Abstract

Lobster net is Gill Net Monofilament which its operation system is blocking lobster movement. Thus, the lobsters are hooked and winded round onto net. In order to increase the amounts of lobster captured, it is necessary to use bait for collecting lobsters. This research has a purpose to find out is there any interaction between the disposition factor of grabbing tool in 5 and 7 meters depth and the usage of cow hide and goatskin to the amount of lobsters capture (Panulius sp) in Argopeni Kebumen Regency waters. This research uses experimental method. Experimental method is observation under made condition, where that condition is made by the researcher. This method is a methods object which is used to find out is there any cause effect relationship and how big that cause effect relationship. In 5 meters depth using goatskin bait, the amounts of lobster captured are 36. In 5 meters depth using cow hide bait, the amounts are 49. In 7 meters depth, the amounts of lobster captured are 25 by using goatskin bait and 33 by using cow hide bait. The result shows that the difference of grabbing tool disposition gives the effect to the amounts of lobster captured. The difference of bait also gives some effects to that amounts. The result shows that cow hide bait in 5 meters depth gets more lobsters than others.

Abstract

Kendal Regency Seawaters is one of distribution area of potential pelagical fish. If there is no control in the resources utilization, the resources will be threaten. This research aims were to analyze biological and economic aspect of the utilization of the pelagic fish in Tawang fishing port Kendal Regency Seawaters which includes Catch per Unit Effort (CPUE), Maximum Sustainable Yield (MSY), Maximum Economic Yield (MEY), and Open Access Equilibrium (OAE). This research conducted in March-April 2012. Research material was unit of fishing industries was put pelagical fish target in Tawang fishing port. Research method was case study descriptive method. Sampling method was purposive sampling with 30 samples obtained. Data analysis method used time series and bioeconomic method – Gordon-Schaefer Model. This study showed that the average of Catch per Unit Effort (CPUE) pelagical fish potency rate for 2007-2011 in Tawang fishing port Kendal Regency Seawaters is 0, 417 tonnes/trip. The optimum product (Copt) of the Maximum Sustainable Yield (MSY) was 307,168 tonnes per year with optimum effort (Eopt) was 490 trip per year. The optimum product (Copt) of the Maximum Economic Yield (MEY) was 307,008 tonnes per year with optimum effort (Eopt) was 479 trip per year. The optimum product (Copt) of the Open Access Equilibrium (OAE) was 27,342 tonnes per year with optimum effort (Eopt) was 958 trip per year. The pelagical fish resource utilization rate during the last 5 years in Tawang fishing port Kendal Regency has an average rating of 85,57%.

Abstract

Anco is a very simple lift net, generally used only by small fishermans. The shape of the tool is rectangular. The shape is used because after setting and hanging, the other side of the net look like a cup. Anco is used on the edge of the river and the swamp, especially in the estuarine water stream. On that section, there are many small fish schooling because the fish like to swim on the opposing direction of the water stream. Bait is used as stimulant for the fish, so that the fish schools around the anco net. The purpose of this reseatch is to analyze the use of shrimp’s natural bait, worm and cassava against the anco net catch result and to know what bait that has the biggest influence against the anco net catch result. The research method used is descriptive, this research is an experimental research to test modified bait from many kinds of bait (mashed worms, mashed shrimp, mashed cassava) against the catching result in the use of anco net to catch fish. Direct observation method, interview, documentation, and literature is used to collect data. Data is then analyzed using statistic test including testing the normality, testing the homogenity, and one way Anova testing. The results of three treatmens used in the research are shrimp bait, worm, and cassava. The bait which has the most catching result in terms of result, 928 fishes and weighing 3,193 kg, but, the most catching result in the terms of weight is the shrimp bait, weighing 6,466 kg, 840 fishes. The worm bait resulting in 758 fishes, weighing 5,285 kg.

Abstract

The purpose of this research is to determine the effect of the use of construction of the originally hook with the hook kirbed 30o angle, and the influence of different types of bait is natural bait of meat squid (Loligo sp.) with artificial bait, as well as for determining whether or not the effect of interaction between the form of construction the hook and type of the bait on the catch of hand line in the Traditional Fisheries Utilization Zone of Karimunjawa National Park. The research was conducted in May-April 2012 at the Traditional Fisheries Utilization Zone of Karimunjawa National Park. The material used in this study were the hook used to use squid bait, the hook used to use artificial bait, hook angle of 30 ⁰ with experimental fishing methods. Six times the number of repeat tests. Methods of data analysis begins by looking for the hook rate, the data was processed using a statistical test with SPSS 17 software at 95% level tests with tests of normality, homogeneity test, and two way ANOVA test. The results showed that different types of bait is not so affect the catch, the hook construction differences affect the catch Hand line and interaction between the bait the hook with the use of different constructs had no effect on the catch Hand line. Species of fish caught by fishing gear hand line overall during the study based on the percentage of the amount (kg), namely: Badong, pompano slim, large splotch trevally, pompano gargahing, but there were also fish the sergeant fish Badong fish were the most species of fish caught during the research that is equal to 64% of the 54 tail of the total catch.
