<p>ABSTRACT<br /><br />Indian mackerel is one of the small pelagic fish that has an important economic value and the dominant fish catches landed in PPP Labuan. The catch of Indian mackerel decreaseyear to year. Therefore Indian mackerel resources, alleged have over-exploited. The aim of this research was to identify a production pattern, fishing ground, fishing season pattern and identify a more appropriate alternative recommendation for the management of Indianmackerel. The results showedthat the production of Indian mackerel had a fluctuated seasonal pattern. The peak fishing season was in April to August while low season (low catches) in December and January. Distribution of Indian mackerel fishing grounds wasin the waters around the Sunda Strait such as RakataIsland, Rakata Kecil Island, Anak RakataIsland, Panaitan Island, Papole Island, Sebesi Island, Sebuku Island, Jongor and Tanjung Lesung. Utilization status of Indian mackerel has already overfished in biology and economics. Some recommendation for managing Indian mackerel resources that were landed in PPP Labuan such as, reduce the fishing effort, increase the mesh size, and improvementmanagement infishing season and fishing ground.<br /><br />Keywords: Indian mackerel, management, PPP Labuan, Sunda Strait</p><p>-------<br />ABSTRAK</p><p><br />Ikan kembung merupakan salah satu ikan pelagis kecil yang memiliki nilai ekonomis penting dan merupakan ikan tangkapan dominan yang didaratkan di PPP Labuan.

<p>ABSTRACT<br />Fringescale sardinella (Sardinella fimbriata) is one of the economically important fish resources found in Sunda Strait waters. High economic value with the increasing demand of fish makes it as one of the main targets of capture. Intensive utilization on fringescale sardinella resulted in overfishing. The aim of this research is to identify production pattern, fishing ground, fishing season pattern and appropriate alternative management. This research carried out on April to June 2014. The results show that fringescale sardinella has a fluctuated production pattern. Fishing season for fringescale sardinella is on May-October, while the fringescale sardinella bad season (low catches) is on March. Fishing ground for fringescale sardinella in Sunda Strait waters are Labuan Bay, Tanjung Lesung, Sumur, Panaitan Strait, Rakata Island, Ujung Kulon, Sebesi Island, Tanjung Alang-alang, and Peucang Island. Management for fringescale sardinella can be accomplished by increase the mesh size, management fishing season (open-close system) and fishing areas.</p><p><br />Keywords: Fringescale sardinella, management, PPP Labuan, Sunda Strait</p><p>-------</p><p><br />ABSTRAK</p><p>Ikan tembang (Sardinella fimbriata) merupakan salah satu sumberdaya ikan ekonomis penting di perairan Selat Sunda.

Kwandang waters is one of the main base for small pelagic fisheries in Sulawesi sea in which the Indian mackerel  (Rastrelliger kanagurta) has been exploited. The objective of the research was to estimate the population parameters, exploitation rate and reproductive biology of Indian mackerel. Length frequency data were collected from PP Kwandang, between February and October 2012. Estimation of population parameters of Indian mackerel was done using FISAT II method. The results showed that growth rate as follows (K) = 0,80 year-1 , L∞=27,3 cm.  Total mortality rate (Z) = 2,72 year-1, with natural mortality (M) = 1,29 year-1 and fishing mortality (F) = 1,43 year-1 and exploitation rate (E)=0,53. Exploitation of Indian mackerel in Kwandang waters have reached its optimum level. The sex ratio of Indian mackerel was balance. The most commonly found is Gonado Maturity Stage of I. Based on the results, it is necessary to manage with  the responsible management through gradually increasing of the mesh size of the gears or restricting additional lift net or  by restricting fishing for certain seasons or declaring fish sanctuaries in certain areas, especially in spawning grounds to protect the Indian mackerel.

