Abstract

The use of Geographic Information Systems (GIS) to generate digital data that provides information on the characteristics of an area and describes changes in land cover that can be used in a more effective and efficient sustainable manner. This study aims to analyze the mangrove land cover of the north coast of Aceh Besar over the last three decades, namely 2000, 2010, and 2020 in the Baitussalam sub-district, Mesjid Raya sub-district and Seulimeum sub-district. The research was conducted from June 2022 to September 2022 at the GIS Laboratory, Faculty of Marine and Fisheries, Syiah Kuala University. The research was conducted using a Geographic Information System (GIS) that utilizes high-resolution satellite imagery from Google Earth Pro. Mangrove land was digitized visually on screen, then data processing was carried out, and spatially analyzed. The results of the analysis of changes in mangrove land cover in the research area show that the Baitussalam and Mesjid Raya sub-districts had a decreasing trend of mangove land between 2000 and 2010 and subsequently there was an increase in mangrove land cover from 2010 to 2020. Meanwhile, Seulimeum sub-district experienced a decreasing trend of land cover in 2000 until 2020. The decline in the trend of mangroves in various places is caused by the growth of the population using mangrove land as residential area. While the increase in mangove land cover was due to the success of reforestation and pond land conversion. The results conclude that the mangrove land cover on the north coast of Aceh Besar is relatively stable with an increasing trend of growth.Keywords:Land coverMangroveHigh resolution googleHistorical imageryGoogle earth proDigitize

Abstract

Violet Batissa (Batissa violacea) is an important economic organism on the west-south coast of Aceh, because it is relatively high consumed by the community. However, gold mining activities carried out around the watershed are estimated to pollute the river and cause B. violacea to also be affected. The purpose of this study was to determine the level of mercury (Hg) and Lead (Pb) contamination in clam meat in Teunom, Aceh Jaya Regency. The research was conducted from June to September 2021. Sampling of clam was done by purposive sampling method. Hg and Pb were analyzed in clam meat using the Atomic Absorption Spectrophotometer (AAS) method. The results of the analysis showed that the Hg content in clam meat was between 0.12-0.63 mg/kg (mean 0.35±0.26 mg/kg), water 0.0026-0.0103 mg/kg (mean 0.0052±0.004 mg/kg), and sediment 1.3224-3.8767 mg/kg (mean 2.2324±1.427 mg/kg). Furthermore, the results of the analysis showed that the Pb content in clam meat, water and sediment had the same value at 3 stations with values 0.0002±0 mg/kg, 0.0003±0 mg/kg, and 0.0002±0 mg/kg, respectively. The conclusion of this study is that the Hg content in water and sediment has exceeded the threshold, while the clam meat is still in good quality standards. The Pb content in clam meat, water and sediment were also in good quality standards. Based on our study, B. violacea is still safe for consumption, while the water has been polluted and is recommended not to be utilized for human consumption.Keywords:Heavy metalRiverWaterSedimentBatissa violacea

Abstract

Batu Bara Regency is a region with abundant natural resources, one of which is the cultivation of grouper fish. Grouper is a member of the Serranidae family of coral reef fish. Many groupers are raised in ponds, which makes them susceptible to disease due to environmental and dietary factors that are not adapted to grouper fish, which is a native species. Parasites are one of the grouper-infecting diseases that, if left untreated, can result in mass mortality and harm farmers. The aim of this study was to identify parasites in ponds in Mesjid Lama Village, Talawi District, so that it would be easier to determine the type of parasite, its level of attack, and subsequent efforts to eradicate it. This research employs a sampling technique, specifically a random sampling of orange-spotted grouper. The results of the performed analysis include analyses of both ectoparasites and endoparasites. Several types of ectoparasites were identified, including Cryptocaryon irritans, Pseudorhabdosynochus sp, Benedenia epinepheli, and Caligus sp, while Prosorynchus sp was identified as the endoparasite. The most prevalent parasite found in the fish is Cryptocaryon irritans.Keywords: EndoparasiteParasitesGrouper

