Abstract

Catfish is one of the freshwater commodities whose demand continues to increase in Indonesia. Intensive cultivation is done to meet market demand. Intensive cultivation is done by optimizing stocking density. The aim of this research was to know the effect of different density on feed productivity, growth, feed conversion ratio (FCR) and survival of catfish dumbo fry (Clarias gariepinus, Burch) in biofloc and nitrobacter media. This study used a completely randomized design (RAL) with 6 treatments and 3 replications. The test animalsused catfish dumbo (Clarias gariepinus, Burch) with an average weight of 0,6 ± 0,1g and an average length of 4 cm. Catfish dombo seeds are kept in tarpaulin ponds 2 m in diameter with water volume ± 1 m3 for 45 days and feeding 3% of biomass weight. The results showed that the different density of stockingin biofloc and nitrobacter media had increase on productivity, specific growth rate, feed efficiency and no significant effect on the survival of catfish dumbo fry.

Abstract

The local government law regulated the management of 0 – 12 miles waters carried out by the province so that fishermen can operate their fishing gear without differentiating districts. Catch fishing was not limited to one kind of fishing gear and it caused the increasing of fishing capacity. The limited area of fishing with the distance of 2 miles from coast can caused fisheries utilization resources was not balanced. Therefore this study needed to be conducted to assess the status of development of gillnet fishing activities in Dumai waters. Data was collected by conducting interviews in the form of: fishing units, selectivity, sustainability of function and size of fishing vessel with legal documents, and modification of fishing gear. The data results based on 5 fishing technical aspects explained that the fishing utilization of gillnet still could be developed. However, the data of fishing vessel documents have to be well recorded according to the reality so that government could develop the responsible fishing activities.

Abstract

Research related to the influence of facilities on the quality of fish landed and auctioned has been done previously, but the catches under this study are still limited to large pelagic fish with complex fish auction facilities. This study was conducted for small pelagic fish where the handling facilities at this location are still very limited. Therefore, survey research with purpose to analyze the effect of handling facilities (ships, fish auction sites, baskets) on the quality of small pelagic fish. The data taken is daily data with the method of observation at the location on the ship, fish auction place, and baskets. The species that taken were Eleutheronema tetradactylum, Ilisha elongate, Pampus argenteus, and Johnius trachychepalus. Each species consists of 5 individuals. Its tests was done by looking at the organoleptic and pH values. The tests were done to every species of fish. The pH value was obtained by testing the fish meat sample on the meat pH meter, while the organoleptic value was obtained by looking at the physical condition of the fish using a score sheet of fresh fish quality parameters. Then after the results are obtained, an analysis is carried out to determine the magnitude of facility influence on fish quality by simple linear regression analysis. The organoleptic values of four kinds of samples were on average 6.84 - 4.95, while the pH values measured in these fish ranged from 6.3 - 5.94. The effect of fish handling facilities on the organoleptic value is 82% compared to other factors. The fish quality as measured by the organoleptic test showed a fairly good quality, while measured by the pH test showed good results. Handling facilities do not greatly affect the quality of fish and there are other factors that can affect the decline in fish quality other than facilities. The relationship between fish handling facilities and quality can give an overview of the contribution of handling facilities to fish quality.Keywords:Fish auction marketFish qualityHandling facilities

Abstract

Setiap operasi penangkapan ikan tidak terlepas dari proses manajemen yang dilakukan secara bertahap mulai dari perencanaan (planning), pengorganisasian (organizing), pelaksanaan (actuating) dan pengendalian (controlling) agar ketercapaian penangkapan ikan dapat dipenuhi. Purse seine merupakan alat tangkap yang menghasilkan produksi perikanan yang paling tinggi di PPS Nizam Zachman Jakarta. Kajian mengenai proses manajemen operasi penangkapan masih terbatas sehingga perlu dilakukan kajian mengenai manajemen operasional penangkapan pada KM. Mekar Kencana 03 di PPS Nizam Zachman Jakarta. Pengumpulan data dilakukan dengan observasi kegiatan penangkapan ikan di KM. Mekar Kencana 03 dan wawancara. Analisis data yang digunakan adalah analisis deskriptif kualitatif. Persiapan keberangkatan dilakukan 30 menit sebelum keberangkatan. Jumlah anak buah kapal saat melakukan penangkapan di laut minimal sebanyak 32 orang termasuk nakhoda. Perbekalan disiapkan sesuai dengan jumlah awak kapal. Kondisi kapal harus dipantau seperti mesin induk dan mesin gardan. Dokumen perizinan kapal harus disiapkan, pengecekan alat tangkap dan pengecekan alat navigasi kapal juga dilakukan. Pengawasan operasi penangkapan dilakukan langsung oleh pemilik kapal yang berperan sebagai nakhoda kapal. Kata kunci: manajemen, operasional, purse seine, PPS Nizam Zachman

Abstract

One of the problems faced in the development of the marine and fisheries sector nationally is the low quality of the fish capture due to the limited capacity and quantity of available port infrastructure resulting in the decrease in competitiveness. The data in this study were related to fish capture from fishing boats to wholesalers. The data obtained was observation of the location of the vessel, the fish auction place, and the marketer. The types of fish taken were Kurisi (Nemipterus pneumatophores), Biji Nangka (Upeneus mullocensin), Kapas-Kapas (Gerres erythronium), Bawal Putih (Pampus argenteus), Kembung (Rastrelliger spp). Fish examining was done by looking at the organoleptic and pH values. The pH value was obtained by testing the pH meter, while the organoleptic value was obtained by observing the physical condition using a score sheet. To determine the magnitude of the influence of facilities on fish quality, and the correlation between organoleptic values and pH, an analysis using simple linear regression was conducted. The average organoleptic value of fish while on the boat, when distributed, and when in the marketplace were 8,248; 7,024; and 6.6 respectively. Meanwhile, the average pH value was 7.05; 5.51; and 5.15. The quality of fish caught at Class A Fishing Port of Belawan is still of good quality. The pH test showed decline in pH value ever since the fish was brought to the port until they were marketed. The influence of facilities on the fish organoleptic and pH value are 98.3% and 96%. Thus, facilities significantly affect fish quality at Belawan Fishing Port. Between pH and organoleptic values showed a positive correlation, hence when the pH value decreased, the organoleptic value also dropped.Keywords:Belawan Fishing PortEast WatersFacilities InfluenceFish Quality
