Abstract

This research was carried out with a rocky (Cliffs: 36°53'3.13"N; 30°41'49.78"E) stony and gravelly bottom (Konyaaltı beach: 36°53'0.07"N; 30°4043.36"E) in two different regions of Gulf of Antalya. This study was intended to determine the fish species that use the long-spined sea urchin (Diadema setosum Leske, 1778) as a shelter. In the study, the fish that use the sea urchin in the rocky area as a sheltered area Chromis Chromis, Cheilodipterus novemstriatus, Thalassoma pavo, Coris julis, Tripterygion melon rum, Gobius bucchichi. Of these species, only C. novemstriatus is exotic. Others are native species of the Mediterranean. C. Chromis juveniles were the densest among the sea urchin spines in the rocky region, while C. novemstriatus formed the second crowded species. In the study carried out in the second area, which has a stony and gravelly bottom structure, fish species that use sea urchins as shelter are C. novemstriatus, Siganus rivulatus, Apogonichthyoides pharaonic, Pteragogus pelycus, Parupeneus forsskali, Pterois miles, Sargocentron rubrum, Epinephelus aeneus and C. julis. Of these species, only E. aeneus and C. julis were determined to be native species of the Mediterranean. All other species are Red Sea species, with Rabbitfish (S. rivulatus) fry as the densest species, C. novemstriatus in the second place and A. pharaonis in the third place are. It was determined that adult and juvenile individuals of C. novemstriatus, A. pharaonic and P. pelycus used sea urchins as shelter, and only juveniles of other species. In addition, among the sea urchin spines, most of the C. novemstriatus, and A. pharaonis individuals were found to carry eggs in their mouths. According to the findings obtained in this study, it can be said that the long-spined sea urchin, which increases its population rapidly in the Mediterranean, also contributes to the increase in their population in the Mediterranean by creating a shelter for some fish species of Red Sea origin that cannot be economically evaluated and invaded.

Abstract

Knowledge of fish behavior and its relationship to environmental factors is needed to develop fishing gear operating methods to be more effective. Fish targetting is no longer seen from the catch (amount) result. The target fish is no longer seen from the quantity of catch but rather the quality of the catch). This is done to maintain the sustainable use of fish resources. Data collection was conducted from November 24 to December 3, 2015, at Pelabuhanratu. This study aimed to determine the relationship between fish behavior and environmental factors in the upper thermocline (Zona-Up), thermocline and lower thermocline layer (Zona-Un). Observations were carried out at intervals of 6 hours: morning (6:00 - 08:00 WIB), daytime (12:00 - 14:00 WIB), afternoon (18:00 - 20:00 WIB) and evening (00:00 - 02:00 WIB) using echosounder in FADs. Acoustic recording tracks form stars around the FADs. Measurement of environmental factors was achieved using the CTD Sea bird SBE 19 plus V2. The measured environmental parameters were temperature (ºC), salinity (PSU), dissolved oxygen (mg / l), chlorophyll (mg / m3), conductivity (S / m) and seawater density (kg / m3). The results showed that the factors that had a significant relationship between fish abundance and environmental factors in the zone-up were temperature and salinity. In contrast, the key factor in the thermocline and un-zone layers was temperature.

Abstract

Kawakawa (Euthynnus affinis) is one of the important catches of small-scale fisheries in Indonesia. This species is included in the neritic tuna group that mostly utilized by using purse seine and gillnet. This research aims to investigate the Nominal CPUE, Length distribution, and condition factor of kawakawa. Data collection was conducted for 11 months from February to December 2019 in Aceh, Sibolga, and Bengkulu (FMA 572). A total of 1,622 specimens was collected, measured (cm FL) and weighted (kg). CPUE analysis shows the fluctuations in each month, with the highest CPUE value in August and the lowest in May. The measurements showed that the length ranged from 20 – 55 cm FL and weight ranged from 0,13 – 3,06 kg. Analysis of length-weight relationships was W=0,00001FL3,1079 with a determination coefficient (R2) 0.967. The growth pattern of positive allometric. The highest relative condition factor (Kn) occurred at the upper limit of length class 21 cm FL with a value of 1.25 and the lowest at 57 cm FL with 1.06. The monthly relative condition factor tends to stabilise, with the highest value in December at 1.265 and the lowest in April at 1.081 and tended to fluctuated for the small-sized group. At the same time, adult fish tends to decrease along with the length increase.