Abstract Jensen, H., Rindorf, A., Wright, P. J., and Mosegaard, H. 2011. Inferring the location and scale of mixing between habitat areas of lesser sandeel through information from the fishery. – ICES Journal of Marine Science, 68: 43–51. Sandeels are small pelagic fish that play an important role in the diet of a range of natural predators. Because of their limited capture by traditional survey gear, little is known about their large-scale distribution or the degree of mixing between habitat areas. Detailed information collected directly from the fishery was used to map fishing grounds, which were then assumed to reflect the foraging habitat of the species. Length distributions from individual hauls were used to assess differences in the distributions as a function of distance between samples. Sandeel foraging habitat covered some 5% of the total area of the North Sea. Mixing between neighbouring fishing grounds was too low to eliminate differences in length distributions at distances between grounds down to 5 km. Within fishing grounds, mixing was sufficient to eliminate differences in length distributions at scales <28 km but insufficient at greater distances. The lack of mixing between grounds may result in large differences in sandeel abundance among adjacent fishing grounds. Further, notable abundance at one end of an extensive fishing ground is not necessarily indicative of similar abundance at its other end.

Fishing resources are important generators of income and food for the rural and urban people in the Amazon. The present paper investigates fishing and environmental variables determining fishing production landed in Manaus and evaluates the relative abundance of commercial fishes in the different sub-systems of the Central Amazon basin. Information collected was used to test the new catch index derived from multiple regressions with the following significant variables: number of fisherman days fishing; distance of the fishing ground from Manaus; amount of ice carried during the trip; and river level. There were no significant differences between mean catch values of the Purus, Madeira and Juruá sub-systems. These results suggest that the tributaries of the right margin were very similar and were the most productive in commercial terms. The actual production varies according to the recent magnitude of fishing effort, environmental variations and operational aspects of fishing, particularly ice consumption.

AbstractFisheries have global socioeconomic and ecological effects. Long-term ecological studies could be beneficial to ecosystem approach management and biodiversity conservation, however, they are rare. In this study, the impacts of bottom trawling on a traditional fishing ground in the Eastern Mediterranean were addressed and an improvement in diversity metrics and ecological quality status were detected and ascribed to the Greek economic crisis. After 18 years, there was a modest increase in species richness, total abundance, and ecological status in the unaffected zone and more pronounced improvement in the trawled zone pointing at a possible link to a decrease in fishing effort. This upturn emphasized the strong link between financial activities and ecology. The present study underlines the multiple and variable effects of economy not only on countries and citizens but also on the environment and ecosystem conservation and management.

Many species of marine organisms live in Indonesian waters have a potential for aquaculture (fishes, crustaceans, mollusc, echinoderm, and algae). They are cultured for food resources, the basis for cosmetic and natural medicine, and also as ornamental fish for marine aquarium. Seahorse (Syngnathidae: Hippocampus) is a marine fish which has high ecological and economic value. Fishing pressure of wild seahorse increased significantly when buyers offering an attractive price for the catch. High levels of fishing effort keep the wild stocks of seahorses well below the level that could be supported by natural growth and recruitment. Aquaculture for seahorses is very important to support sustainable production and to maintain the wild population in steady condition. Culture technique for seahorses has been developed in some countries, including Indonesia. However, seahorse aquaculture in Indonesia has not been achieved as expected due to the limited understanding of some biological characteristics. This manuscript deliberates some biological characteristics that useful as basic knowledge for seahorse aquaculture.

Biodiversitas 19: 2275-2282. This investigation was conducted to determine the bycatch composition of cutlassfish (Trichiurus lepturus) trawlers in Bushehr and Hormozgan waters during fishing season 2013. Data collection was carried out in the summer for Bushehr and in the autumn for Hormozgan province for one month. All trawler vessels were equipped with a 36 m head rope and 75 mm stretched mesh size in the codend and 90 to 200 mm stretched mesh size in the panel. 47 species included 35 species of teleosts, 9 species of elasmobranches and 3 species of invertebrates were identified in Bushehr. Also, 48 species included 38 species of teleosts, 7 species of elasmobranches and 3 species of invertebrates were identified in Hormozgan. The weight and numerical averages of bycatch species were 25.41 (kg h-1) and 205.9 (n h-1) in Bushehr, and 92.58 (kg h-1) and 440.4 (n h-1) in Hormozagan. I. megaloptera, S. tumbil, N. japonicus, D. acuta, C. sexfasciatus, L. equulus in Bushehr and P. sextarius, I. megalopteran, M. cinereus, P. macrophthalmus, N. japonicus and S. tumbil in Hormozgan had highest catch weight. Based on the weight and number, PCA and nMDS methods were indicative of two different assemblages in hunting places. Furthermore, ANOSIM similarity analysis confirmed the results of PCA and nMDS and showed a significant difference in the catch composition of two fishing zones.
