Abstract

Transportation of live tilapia impact evaluated from Pasar Besar, Malang city. Pasar Besar tilapias were supplied from Sidoarjo and Malang Regency. Transportation impact can be identified from tilapia meat quality. pH levels, TVC (Total Viable Count) and TVB (Total Base Nitrogen) determined as tilapia meat quality. pH levels, TVC and TVB showed stress comes from transportation impacted tilapias meat quality.

Abstract

Channa striata is the one of the local comodity in West Kalimantan Province which has important economic value. The demand for Channa striata comes mostly from urban communities, while urban areas only have narrow land / yard. One of the techniques of fish cultivation in narrow land is the aquaponics system. Thus, Channa striata cultivation with the aquaponics system can increase the productivity of cork fish in urban areas. The purpose of this study was to obtain the optimal amount of stocking density in Channa striata culture with an aquaponics system with indicators of success namely survival and growth rate. This study lasted for 75 days, taking place at the Pontianak City Fish Agribusiness Farm. The study design used a Completely Randomized Design (CRD) with 4 treatments and 3 repetitions, The stocking solid treatment used in this study is A: 40, B: 60, C: 70, and D: 50 tails / m2. The results showed that treatment A had a significant effect on the absolute growth rate of 12.85 gr followed by perlkuan D: 12.46 gr, B: 8.87 gr, C: 7.9 gr, while the best specific growth rate was needed at time A: 3.50%, D: 3.44%, B: 3.05%, C: 2.91%. The observation of life survival also has the same trend, namely the best treatment in treatment A: 95%, D: 90%, B: 70%, C: 49%. From the results of these studies it can be concluded that the higher the stocking density in aquaponics fish farming systems will have an impact on the growth rate and the survival rate of Channa striata with the best treatment, namely with stocking density of 40 fish / m2.

Abstract

The river is a natural and/or artificial water channel or container in the form of a water drainage network with water in it, from the upstream to the estuary, with the right and left borders bounded by the boundary line. The problem that often occurs in the river area is pollution. This research is focused along the Acai River flow located in Abepura District, Jayapura City, Papua Province. Problems that often occur along the Acai River flow in Jayapura City are the accumulation of garbage in the river body and changes in the physical condition of the river, both color and odor. Therefore, the purpose of this study is to determine the status of water quality from the Acai River so that it can be used as a reference in determining the sustainable management of the Acai River. The method used to determine the status of water quality was the pollution index method. Measurements were carried out in the upstream, middle and downstream parts of the Acai River. The results showed that the Acai River Pollution Index (PI) in the upstream reaches ranged from 1.75 to 5.35. The middle part of the Acai River has a Pollution Index (PI) of 1.84 - 5.41, and the downstream part has a PI of 1.78 - 5.39. Based on these data it was known that the overall Pollution Index (PI) in the Acai River ranges between 1.75 - 5.41. Pollution that occurs in the Acai River was caused by pollution of organic material obtained from domestic waste. This was shown from the results of measurements of water quality where BOD levels are 2.58 - 4.54 mg / L and COD is 190 - 193 mg / L. The Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels of the Acai River have exceeded water quality standards. Based on the measurement results of the Pollution Index (PI) it can be concluded that the Acai River has experienced pollution from the low to moderate categories, for water classes ranging from Class I to Class IV. For this reason, it was suggested that an integrated domestic waste treatment plant be made which can accommodate domestic waste as a result of community activities and process it first before finally being discharged into the river water body.

Abstract

Koi fish (Cyprinus rubrofuscus) is included in freshwater ornamental fish commodity which has high economic value. As high of the market demand, it must be balanced with the increase of Koi fish production, especially in the hatchery sector. One effort that can be done is by preserving sperm with the addition of a solution of palm juice and ringer lactate. The purpose of this study was to determine the effect of the difference and the best value of the concentration of palm juice in ringer lactate during the storage period on the fertility power of Koi Fish sperm. The research method that used is the experimental method with the main parameters of motility, viability, fertilization, hatchability, survival rate and supporting parameters of macroscopic quality of fresh sperm and water quality. The results showed that the addition of palm juice and ringer lactate gave a very real effect on the level of motility with the best value on treatment B that is equal to 50.33%, the level of viability with the best value at treatment B that is equal to 64.67%, fertilization rate with the best value at treatment B that is equal to 84,91%, hatchability level with the best value at treatment B that is equal to 69,80%, but no significant effect to survival rate of the juvenile. The function of palm juice and ringer lactate is providing energy and keep the balance of the fluid in sperm that is useful to keep sperm still alive and still moving.

Abstract

The Grouper (Cromileptes altivelis) is a species of fish that has a significant economic value which selling price is quite high. High fish prices encourage fisherman to exploit continiously. This will lead to an over fishing. Grouper farming has a bright opportunity in the future but it is still facing difficulties in rearing. So some of the parameters should be focused. One of them is the stocking density which closely related to the area of rearing. The purpose of this study was to determine the growth rate of fish grouper wich different stocking density tratments in floating net cages. The method used in tratments and 3 replications. There were 9 cages used with size used 1x1x1,5 m. and mesh size of 0,5 inches as rearing place. Initial weight of grouper fish were observed at the time of stocking density 5 grams. Condition of aquatic environments is suitable for grouper growth  except for the low flow velocity. The rearing of grouper fish with different stocking density treatments showed a significant different. The highest growth was represented by treatment A wich was 25,40 grams, followed by treatment B with 23,26 grams and treatment C was 22,10 grams.

Abstract

The high demand of shark products, particularly fins, have influenced the increase in the exploitation and trade of sharks, included small scale fisheries. The condition can increase the vulnerability of sharks because of their biological cycle and as a top predator and economically important fish. This paper aims to identify the conditions of exploitation and management of sharks in Sumenep Regency. The method used in this research is the field observation, in-depth interview and review of policies. Based on the existing results indicate that over exploitation has occurred in Sumenep, where fishermen catch almost any size of sharks, both great until the baby sharks ('baby hiu’) in large numbers. Several species of sharks that many caught are the species Carcharhinus melanopterus, C. obscurus, Sphyrna lewini and Chiloscyllium punctatum. Shark trade activities occur in Tempat Pelelangan Ikan (TPI) of Pasongsongan, the fishing port of Ambunten, Dasuk, Dungkek, and Tanjung–Saronggi. Currently, the regulations governing the management and protection of sharks in Indonesia is still limited to only a few species of sharks, including whale sharks (Rhincodon typus), shark saws (Pristis Microdon, P. clavata, P. zijsron, and Anoxypritis cuspidata), and manta rays (Manta birostris and M. Alfredi), although other species has status Near Threatened until Endengered based International Union for Conservation of Nature (IUCN) and Appendix II based on the Convention on International Trade in Endangered species (CITES). Not to socialized existing regulations to the fishermen, the absence of regional policy in particular, and the high price is one reason still rampant shark fishing on a large scale. To that end, public awareness activities to fishermen and communities and appropriate regulation is needed in sustainable shark management efforts.