Abstract

To support improving fisheries management on tuna fisheries in Indonesia FMA (I-FMA) 713-717, an Indonesia - Australia research collaboration conducted a study during November 2013 – December 2015 at two key tuna fishing bases including Kendari (Southeast Sulawesi) and Sorong (West Papua). This study involved an enumeration program with skipper interviews, direct observations and biological sampling. The study showed that all fish aggregating devices (FADs) in Indonesian waters are anchored fish aggregating devices (aFADs). Three main fisheries associated with aFADs include purse-seine (PS), pole and line (PL) and hand-line (HL). The PL fishery based in Sorong had the highest FAD-success rate-FSR (84.9 %) compared to other fisheries including PL and HL based in Kendari. The average catch rates of PL and PS boats based in Sorong 2013-2015 were 10,352 and 33,854 kg/trip/boat respectively. The average catch rates of PL and HL boats based in Kendari were 2,819 and 1,135 kg/trip/boat respectively. Apart from the catch of HL based in Kendari, the largest proportion of the catch was juvenile yellowfin tuna (j-YFT) and juvenile bigeye tuna (j-BET). The proportion of sharks and billfish as by-catch species, in the landings of HL and PL boats based in Kendari and Sorong was extremely low.

Abstract

As the main target species with high economic value, painted spiny lobster (P. Versicolor) is highly vulnerable to fishing impacts. The study on stock status and biological reference points is needed to develop management strategies for sustainable lobster fisheries in West Papua. This research aimed to understand the stock status, obtain the natural reference points, and set the management tools for P. Versicolor fisheries in West Papua. The length-based assessment of P. Versicolor stock has been conducted to obtain the life history parameters and analyze the yield per recruit and spawning potential ratio. The growth of overfishing has occurred based on the current length at the selectivity of P. Versicolor, which is lower than the optimal selectivity. The indication of recruitment overfishing has been found based on the recent fishing mortality, which exceeds 24% of reference point F40%. A reduction of 24% from current fishing mortality and the minimum legal size of 83 mm is needed to obtain the optimal yield in sustainable conditions.

Abstract

Blue swimming crab fishery in Salemo Island, Spermonde Archipelago, indicates overfishing. To ensure the sustainability of the blue swimming crab fishery, conservation effort through fishing prohibition needs to enforce. This research aimed to design a reservation area to protect the blue swimming crab resources. The study was conducted from May to July 2015. Creating a reserved area requires information on female berried crabs and larval abundance as the basic assumption that places containing the two information are the spawning ground. Information on female berried crabs in Salemo Island is readily available in the literature, while information on larval abundance must be obtained through this study before designing the reservation. Larvae of the blue swimming crabs were sampled using larval nets. Sampling was performed in three habitats: seagrass beds, coral reefs, and mangroves (estuaries). Differences between habitat’s larval abundance were analyzed using a Student T-test, while the reservation area was designed using Marxan Software. Total larvae captured during samplings were 236 individuals. Larvae were abundant in seagrass beds and coral reefs, making the two habitats suitable for the reserved area. The “no-take zone” area obtained from the analysis protects the biological parameters, less conflict with human activities, and provides minimum cost, which is fulfilled by Scenario 3.

Abstract

Tuna and skipjack are large pelagic fish that have high economic value and have a very wide export market. The need for and the high market demand for tuna and skipjack causes the intensity of catching this fish to increase. To ensure that the potential of these fish resources remains sustainable, it is necessary to properly manage fisheries.The purpose of this study was to examine several aspects of biology, aspects of capture fisheries, aspects of utilization and management of yellow fin tuna and skipjack tuna. Data collection for yellowfin tuna was focused on one location, namely PPS Bungus, while data collection for skipjack tuna was focused on 4 location points, namely PPS Bungus, PPP Carocok Terusan, PPI Kambang and PPI Tiku. Productivity and cultivation levels of yellowfin tuna in West Sumatra have tended to decline in the past 4 years (2017-2020). Skipjack tuna in the West Sumatra region caught by boat charters was indicated to be overfishing, while skipjack tuna caught by troll showed the fish caught had not spawned yet. The productivity of skipjack tuna has fluctuated over the past 5 years (2016-2020).
