The coastal waters of Wonorejo is part of the East Coast Surabaya which receive the brunt of watersheds (DAS) from other rivers. The main source of heavy metal wastes in the River on the downstream Wonorejo pass several industries suspected of disposing of hazardous waste. One of the main heavy metal which is a toxic element and effect on aquatic ecological systems are cadmium (Cd).Mud crab is one potential biota found in the mangrove area of Wonorejo River Surabaya can accumulate heavy metals. This research was carried out in April 2018 with sampling at three stations with time each week for three times.Analysis of heavy metals cadmium (Cd) in mud crabs (Scylla sp.), water and sediments carried out in the laboratory of nutrition of the Faculty of public health University Airlangga. Research method using observation which is channeled in the waters and farmed in Wonorejo Surabaya. Mud crab meat samples, water and sediments tested using Atomic Absoption Spectrophotometry (AAS). The results of the test concentration of heavy metals cadmium (Cd) in mud crab meat on the river Wonorejo i.e. 0.032 mg.kg-1 where the value of these levels are still below the threshold of quality raw heavy metal Cd on crustaceans i.e. 1 mg.kg-1 (SNI 7387:2009). The Cd content in water of Wonorejo river in between 0.014-0.02 ppm and on sediments between 0.234-0.416 mg/kg. Correlation of cadmium content in water with crab meat in the correlation coefficient shows of Wonorejo -0.22 (a weak correlation, a negative direction). Then, the correlation of the content of cadmium in sediments with crab meat in the correlation coefficient shows of Wonorejo 0.285 (of correlation is weak, the positive direction).

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).

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.

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.

Surabaya is one of the East Java region with relatively high levels of fish consumption. In a food fish production activity in Surabaya, one of the species of fish which allows for developed through cultivation is catfish. Since catfish has the advantage than other fish because it has good durability and can be cultivated in high density. African catfish cultivation activity will be increase if it is developed in coastal region of Surabaya because there is many potential of fish catches waste as feed which are underutilized by coastal communities. Only this time the land and water resources of coastal area in Surabaya are generally limited, so it is necessary to know a model of African catfish fish farming with the use of limited land and water resources. For overcoming these problems, it is needed system of fish farming technology appropriate to be applied to the activities of African catfish farming in Surabaya and the technology is the dumbo catfish cultivation with intensive system akuaponic. AbstrakSurabaya adalah salah satu wilayah Jawa Timur dengan tingkat konsumsi ikan cukup tinggi. Dalam kegiatan usaha produksi ikan konsumsi di kota Surabaya, salah satu spesies ikan yang memungkinkan untuk dikembangkan melalui kegiatan budidaya adalah ikan lele. Sebab ikan lele memiliki keunggulan dari ikan-ikan lain karena termasuk ikan yang memiliki daya tahan kuat dan dapat dipelihara dengan padat tebar tinggi. Kegiatan budidaya lele dumbo akan semakin marak apabila dikembangkan di wilayah pesisir Kota Surabaya mengingat banyaknya potensi bahan pakan murah berupa limbah ikan tanggkapan yang kurang dimanfaatkan oleh masyarakat pesisir. Hanya saja saat ini lahan dan sumber air masyarakat pesisir kota Surabaya umumnya terbatas, sehingga perlu diperkenalkan suatu model budidaya ikan lele dumbo dengan pemanfaatan lahan dan sumber air yang terbatas. Mengatasi masalah tersebut, diperlukan sistem teknologi budidaya ikan yang tepat untuk diterapkan pada kegiatan usaha budidaya ikan lele dumbo di kota Surabaya dan teknologi tersebut adalah budidaya ikan lele dumbo dengan intensif sistem akuaponik.
