Abstract

Ikan Ekor Kuning (Caesio cuning) merupakan salah satu target ikan tangkapan nelayan yang didaratkan di Kaliadem yang selanjutnya di jual di Pasar Ikan Muara Angke, Jakarta. Caesio cuning mempunyai nilai ekonomis tinggi dan telah banyak dikonsumsi oleh berbagai kalangan masyarakat. Penelitian ini bertujuan untuk mengetahui hubungan berat terhadap variasi morfometrik Caesio cuning yang menghasilkan pola pertumbuhan ikan. Pengambilan sampel ikan sebanyak 30 ekor dilaksanakan pada bulan April 2018 dengan metode survei di Pasar Ikan Muara Angke. Pengamatan morfologi dilakukan secara tradisional menggunakan penggaris dengan ketelitian 0.01 mm dan ditimbang menggunakan timbangan analitik dengan ketelitian 0.01 gr. Analisa yang digunakan untuk data pengukuran morfometrik dan berat ikan adalah regresi linear berganda. Hasil yang diperoleh bahwa karakter morfometrik secara keseluruhan berpengaruh terhadap berat badan ikan sebesar 98.4%, dimana karakter morfometrik pada panjang mulut (PM) yang berpengaruh positif terhadap berat badan ikan dengan nilai p-value sebesar 0.048 (>0.05), t Stat sebesar 2.113 (>1.96) dan coefficients sebesar 21.843 (+). Angka tersebut dapat diasumsikan bahwa setiap adanya penambahan pada panjang mulut sebesar 1cm maka akan bertambah 21.8gr berat badan ikan dengan kategori pola pertumbuhan alometrik positif.

Abstract

This study focuses on assessing the coastal conditions in Jambi Province both physicochemical and biological parameters. This combination of assessments previously still had limited understanding. Retrieval of physical parameter data using a multi-parameter water quality analyzer, chemical data using the APHA method and spectrophotometer, and chlorophyll-a data using the Copernicus Marine Environment Monitoring Service (CMEMS). The results, with adjustments to national quality standards and pollution index measurements, showed that the five research stations on the east coast of Jambi experienced light to moderate pollution with a score range of 1.252-5.831. Pollution is in the form of nutrients, especially nitrate. However, the trophic index of the coast is classified as oligotrophic, which ranges between 0.689278 - 0.7599 mg/m3. Otherwise, the high nutrient values are TOM and TN, which have a significant correlation, besides the correlation with DO and pH. Measurements of TN and TP in the water column and sediment have also been carried out, where the water column TN concentration is about 5 times higher than the sediment TN and the water column TP concentration is 7 times lower than the sediment TP. The results of this study will contribute to a better understanding of coastal ecosystem health and its significance for the management of the coastal environment in Jambi as a fisheries catchment area.

Abstract

The nilem fish (Osteochilus hasselti) is one of the most easily caught fish in Teluk Lake. Currently, cage farming activity in the lake slightly exceeds the water carrying capacity, which is suspected to affect the life of fish in the lake, including nilem. This study aimed to determine the condition factor and Gonadosomatic Index (GSI) of the nilem catch in the lake. This study was conducted from August to September 2023 in Teluk Lake. This research used a survey method with simple census sampling techniques. The analysis of the length-weight relationship of nilem fish obtained from Teluk Lake showed a positive allometric relationship with a value of b = 3.7148. It showed that the increase in body weight of nilem fish was not linear with the increase in length. The catch results by fishermen for nilem fish found a male-to-female sex ratio of 1:2.15, with 90% of the captured fish in a mature gonad condition. The GSI for females ranged from 3.20% to 8.33% and for males, from 0.03% to 28.89%. The first maturation size (Lm) for male fish was 125.847, with a size class range of 116–126 mm. For female fish, the first maturation size calculation resulted in 112.996 with a size range in the 104–113 mm class. Lm is smaller than the average size of the captured fish, indicating that it is safe to catch, and there is a low likelihood of recruitment overfishing.

Abstract

Mendahara Ilir is an area located on the coast with the majority of the community working as fishermen. Fishermen in this area catch fish using Gillnet fishing gear. Overfishing is a form of excessive fishing, the fish population is decreasing over time so that it can cause extinction and will cause degradation of fish resources leading to the extinction of the Senangin species. The purpose of this study was to determine the morphometric and meristic measurements of Senangin (Eleutheronema tetradactylum) in the waters of Mendahara Ilir which can be used as a consideration in making fisheries resource management policies. The method used in this study was the survey method. Data collection was carried out on 30 Senangin samples. Morphometric measurements used 11 characters and meristic calculations used 7 characters. The results of this study showed that the longest Senangin was 65.8 cm and the shortest was 19.0 cm. The average length of the Senangin obtained was 34.7 cm. The determination coefficient R2 of senangin from morphometric characters to total length (TL) ranges from 0.94 to 0.99 where the value shows a very close relationship. The correlation results are influenced by food availability. Meristics of senangin are D.II; D17-19, A.II: A15-70, P.II: 10-76, C.II: 31-182, scales on the tail stem with a total of 136 and a minimum number of 40, lateral line scales with a total of 170 and a minimum number of 62. The conclusion is that Senangin in the Mendahara Ilir waters are still well maintained habitat in Mendahara Ilir.

