Abstract

Financial analysis of the artisanal fishery by fish catch marketingdifferences done in Bagan Serdang village, North Sumatra, using survey methodsin data collecting. Fishermen, whose fish-catch market in the government managefish landing place and in the private fish landing place were interviewed. Financialanalysis result shows that yearly income of fishing that market their catch at thegovernment fish landing place earn Rp6,045,000 in average, while at the privateone earn only Rp2,600,000 (t-observe = 3.10 > t-tabel 0,01 = 2.42), thus verysignificance in income difference due to its distinction market pattern. All fishingshow efficient, as BCR > 1 and PPC less than 1.5 years. Eventhough, most of thefishers prefer to market their fish-catch at private landing place, mainly because ofreciprocity, better service and governance in the private landing place, beside‘patron-client’ relationship, in spite of its exploitative in their traditionalrelationship but tight attachment and dependency of fishermen to the individualowner of private landing place.

Abstract

The main problem of Aquaculture is the diseases on the fish. Besides environmentally unfriendly, the using of chemicals as drugs against the diseasesalso producesthe new strain of the disease . The purpose ofthis study were to determine the effectiveness of using the extracts of garlic (Allium sativum), betel leafs (Piper betle), and papaya leafs (Carica papaya) against ectoparasites that infected thetilapia (Oreochromis niloticus) and to determine the immunity of some ectoparasites against each treatment. The methods used was experimental and observation by directly observing the occurrence or incidence of ectoparasites. Water quality parameters measured include temperature and degree of acidity ( pH ). The study was done for 45 days. Analisa Sidik Ragam used to determine the effect of each extract against ectoparasites on tilapia ( Oreochromis niloticus).The studyshowed that the papaya leaf (Carica papaya) has the best effectiveness in reducing the attack of ectoparasites on tilapia (Oreochromis niloticus) compared to garlic (Allium sativum) and betel leaf (Piper betle). The study also showed 12 kinds of ectoparasites that attacked the tilapia (Oreochromis niloticus). The highest incidence values found in the control, and then feed that mixed with garlic, then mixed with betel leafs and the lowest was the feed that mixed with papaya leafs.Keywords: Garlic, Betel Leafs, Papaya Leafs, Tilapia

Abstract

Metals and the other minerals are commonly found in fresh water and sea water, although the amount is very limited. The heavy metals which come into the waters will pollute the sea. One suspected of marine life will be affected due to degradation of water and sediment in coastal environments is shellfish. The aims of this study are to calculate the number of lead concentrations in the water, sediment, and blood cockle (Anadara Granosa) and to analyzed the correlation between lead consentration in water, sediment, and shellfish.This study was conducted in June-August 2013 in Belawan Beach, Bagan Deli Village, District of Medan Belawan, North Sumatra Province. The number of point stations observed were three stations. Parameters measured were water physico-chemical parameters and the concentrations of lead in the water column, sediment, and blood cockle then analyzed by using atomic absorption spectrophotometer (AAS).The results of research on water showed the lead concentration is about 0.64 to 0.91 mg / L. while lead concentration in sediments ranged from 60.78 to 71.56 and lead concentration in mussels is abut 10.48 to 12.03 mg / kg. These results indicate that water, sediment, and shellfish have been contaminated by lead in Belawan Beach.Keywords : Blood cockle, Heavy metals , Lead.

Abstract

Natural food that has a high protein content, easily digestible and small sized could be found in Rotifers genus Brachionus. However, due to the complication of cultivating, it has low rate production. The purpose of this research was to identify appropriate food and to idenfity maximum time of rotifer’s growth The methods used experimental and observation by directly observing the population growth of Brachionus spp. The experiment using a Completely Randomize Design with 4 treatment and 3 repetition. Four treatments include A (Brachionus spp + phytoplankton), B (Brachionus spp + soya bean production waste), C (Brachionus spp + baker”s yeast), dan D (Brachionus spp + vitamin B-Complex).The result showed that there were different population of Brachionus spp to each treatment. The highest population could be found in the soya bean production waste with population value 201x104 ind/ml. The highest population was reached in the eighth day. It revealed that Branchionus spp with high value could be produced in the soya bean production waste and the optimum time was in the eighth day after the spreading.Keywords: Brachionus spp, Population Growth, Soya Bean Production

Abstract

Goldfish (Carassius auratus) is a beautiful freshwater ornamental fish. Price of goldfish depends on several factors, one of them is the body color. Goldfish have stable price in the market whether market demand that continues to increase. Goldfish have characteristics from the type of colors and the beauty of their fins. Color is aesthetics ornamental fish that affect it economical values. Thus, the color should be upgraded and maintained its quality. Such efforts to increase color will be done by adding natural pigment into the feeds. Pigments natural resources can be obtained from Spirulina platensis. The purpose of this research is to know dosage Spirulina platensis that optimal to increase the color of Goldfish. This Research using Complete Random Design (CRD) with three repetition, with the dose treatment by 0 %, 1 %, 3 %, and 5 % for up during 28 days. Additional Spirulina platensis through the feed can increasing colors of the Goldfish. The nutrient that enriched with Spirulina platensis dosage 3% can produce colors brighter than the other dose. Additional Spirulina in the feed has no effect on growth of Goldfish.Keywords: Carassius auratus, Goldfish, Spirulina platensis, Color

Abstract

Goldfish spawning is done naturally, so the success of the nurseries are still low. The success of spawning is influenced by several factors, including the handling of aircraft, particularly in stimulating technological parent spawning, egg incubation and larval treatment. How that can be done to stimulate the provision of parent fish are egg laying substrate. This study aims to determine the type of engaging subsrat eggs that give the best effect on the success of spawning goldfish (Carassius auratus). This research used experimental and observational methods, research design used was a completely randomized design (CRD). Tacks substrate type eggs are used as treatment, water hyacinth (Eicchornia crassipies), rafia rope and sugar falm fiber. Each treatment was repeated three times, so there are 9 units of the experiment. The parameters measured were the number of eggs, hatchability and larval survival goldfish (Carassius auratus). The results showed that the number of fertilized eggs on each substrate goldfish obtained F count>F table then H0 is rejected, it means that there are differences in the number of eggs on the substrate for all three treatments were used. Degree of hatching eggs goldfish sugar falm fiberbest is 63.70%, 61.20% and hyacinth rafia rope 45.79%. Water quality in this study have average values: pH 7 and temperature of 28 0C.Keywords: Carassius auratus, substrates, hatchability and survival

Goldfish as ornamental fish have interesting colour and excellence in body shapes especially the beauty of their fins. The bright and brilliant colors of Goldfish is an attraction that affect it economical values. Thus, the color should be upgraded and maintained its quality. Such efforts to increase color will be done by pigments manipulation techniques with adding suplement into the feeds. The suplement pigments can be obtained from Astaxanthin. The purpose of this research is to know dosage Astaxanthin that optimal to increase the color of Goldfish.this research using Complete Random Design (CRD) with three repetition, with the dose treatment by 0%, 1%, 3%, and 5% for up during 28 days. Additional Astaxanthin through the feed can increasing colors of the Goldfish. The nutrient that enriched with Astaxanthin dosage is 1% can produce brighter colors than the other dose. Additional Astaxanthin in the feed has no effect on growth of GoldfishKeywords : Astaxanthin, Carassius auratus, Color, Goldfish
