organic Matter > P Fertilizer > Without Ameliorant. Meanwhile for K2 treatment, soil pH tended to decrease with the highest rates are 21.58x10-2, 19.33x10-2, 4.38x10-2, 7.50x10-2, and 12.07x10-2 pH unit per day, respectively for without ameliorant, organic matter, dolomite, phosphate fertilizer and silicate coal ash. The highest rate of decrease in pH of pyritic soil occurred in the range of decreasing water content from 66.31 to 41.73% for without ameliorant, organic matter and phosphate fertilizer, from 41.73 to 13.93% for silicate coal ash, and from 13 .93 to 8.22 % for dolomite. These findings can be applied for managing pyritic soil by maintaining soil water content from falling under water content critical limit range and under uncontrolled dry conditions it is recommended to use lime to minimize pyrite oxidation.

Catfish (Clarias gariepinus) that are reared with probiotics as biofloc-forming agent is thought to increase the fish production. Applying swamp probiotics to the water media has never been studied to ensure the flocks' availability in the rearing media. This study aimed to determine the appropriate frequency of probiotics application collected from swamps for biofloc formation to improve the catfish production. This study used a completely randomized design with two treatments and three replications. The treatments were composed of different application frequency of swamp probiotics: (P1) once in 42 days of rearing and (P2) twice in 42 days of rearing. Data on flock volume, total bacterial colonies, absolute growth rate, feed efficiency, survival rate, and water quality were analyzed by T-test with a 95% confidence level. Meanwhile, the flock composition data were analyzed descriptively. The results showed that P2 obtained the best treatment with a floc volume of 68.33 10.41 mL/L, absolute length growth of 8.18 1.03 cm, absolute weight growth of 19.30 3.12 g, feed efficiency of 135.24 7.98%, survival rate of 89.33 6.21%, biomass production of 24639.50 1344.51 g, temperature of 28.85-29.59C, pH of 7.27-7.42, dissolved oxygen (DO) of 3.91-5.72 mg/L, ammonia of 0.45-1.15 mg/L, and total dissolved solids (TDS) of 717.33-885.50 mg/L. Therefore, swamp probiotics should be applied to catfish culture media twice for 42 days of rearing or once every 21 days.Keywords:BioflocCatfishProbiotics from swamp
