Abstract

The accumulation of waste in aquaculture can cause inorganic toxins  named ammonia (NH3) and nitrite (NO2) in water. Biofloc technology is one of the new alternative to solve the problem of ammonia (NH3) and nitrite (NO2) in aquaculture techniques adapted from sewage treatment. This study aims to determine the effect of stocking density of catfish (Clarias sp.) using biofloc system against ammonia and nitrite. This study used an experimental method to completely randomized design (CRD). Statistical analysis using Analysis of Variant (ANOVA) to determine the effect of treatment.The results of the study showed that the effect of stocking density of catfish (Clarias sp.) were significantly different (P <0.05) against ammonia (NH3). The lowest average production levels of ammonia (NH3) was the PO treatment (stocking density 15 fishes/15 L) of 0.1689 ± 0.0052, and the highest was treatment P3 (stocking density 30 fishes /15 L) of 0.1819 ± 0.0016. Effect of stocking density of African catfish (Clarias sp.) was not significantly different (P> 0.05) to nitrite (NO2). The lowest average content of nitrite production (NO 2) was the PO treatment (stocking density 15 fishes/15 L) of 0.0358 ± 0.0028 and the highest was P3 treatment (stocking density 30 fishes/15 L) of 0.0388 ± 0.0042. During the culture. temperature was  26,4-29,70C, dissolved oxygen was 5.2 to 8.3 mg / L and pH between 7.01 to 8.66.   Keywords : Biofloc, ammonia, nitrite

Abstract

Catfish is one of the fish that has a high economical value. Catfish is accepted by society easily because of its advantages. These advantages include fast growing, good adaptive behavior, good taste, high nutrient, and cheap price. One of the factors that determine the success of aquaculture is the availability of adequate food, both quantity and quality. There are several alternative feed ingredients that can be used in the preparation of feed. One of these feed ingredients is azolla flour made from Azolla sp. plant. Azolla sp. plant contains large amount of protein up to 28,12% of its dried weight. Selection of the base material feed using Azolla sp. based on the research results Handajani (2000) which declare that the protein content Azolla sp. which is quite high, namely 28.12% dry weight. The addition of Azolla sp. in catfish feed formulation is expected to improve retention of energy and lower feed conversion ratio. The purpose of this study was to determine the addition of Azolla sp. in feed formulations affect the retention of energy and feed conversion ratio catfish. This research was conducted in July-August in the Faculty of Fisheries and Marine University Airlangga. Research method used in the study was an experimental method with complete random planning. It included five treatments and four repetitions. Treatments that were used included azolla flour inclusion 0%, 5%, 10%, 15% and 20% at the formulated feed. Data analysis that was used included statistic and descriptive. The result of the research shows that energy retention among treatments does not have significant difference. On the other hand, the feed conversion ratio also does not have significant difference. It can be concluded that Azolla sp. inclusion in the catfish feed formulation affects nothing to energy retention and feed conversion ratio.     Keyword : Azolla sp., Clarias sp., Energy Retentiom, Feed Convertion Ratio

Abstract

Catfish (Clarias sp.) is a type of consumption fish have promising prospects because it has a high enough degree of market uptake. The high market demand which motivated farmers to develop farming aquaponics technologies. Aquaponics, in principle, in addition to conserve land and water use also increases business efficiency through the utilization of nutrients from food remains and fish for plant metabolism. Fish farming with high stocking density causes a decrease in water quality due to the accumulation of organic matter buildup of organic materials causing toxins in the water because there is ammonia (NH3) and nitrite (N02) on the water. The threshold for catfish ammonia content is <0.8 mg /L. Alternative to overcome the problem of water quality in aquaculture is the addition of probiotic. Probiotic contain several types of microorganisms that can help the process of decomposition of ammonia as a bioremediation agent for water quality control. The purpose of this research is to determine the effect of different probiotics in the aquaponics system to water quality. The method that used in this research is experimental with completely randomized design (four  treat and five repeated) are P0 (control), P1 (probiotic A), P2 (probiotic B) and P3 (probiotic C). Analysis of data processed using Analysis of Variance. If there are significant differences then continued Duncan's Multiple Range Test. The results showed that the giving of probiotics in the aquaponic system is significantly different (p<0.05).The final conclusion is that the addition of probiotic in the aquaponic system affect the water quality. Based on the results of statistical analysis showed that the levels of ammonia, nitrite and nitrate was lowest for the treatment of P2 is 0.0204 mg /L, 0.012 mg /L and 2.731 mg /L. Ammonia, nitrite and nitrate is highest at P0 treatment (control) is 0.273 mg /L, 0.019 mg /L, 4.218 mg /L.   Keywords : Aquaponic, Catfish, Probiotic, Ammonia, Nitrite, Nitrate, Clarias sp.

Abstract

Catfish (Clarias sp.) is a freshwater fish that is widely cultivated because it is a leading commodity. Increased production of catfish resulted in extra area of cultivated land and water use. The technology suitable to be applied is aquaponic system. In addition to saving land and water use, Aquaponic is also improving business efficiency through the utilization of nutrients from food remains and fish metabolism. Water quality is an important factor for the success of cultivation. Maintenance catfish with the addition of probiotics in aquaponic system can be a solution for maintaining water quality, because it contains bacteria that can increase nitrite to nitrate changes that can be utilized for growth of plants and do not poison the fish. The purpose of this study was to determine the effect of different probiotics in the aquaponic system towards growth rate and survival rate of catfish. The method that used in this research is experimental with completely randomized design (four  treat and five repeated) are P0 (control), P1 (probiotic A), P2 (probiotic B) and P3 (probiotic C). Analysis of data processed using Analysis of Variance. If there are significant differences then continued Duncan's Multiple Range Test. The results showed that the giving of probiotics in the aquaponic system is significantly different (p <0.05). The final conclusion is that the addition of probiotics in  aquaponic system affect the growth rate and survival rate of catfish. The highest specific growth rate (0.025%/ day) and the highest survival rate (77.8%) contained in the P2 treatment. The lowest specific growth rate (0.019% /day) and the lowest survival rate (64.4%) contained in P0 treatment (control).   Keywords : Aquaponic, Catfish, Probiotic, Growth Rate, Survival Rate, Clarias sp.
