Abstract

A biological reference point is a term used to explain of stock status using a biological approach as a basic of fisheries management. Biological reference points of painted spiny lobster Panulirus versicolor are limited in Karimunjawa waters. This study aims to investigate the stock status of P. versicolor and management options to ensure the sustainability of the resources. The research was conducted in Karimunjawa islands of the Java Sea by collecting lobster from local fishers from March to November 2016. A total of 495 lobster were measured, weighed, and their maturity status assessed to allow the size at maturity and selectivity of the fishery to be estimated. The size at maturity L50 (62.2 mm CL) and L95 (82.0 mm CL) were larger than SL50 (48.2 mm CL) and SL95 (75.0 mm CL), respectively. Natural mortality (M) which was 0.579 year-1 is lower than fishing mortality (F). The current spawning potential ratio (SPR) of P. versicolor is 19% at the current F of 0.82, which is below SPR limit of 20% and target reference point of 40%. Hence, to increase SPR level to 40%, the fishing mortality should be reduced by about 40% to 60%. Closed season, legal size, and defining no take zone are options to consider by fishery manager with appropriate surveillance control. Single or combining those measures can reduce its fishing mortality and take back the stocks to the level of target reference point.

Abstract

Southern Bluefin Tuna in spawning area of the Eastern Indian Ocean where the Indonesian?s longliners operated has a specific character in term of size, age, sex-specific growth rate and the population. The aims of this study are to determined changes in size/age, sex-specific growth rate and virtual population analysis of Southern Bluefin Tuna (SBT) in the spawning area. This study is important to find out the successful management of SBT in spawning area by looking at the catch at age/size movement, sex-specific growth analysis and the estimation of the population by virtual population analysis. In this study, we were used 452 pairs of otolith with fish sized from 134-196 cmFL and fish aged from 8-20 years. The growth equation was Lt = 191 (1-e-0,167(t+1,081)). Catch at age structure was distributed from 5-22 years with mean and mode of age were 9.63 and 9 years. The distribution of mode changed from year to year shifting to a younger fish. In 2012, the mode was 10 years but entering 2013-2014 the mode was shifted to 6 years. In 2015-2017, the mode was increased from 7 years (2015) to 8 years (2016) and 9 years (2017). The fishing pressure happened in the age group under 20 years. In 2012 to 2014, the highest fishing pressure respectively obtained in the age group of 13 to 11 years with an average length of 167 to 174 cmFL. Entering 2015 and 2016, the highest fishing pressure obtained in the age group of 6 years with an average length of 138 cmFL. The exploitation rate ranged from 0.14/year to 0.25/year meaning that the exploitation was in optimal condition.

Abstract

Bordered with the Indian Ocean, Simeulue Islands is one of the outermost islands in Indonesia located in the west part of Aceh Province. Simeulue waters are productive areas due to the unpolluted condition yet and great of biomass. Three regions were particularly observed, those are Simeuluecut, Ganting, and Labuhan Bajau. In those areas, the existing marine tourism activities might influence the coral reef ecosystem studied. This study aimed to evaluate the condition of coral and coral reef fish in those three particular regions before mass bleaching event in 2016 triggered by ENSO. Point Intercept Transect (PIT) method was employed to record the percentage cover of coral, species diversity, and coral reef fish. Ganting waters was a moderate ecosystem area whith the percentage coverage was up to 45.62%. However, in Simeuluecut and Labuhan Bajau waters, the coral reef communities were excellent with coral percentage coverage reached 83.12% and 81.25 %, respectively. The highest  abundance genera of coral reef fish was observed in Simueluecut waters. This condition was changed oppositely in 2016 when mass bleaching threatened Simeulue waters due to temperature anomaly triggered by ENSO phenomenon. The temperature increases almost 3oC for 6 months that undoubtedly induced bleaching that about 50% of coral colonies were dramatically declined in coral coverage and coral recruitment.

Abstract

This study aimed to determine the growth patterns, mortality, and exploitation status of two species of Alestidae in the New Calabar River, Nigeria. For this purpose, fish samples were collected monthly from three landing sites from the local fishermen using gill nets (mesh sizes: 15-25mm), beach seine (mesh sizes: 2.3-10mm), and cast nets (mesh sizes: 15 -25mm). The length-weight relationship revealed exponent ?b? value for Brycinus nurse was 3.54 and 3.21 for Brycinus macrolepidotus while the condition factors were 1.08 and 1.02 for Brycinus nurse and Brycinus macrolepidotus respectively. The growth parameters of Brycinus nurse asymptotic length (L) and growth coefficient (K) were 24.46 cm and 0.52 yr-1, respectively, while those for Brycinus macrolepidotus L was 28.88 cm and K was 0.22 yr-1. The reproductive load (L50/L) ratio was found to be 0.59 and 0.61 for B. nurse and B. macrolepidotus, respectively. Exploitation rate (E) for B. nurse was 0.26 and 0.11 for B. macrolepidotus while length-at-first capture (Lc) was 14.49 cm for B. nurse and 17.64 cm for B. macrolepidotus. The natural mortality was greater than the fishing mortality for both species and Logistic regression of the probability of capture routine values recorded for B. nurse were higher than that of B. macrolepidotus. Maximum exploitation rate (Emax) was less than 0.5 for both B. nurse (0.41) and B. macrolepidotus (0.42). These values were close to the maximum allowable limit; therefore, the species may be unsustainable when fishery intensifies in the future. To ensure sustainable exploitation of the two Alestid species in the area, fishing effort should be regulated.

Abstract

Rumpon (fish aggregating device) as an auxiliary gear operated in Pasauran waters, Sunda Strait was longer and more widely used in Indonesia to catch pelagic fish. The characteristic speciescomposition, size, and gonado somato index (GSI) pelagic fish around 3 kinds of rumpon attractor materials, i.e. Cocos nucifera, Nypa fructican, and Areca catechu leaves will determine the effects of attractor materials will affect the sustainability of pelagic fish associated. Identification and composition length, weight and gonado somato index pelagic fish were identified in this research with different attractor material in all seasons. Experimental fishing carried out by using payang Bugis. The result show that the Cocos nucifera leaves are the best attractor material based on the number of fish species and durability in all seasons. Further, the gonado somato index of small pelagic fish were caught around rumpon are gonado somato index I 4%, gonado somato index II 33%, gonado somato index III 35%, gonado somato index IV 25%, and gonado somato index V 3%. Pelagic fish around attractor materials have gonado somato index I-III 72%. This result indicated that the small pelagic fish caught around rumpon are immature fish.

Abstract

The objective of this research is to determine patterns of interaction between fishers and foreign investors (Malaysia) in the fishing business. Research conducted on May 2009 in the Nunukan, East Kalimantan. The data retrieval was conducted by in depth interviews (deep interviews) with the fishersand middlemen as well as direct observations on the condition of the fishing business and marketing in both the Nunukan District and in Tawau Malaysia. The results showed that there is a relatively large dependence of the fishers in Nunukan District to the owners of capital from Tawau regarding capital provision, marketing of the catch, and social security.

Abstract

The slimeheads (Hoplosfefhus spp.) provide one of the likely economic important deep sea demersal fish resources in the near future. The fish was caught in western part of Sumatera, in the depth of more than 500 m deep, and was found in substantial amount in the deep waters around Simeuleu lsland and the western off Banda Aceh. Data analysis was limited to the biological aspects, including length relationship, and maturity.