Abstract

This community service activity was carried out in Kuala Tungkal, Tanjung Jabung Barat Regency, Jambi Province, to address the challenges faced by fishermen in identifying potential fishing grounds. The primary focus was creating a map of potential fishing grounds based on oceanographic data to enhance the efficiency and productivity of fishermen. The methods included collecting oceanographic data, satellite imagery, and performing geospatial analysis using ArcGIS 10.8 software to predict and map the potential fishing grounds. Training sessions were held to teach fishermen how to use GPS and fishing ground maps, enabling them to predict and navigate fishing locations more effectively. This activity was carried out by involving several participations; fishermen, local government, and Fisheries Service of Tanjung Jabung Barat Regency. The map produced by the team depicts strategic locations in the waters of Kuala Tungkal (FMA 711) based on sea surface temperature (SST) and chlorophyll-a indicators. There are 105,633 potential fishing points being identified in this area. SST values range from 28.2°C to 32°C, and chlorophyll-a values range from 0.2 mg/m³ to 2 mg/m³.  The training outcomes demonstrated that most fishermen could effectively use GPS and the fishing ground map during fishing operations. The active participation of fishermen and the provision of technology training is pivotal in the program’s success. Consequently, the utilization of potential fishing ground maps based on oceanographic data has the potential to enhance fishermen's performance and contribute to sustainable fisheries resource management in the FMA 711 area.

Abstract

Yellowfin tuna is one of the main catches in West Sumatera waters and has a high economic value. Fishing optimization can be improved through spatial and temporal predictions of fishing areas for effective fisheries management. This research aims to predict fishing areas using an oceanographic data approach through maximum entropy (MaxEnt) modelling. Data collection incorporating sea surface temperature and chlorophyll-a were obtained from the Aqua-Modis satellite in 2022 as well as fishing point data from Ocean Fishing Port (OFP) Bungus. The MaxEnt model shows a good level of accuracy in the West season (AUC 0,860), 1st Transitional season (AUC 0,918), East season (AUC 0,918), and 2nd Transitional season (0,920) The contribution of chlorophyll for one year is more significant, accounted for 75,3%, compared to sea surface temperature, constituted 24,7%. The Sea Surface Temperature (SST) values in West Sumatera waters vary on each season, ranging from 26,4 to 34.5 ℃ and the chlorophyll-a fluctuate between 0,03 and 5,45 mg/m3. The distribution of yellowfin tuna habitat on the map shows that most fishing vessel coordinates are in the Habitat Suitability Index (HSI) HSI value of 0,6 – 0,9. Potential areas for catching yellowfin tuna are around the Mentawai Islands. Keywords: Chlorophyll-a, HSI, Maximum Entropy Model, Sea Surface Temperature, Yellowfin Tuna

Abstract

Grouper (Epinephelus Sp.) is an economically important fish that lives in coral reefs and is widely consumed by the public. It is necessary to analyze the relationship between the length and weight of fish at the Kaliadem fish landing site and Muara Angke market. This research aims to determine the relationship between length and weight of fish. Data on the length and weight of the fish were taken from a sample of 20 grouper fish sold at the two locations. This Research was carried out in April 2018. This study used survey method, observation of grouper morphology. The analysis used in this research uses multiple linear regression analysis. The research showed that grouper fish had a length range of 128 mm – 169 mm and a weight range of 31 g – 65 g with an average length of 144.5 mm and an average weight of 42.75. The results of linear regression on the relationship between the length and weight of grouper fish samples produced a regression equation Y = 2.7424x – 9.8972 with a value of b = 2.74 and a coefficient of determination of 0.9281. significant b < 3 means the allomatric growth pattern is negative and 98.97% of changes in fish weight occur due to an increase in fish length, while 1.03% is caused by other factors. It can be concluded that length growth is faster than weight gain in grouper fish. The condition factor value of the grouper this research had a Fulton condition factor value (K) ranging from 2.95 to 3.17 and a relative weight (Wr) ranging from 86.50 to 106.41 with an average Wr value of 100.31.

Abstract

Anchovy is one of potential commodities widely found and caught by fishermen in FMA-572 West Sumatra. Examining its exploitation rate is a part of taking control and monitor toward the fishing activities to avoid overfishing possibility. This recent study aims to calculate exploitation rate and oceanographic characteristics of anchovy fishing grounds. The data was collected from Bungus Oceanic Fishing Port, West Sumatra in 2018-2022. Meanwhile, sea surface temperature and chlorophyll data were obtained from https://marine.copernicus.eu/ and https://oceancolor.gsfc.nasa.gov 2018-2022, respectively. The results showed that the exploitation rate of anchovies in 2020 and 2022 has exceeded maximum sustainable yield categorized as overexploitation with a percentage of 130.44% and 112.84%. Anchovy catches are significantly influenced by oceanographic factors with F value 0.00000115 ( 0.05). An increase in CPUE value is align with chlorophyll increase and in contrary to sea surface temperature. The findings are expected to give an overview related to anchovy fishing activities implementation and become an input for fisheries governance that lead to sustainable fisheries management.Keywords:FMA-572MSYOverfishingSustainable fisheriesStolephorus sp
