Yellowfin tuna (Thunnus albacares) is one of the important catch for the fishing industry in Indonesia. Length-weight relationship study is one of important tools to support fisheries management. However it could not be done to yellowfin tuna landed in Benoa port since they are in the form of gilled-gutted condition. The objectives of this study are to determine the relationship between gilled-gutted weight (GW) and whole weight (WW), to calculate length weight relationship between fork length (FL) and estimated whole weight (WW) and to assess the relative condition factor (Kn) of yellowfin tuna in Eastern Indian Ocean. Data were collected from three landing sites i.e. Malang, East Java; Benoa, Bali and Kupang, East Nusa Tenggara from January 2013 to February 2014. Linear regression analysis applied to test the significance baseline between weight-weight relationships and log transformed length weight relationship. Relative condition factor (Kn) used to identify fish condition among length groups and months. The results showed a significant positive linear relationships between whole weight (WW) and gilled-gutted weight (GW) of T. albacares (p<0.001). There was a significant positive linier relationships between log transformed fork length and log transformed whole weight of T. albacares (p<0.001). Relative condition factor (Kn) showed declining pattern along with length increase and varied among months. The findings from this study provide data for management of yellowfin tuna stock and population.

Albacore (Thunnus alalunga - ALB) catch was the second highest tuna landed at Benoa Fishing Port and they are mostly landed as frozen bycatch. This paper attempts to provide information on ALB catch and effort trends by Benoa based longline vessels collected by the Benoa Port-based Catch Monitoring and Scientific Observer Programs. The ALB catch landed at the Benoa Fishing Port in 2010 was estimated by the Research Institute for Tuna Fisheries (RITF) to be about 983.14 tons, whereas based on the Indonesian Tuna Long Line Association (ATLI), ALB catch landed at Benoa Fishing Port in 2010 amounted of 2,715.42 tons. This discrepancy was due to sampling for frozen catch (including ALB) could not be conducted in some companies and also there was one company that sell their catch direct to the collector. The observed longline sets were concentrated within the area between 10° - 20°S and 105° - 120°E. Since 2008, the observed setting positions have never extended to south of 20°S. The higher catch rates of ALB were in area south of 15°S.

Publisher : Research Center for Fisheries

The reproductive characteristics of mahseer, Tor. tambroides, were studied in Manna River and Batang Tarusan River, which are located on each side of Western Sumatera River. The reproductive period of T. tambroides is largely consistent with that described for the species in other areas, however monthly variations in the extent and timing of peak spawning are recorded. The analysis of the sex ratio indicates an increase in the percentage of females with size, more marked in largest sizes. Seasonal patterns in the occurrences of spawning showed that the spawning season in Manna River lasted was similar with that in Batang Tarusan River, although a second prominent increase of GSI was observed in April and September in Manna River, meanwhile the GSI of Batang Tarusan River fish were below 2 without an apparent variation. L50s of Manna River and Batang Tarusan River mahseer were estimated as 24.5 cm and 20.66 cm, respectively, indicating a high variability in size at first maturity of the mahseer population. Our study provides some important information on the reproductive biology of T. tambroides that will be helpful in similar studies and contributed to fisheries management of this species.

Albacore (Thunnus alalunga) is the third dominant catch of Indonesian tuna longline fishery operating in the eastern Indian Ocean. The percentage production of albacore catch was reaching up 6% of the total catch of tuna groups in Indonesia. Thi study aims to examine a relative abundance indices using standardized catch per unit of effort (CPUE) of longliner based on albacore tuna. This information will give a valuable input and information to support stock assessment particularly in the regional basis. In this study, we use Generalized Linear Model (GLM) with Tweedie distribution to standardize the CPUE and to estimate relative abundance indices based on the Indonesian longline dataset time series. Data were collected from January 2006 to October 2015 (106 trip observer and 8.989 fishing days) by conducting direct onboard observation on tuna longline vessels operating in the Indian Ocean. The result show that year, area,hooks between floats, year*season, year*area and year* hooks between floats significantly influenced the nominal CPUE of albacore. The highest value of Standardized CPUE appeared in 2014 and probably related to the large number of foreign fishing vessels with a high capacity (over 60 GT) targeting frozen tuna including albacore. In 2015, standardized CPUE value was sharply decreased due to the ban of foreign vessels in Indonesia.

Publisher : Research Center for Fisheries

Pelagic fishes such as bullet and frigate tuna in the Indian Ocean were caught in Indian Ocean of Indonesian jurisdiction using various fishing gears including, drifting gillnet and landed in various fishing port in along coastal of west Sumatera (Banda Aceh, Pariaman, Bungus/Padang and Painan) as well as south Java, Bali and Nusatenggara (Muarabaru/Jakarta, Pelabuhanratu, Cilacap, Kedonganan, Benoa). In Cilacap, tuna drifting gillnet fishery is fishing bullet and frigate tuna as by product. The current work describes the catch and size distribution of bullet tuna (Auxis rochei Risso, 1810) and frigate tuna (Auxis thazard Lacepède, 1800) caught by drifting gillnet based at Cilacap Fishing Port. Data and information obtained through catch monitoring, port sampling and landing report of Cilacap Fishing Port 2011 as well as from Capture Fisheries Statistics of Indonesia 2010. The catch estimation of bullet and frigate tuna on drifting gillnet fishery is about 3.220 and 47.346 tons respectively. The catch rate of drifting gillnets on the frigate tuna was 0.364 mt/trip in 2006 decreased to 0.054 mt/trip in 2011 (decreased average 17% per year). The catchrate of drifting gillnets on the bullet tuna was also decreased from 0.178 mt/trip in 2006 to 0.013 mt/ trip in 2011. The FL of bullet and frigate tuna ranged respectively between 16-39cm and 25-46cm. Both species were mostly caught by drifting gillnet in adult size condition.

STRIPED CATFISH (Pangasianodon hypophthalmus) (SAUVAGE, 1878) MOVEMENT AND GROWTH IN GAJAH MUNGKUR RESERVOIR, CENTRAL JAVA Siti Nurul Aida; Agus Djoko Utomo
Indonesian Fisheries Research Journal Vol 21, No 1 (2015): (June 2015)
Publisher : Research Center for Fisheries

Movement is an essential mechanism by which mobile animals acquire the resources necessary for the successful completion of their life-cycles. Striped catfish (Pangasianodon hypophthalmus) contributed about 384 tonnes or approximately 40,04% to the total fish production in Gajah Mungkur reservoir. Diversion of Keduang River, one of Gajah Mungkur important inlets, could affect the the movement of this fish. The objective of this research were to analyze data related to the movement patterns and growth of Pangasianodon hypophthalmus. Field works were conducted from March to December 2011 by tagging experiment of large fish with the PDS-Tags and the T Bar-Tags for the small ones. Fish samples used for the experiment were collected from fisherment catch in Gajah Mungkur reservoir. The tag numbers, the release time, and the fish size were noted before releasing the tagged fish were released. Fishermen who caught the tagged fish were advised to report the fish tag number, time of catching, and fish size. The results showed that the Pangasianodon hypophthalmus could moved as far as 200 m to 15 km in 3- 176 days. In the rainy season most of the catfish moved far into the inlet wiroko and Keduang, and some to the inlet Wuryantoro. Pangasianodon hypophthalmusin Gajah Mungkur Reservoir had growth equation of Lt= 99(1-e 0.762(t-0.15)), with the growth coeficient (K)= 0.762/year, t0=0.15 year, infinity length (L”)= 99 cm. Water diversion of Keduang river, one of Gajah Mungkur inlets, did not fully dried the River during dry season and affected striped catfish movement and growth.
