Opis:
Prediction about fishing season is needed for fishing operation, so it can help fisherman to catch a big number of fish with effective and efficient. This study was started on May – June 2018. This study aimed to analize fishing season pattern of big eye tuna in Indian Ocean. Historical data about fish production and fishing effort of long line vessel for 5 years (2013-2017) collected from Indonesia Tuna Longline Asociation (ATLI) in Benoa Port, was used to calculate monthly CPUEs which were then analyzed using average percentage methods to obtain fishing season index for each month and sea surface temperature (SST) data collected from satellite. The result shows that big eye tuna can be caught along the year, but there was a pattern that fishing season occurs from June – September, December, and April with the peak season in east season. Optimum distribution of sea surface temperature base on big eye tuna’s fishing ground ranged from 27-27.5 °C.

Opis:
This research aims to determine the ratio percentage of white meat surimi and red meat surimi of tuna in the making of fish burger in the most preferred by the panelists. The method used for this research in experimental with 5 treatments, which are the usage of 100% content of white meat surimi and the combination of white meat surimi and red meat surimi with the percentage of 90%, 10%, 80%, 20%, 70%, 30%, 60%, 40% based on the weight of white and red surimi meat, involving up to 20 semi-trained panelists as rehearsal. The observed parameters are the yield calculation percentage of white and red tuna fillet, surimi’s yield and fish burger’s yield, hedonic test (preference level) based on organoleptic characteristic covering the appearance, aroma, texture and taste of tuna fish burger along with chemical test (protein value, fat value and water level) to fish burger. According to the result to the fish burger’s level of preference it can be summarized that the comparison of tuna’s white meat surimi and red meat surimi for every treatments are liked by the panelists, however the treatment of 80% white meat surimi and 20% red meat surimi tuna is the most preferred treatment by panelists with the median characteristic value of appearance, aroma, and texture of 7 (liked) and taste 9 (very liked). The amount of the protein value is 13.99%, fat value is 2.36%, and water value is 31.28%

Opis:
The Bali Strait has very high pelagic fish resources, ranging from small pelagic fish to large pelagics, one of which is a type of tuna. Skipjack tuna (Euthynnus sp.) is one of the dominant and high economic value fish resources. The composition of fish catch landed in National Fisheries Port (PPN) Pengambengan in 2014 is dominated by small pelagic fish. The composition of the largest fish catches consists of lemuru, skipjack, mackerel and scad. This study aims to look at the production of skipjack tuna and season distribution for 5 years. This information can be used as an effort to manage fisheries in PPN Pengambengan continuously. This research was carried out in the waters of the Bali Strait with fishing base PPN Pengambengan. The catch of skipjack tuna in Bali is fluctuated every month during 2013 until 2017. The average catch is high in 2014, and the lowest catch was in 2016. This was allegedly due to the catches of previous years namely in 2014 – 2015 skipjack tuna fish resources were overexploited. The catch of skipjack tuna based on the season has the highest value in September - November (transition II (intern-monsoon)) and the lowest is in December-February (northwest season).

Opis:
The research was conducted at the Tuna Fisheries Research Station, Denpasar, Bali, in July 2018 (3 weeks duration). There were several types of high-value fish incorporated into this research: tuna, skipjack, shrimp, cob, mackerel, snapper, squid, reef fish (grouper, baronang, lobster / barong shrimp) and ornamental fish. Seaweed processing was also assessed. Benoa Fishing Port is one of the tuna landing base bases in Indonesia. It is the main port in Bali Province and ranks beside Muara Baru (Jakarta), Pelabuhan Ratu (West Java) and Cilacap (Central Java). This research aim to identified length-weight relationship, and proportion of proper catch size of bigeye tuna. Herein, bigeye tuna (Thunnus obesus) was identified visually and then assessed. The first identifier is the large size of the eye. The growth pattern of big eye tuna (Thunnus obesus) landed in Benoa Fishing Portis is isometric, where the length increase is equal to weight gain (isometric positive). The length distribution of big eye tuna was in range of 81-170 cm FL (334 fishes are obtained), and the distribution of weights varied in size from 11-95 kg, with the most common catch size being in the range of 16-20 kg (95 fishes). Of note, 60% of the fish had not reached the proper catch size.