Abstract

The waters of Palabuhanratu Bay are fertile and rich with fish resources. For a long time, fishermen have used the fish resources in these waters. Hairtail (Trichiurus sp.) was one of the fish resources in Palabuhanratu Bay that caught by fishermen using handlines. Fishery production landed at Palabuhanratu Fishing Port in 2019 was 5,414,240 kg with a total hairtail production of 314,107 kg. The problem raised in this study was knowing the right hairtail fishing season so that it provides optimum benefits for fishermen. In addition, knowing potential fishing areas could assist fishermen in choosing their fishing time and fishing ground. The purpose of this study was to describe the hairtail fishing unit, to analyze the catch composition of handline, to analyze the fishing season patterns of hairtail fish, and to analyze hairtail fishing ground in Palabuhanratu bay. The results of the analysis showed that the fishing season for hairtail (Trichiurus sp.) in the waters of Palabuhanratu Bay lasts for 5 years with the peak in October. However, the reality is that fishing operations can be carried out throughout the year. The average catch per unit effort (CPUE) of hairtail (Trichiurus sp) duringfishing seasons was 11.32 kg/trip in 2019. The potential fishing ground was in the waters of West Ujung Genteng, Southern waters of Sawarna, Southern waters of Karanghawu and the waters of West Ujung Karang Bentang.Keywords:Fishing season patternHairtail fishFishing groundPalabuhanratu Bay

Abstract. The objective of the present study was to analyze the budgetary trends and the effectiveness of fisheries subsidies in Aceh Besar district. The literature and survey methods were utilized in this study. The secondary data of Aceh Besar’s budget documents in the period of 2010-2012 and key person interviews with fishermen leaders were conducted to analysis the subsidy trend and fishermen perception. The data was collected in May through July 2012. The results showed the budget allocation to the fisheries sector were increased from year to year, in 2010 the total budget for the fisheries sector was Rp1, 9 billions (equivalent to 0.34% of total buget or 1.40% of the development budget allocation/indirect consumption), in it was increased to Rp2, 9 billion in 2011 (or 0.42% of total budget or 1.47% of the development budget allocation), then increased sharply in 2012 to Rp9, 2 billion (an increase of over 630%) from the previous year, equivalent to 1.11% of the total budget. In 2010, the proportion of subsidies were given mostly for aquaculture sub-sector, which reached 84% of the total budget that was managed by the Department of Marine and Fisheries of Aceh Besar, whereas in 2011 the proportion of subsidies occurred balance between aquaculture and capture fishery sub sectors. However, in 2012 most of the budget DKP Aceh Besar (63%) was allocated to the capture fishery sub-sector. The results of the study showed that fisheries subsidies by the Government of Aceh Besar district especially in the last two years have not yet met the criteria of sustainable fisheries subsidies.

Abstract

Siganid is better known as rabbit fish. In hatcheries, constraint that is still faced is the low survival, which was assumed to occur because of the timing for initial feeding is not solidly known. This research aimed to examine the best initial feeding time for siganus, based on evaluation on eyes and yolk reserves during the transition. The research was conducted from 24-29 March 2021 in IPUW Barru, South Sulawesi. Larvae were obtained from the second progeny (G2) of domesticated Siganus guttatus. Larvae were reared for 5-6 days without feeding. Evaluated parameters include eyes diameter and yolk reserves. Samples were observed with microscope and will be explained descriptively. Water quality parameters were measured, namely DO, salinity, pH and temperature. Eyes diameter at 6 Hour After Hatching (HAH) ranges between 81.5-128.9 µm, 13 HAH= 125.5-167.7 µm, 24 HAH= 138.2-213.9 µm, two days after hatching 2 Day After Hatching (DAH) = 113.6-193.1 µm, 3 DAH= 163.1-219.2 µm, 4 DAH= 190.4-212.6 µm. Yolk reserves diameter ranged between 137-194µm (6 HAH), 13 HAH= 152-191µm, 24 HAH= 94.0-185µm, 2 DAH= 75.3-99.63µm, 3 DAH= 42.33-87.58µm, 4 DAH= 38.17-55.59µm. After age 5 DAH, there are no larvae found alive (dead). Eyes developed at age 6 HAH and experienced pigmentation at age 24 HAH. Conversely, yolk reserves diameters were getting smaller since age 24 HAH and completely disappear at age 4 DAH. It indicates that eyes effectively see feeds at age 2 DAH. Therefore, initial feeding should be started. The water quality parameters measured were still in normal conditions according to the life of S. guttatus larvae. From this research, it can be concluded that eyes have been well functioned at age 2 DAH and yolk reserves was finished at age 4 DAH. Therefore, the initial feeding should be done at the age of 2 DAH.Keywords:Development, Siganus guttatus larvae,Transition
