Fuad, Baskoro M. S., Riyanto M., Mawardi W., 2019 Catch Characteristics on Stationary Lift Net Using Light Emitting Diode (LED) and Kerosene Lights in Pasuruan Waters
Catch characteristics on stationary lift net using light emitting diode (LED) and kerosene lights in Pasuruan waters 1Fuad, 2Mulyono S. Baskoro, 2Mochammad Riyanto, 2Wazir Mawardi 1 Faculty of Fisheries and Marine Science, Brawijaya University, Malang, Indonesia; 2 Marine Fisheries Technology, Faculty of Fisheries and Marine Science, Bogor Agricultural University, West Java, Indonesia. Corresponding author: [email protected] Abstract. Light in stationary lift nets (SLN) is important to the extent that it can determine the composition of species, size and number of fish caught. Different types of light are often used in aggregating certain types of fish. This study aims to find the best type of light for SLN and to determine the characteristics of the catch between light emitting diode (LED) and kerosene lights. The results showed that there were no significant differences in species composition of fish caught in both LED and kerosene lights. These types of lights do not affect the composition of fish species, but have a significant effect on the amount of catch. The most caught fish (target species) were short mackerel (Rastrelliger brachysoma) and yellowstripe scad (Selaroides leptolepis). The SLN operated with kerosene lights caught short mackerel (R. brachysoma) and yellowstripe scad (S. leptolepis) of bigger size compared to SLN with LED lights. The average length and weight of short mackerel caught with kerosene lights were 146.3 mm and 37.17 grams, respectively. The average length and weight of yellowstripe scad (S. leptolepis) caught with kerosene lights were 117.04 mm and 21.5 grams, respectively. However, only a small portion of catch, 4.5%, had already reached its mature size (Lm), while the rest of the catch (95.5%) had not reached its mature size. -

Manojkumar Calicut Research Centre of Central Marine Fisheries Research Institute,West Hill, Calicut – 673005, India. E-mail: [email protected] Abstract Food of the threadfin bream Nemipterus mesoprion from the fishing grounds off Malabar coast were studied based on 3361 specimens. The studies showed that the fish is a demersal carnivore, subsisting mainly on crustaceans, teleosts, molluscs, polychaetes and miscellaneous food items. The trophic spectrum of N. mesoprion composed of 26 food items. Fish in all size groups preferred crustaceans. Penaeid prawns, Acetes spp. and deep-sea prawns were the dominant crustaceans in the diet. Anchovies, scads, lizardfishes and whitefish were the teleosts that formed the major diet component. N. mesoprion showed preference for teleosts as they grew. Copepods, crabs and squilla were seen mostly in the stomach of juveniles and pre- adult fishes. Teleosts were the major food during January-March and in all the other months crustaceans were dominant in the food. Feeding intensity was poor during most of the months.

Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗
Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗ I examine the estimated economic, ecological, and food security effects of future fishery management reform in Asia. Without climate change, most Asian fisheries stand to gain substantially from reforms. Optimizing fishery management could increase catch by 24% and profit by 34% over business- as-usual management. These benefits arise from fishing some stocks more conservatively and others more aggressively. Although climate change is expected to reduce carrying capacity in 55% of Asian fisheries, I find that under climate change large benefits from fishery management reform are maintained, though these benefits are heterogeneous. The case for reform remains strong for both catch and profit, though these numbers are slightly lower than in the no-climate change case. These results suggest that, to maximize economic output and food security, Asian fisheries will benefit substantially from the transition to catch shares or other economically rational fishery management institutions, despite the looming effects of climate change. Keywords: Asia, climate change, fisheries, rights-based management JEL codes: Q22, Q28 I. Introduction Global fisheries have diverged sharply over recent decades. High governance, wealthy economies have largely adopted output controls or various forms of catch shares, which has helped fisheries in these economies overcome inefficiencies arising from overfishing (Worm et al. 2009) and capital stuffing (Homans and Wilen 1997), and allowed them to turn the corner toward sustainability (Costello, Gaines, and Lynham 2008) and profitability (Costello et al. 2016). But the world’s largest fishing region, Asia, has instead largely pursued open access and input controls, achieving less long-run fishery management success (World Bank 2017). -
Data Collection and Size Sampling on Neritic Tuna Fisheries in Andaman
IOTC–2018–WPNT08–15 Data Collection and size sampling on Neritic Tuna Fisheries in Andaman Sea Kanokwan Maeroh, Sichon Hoimuk, Suchart Inthong, and Supachai Rodpradit Upper Andaman Sea Fisheries Research and Development Center (Phuket) 77 Moo 7 Vichit Sub-District, Muang District, Phuket Province 83000 Tel. 0 7639 1138-40 e-mail: [email protected] Abstract In the Andaman Sea Coast of Thailand, there are many kinds of fishing gears can catch neritic tuna but most of it were caught by purse seine. The other gears are Otter board trawl, Anchovy falling nets and Squid Falling nets. There are 3 organizations along Andaman sea under Marine Fisheries Research and Development Division responsible to collect the data on fish composition and size distribution, especially for neritic tuna and others importantly economic fish, from more than 10 types of fishing gears. All kind of fishing gears in which both commercial and artisanal fisheries were conducted fisheries data for 3-5 days a month. There are 7 organizations along Andaman sea under Fishing and Fleets Management Division responsible to collected fishing data from logbook and catches landing of marine fish, to recorded and reported the data to Fishing-Info data base. Study on CPUE and MSY were conducted by Fisheries Statistics Analysis and Research Group and Fisheries Resources Assessment Group which are under the Department of Fishery. The purse seine is the mainly fishing gear for pelagic species. Pair trawls and otter board trawls are the main fishing gears for demersal species. The other gears which have a specific name to target species, such as gill nets, hand line and long line. -

The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries.

Journal of Agricultural and Marine Sciences Vol. 20 (2015): 47-53 Reveived 5 May 2014 Accepted 19 Feb 2015 RESEARCH PAPER Protein resources and aquafeed development in the Sultanate of Oman Stephen Goddard 1* and Fahad Saleh Ibrahim 2 موارد الربوتني وتطوير أعﻻف اﻷحياء املائية يف سلطنة عمان ستيفن جودارد1* وفهد صاحل ابراهيم2 Abstract. The continued growth of intensive aquaculture is dependent on the development of sustainable protein sources to replace conventional fish meals in aquafeeds. Practical alternatives are plant-derived protein, protein from micro-organisms and protein from under-utilized marine resources. The challenges are to find alternative ingredients with high protein, suitable amino acid content, high palatability and absence of anti-nutritional factors. There is consid- erable biotechnology-based research in this area, including genetic modification of plant-based proteins, use of probi- otics to enhance digestibility and the renewed application of fermentation technologies to produce single cell proteins. Research in Oman is focused on the utilization of marine protein resources. Fisheries by-catch and processing waste have been evaluated as liquid hydrolysates and as meals for inclusion in aquafeeds and new research is planned on the utilization of meso-pelagic fish (myctophids), which occur in abundance in the Arabian Sea and the Sea of Oman. Initial studies have been conducted on the biochemical composition of the lantern fish,Benthosema pterotum, which revealed favorable protein, amino acid and long-chain PUFA content. Potential limiting factors were high levels of saturated lipids and the heavy metals arsenic and cadmium. These results will be discussed within a general review of marine resources and aquafeed development in Oman.
