Abstract

The fishing gear operated by fishermen along the coast of Grajagan Beach to catch fish is a bottom gill net, using different mesh sizes of 3, 4, and 6 inches. The method used in this study was the Experimental Fishing method, which involved direct observation over nine repetitions using different mesh sizes. Observations were conducted on the quantity of fish caught, and direct interviews were carried out with fishermen regarding the use of gill nets at Grajagan Beach, Banyuwangi, East Java. The composition of the catch showed that the largest proportion by weight was shovel-nosed ray, accounting for 15%, while lobster represented the highest number of individuals caught, at 12%. To determine whether there was an effect of mesh size on the catch yield, an ANOVA test was conducted and produced significant results, indicating that differences in mesh size significantly influenced the catch. In this study, a follow-up (Post Hoc) test was also performed using Tukey’s Honest Significant Difference (HSD) test. The results of the post hoc test showed that the use of a 6-inch mesh size had a substantial effect on the catch yield.

Abstract

This study aims to analyze the level of environmental friendliness of purse seine fishing gear used by fishermen landing their catches at the Ocean Fishing Port (PPS) Cilacap, Central Java. Environmentally friendly fishing gear is an essential component in achieving sustainable fisheries management, as it can minimize negative impacts on marine ecosystems and ensure the sustainability of fish resources. Purse seine is known as a highly efficient fishing gear for catching pelagic fish; however, its potential environmental impacts, such as bycatch, habitat degradation, and overexploitation, require further assessment. The research methods included field observations, interviews with fishermen, and secondary data analysis from relevant institutions, using indicators based on the FAO Code of Conduct for Responsible Fisheries (CCRF) to evaluate environmental friendliness aspects. The results of this study are expected to illustrate the extent to which the use of purse seine at PPS Cilacap meets the criteria of environmentally friendly fishing gear, as well as to provide recommendations for more sustainable capture fisheries management. This research is expected to serve as a reference for the government and stakeholders in formulating policies on the use of effective, equitable, and environmentally friendly fishing gear.

Abstract

Ikan mas (Cyprinus carpio) merupakan salah satu komoditas perikanan budidaya air tawar yang memiliki peran strategis dalam mendukung produksi perikanan nasional dan perekonomian masyarakat. Tingginya intensitas budidaya serta aktivitas lalu lintas ikan hidup antarwilayah meningkatkan risiko penyebaran penyakit ikan, khususnya penyakit viral yang bersifat sangat menular. Salah satu penyakit viral yang menjadi perhatian serius adalah Koi Herpes Virus (KHV), karena dapat menyebabkan tingkat mortalitas yang tinggi dan berdampak signifikan terhadap produksi, ekonomi, serta kelancaran perdagangan ikan. Penelitian ini bertujuan untuk mendeteksi keberadaan Koi Herpes Virus (KHV) dan menentukan tingkat prevalensinya pada komoditas ikan mas (Cyprinus carpio) yang dilalu-lintaskan di Balai Karantina Hewan, Ikan dan Tumbuhan Sulawesi Utara menggunakan metode Real Time Polymerase Chain Reaction (qPCR). Penelitian ini menggunakan desain deskriptif dengan pendekatan surveilans. Sampel penelitian berupa lima ekor ikan mas yang berasal dari kegiatan lalu lintas karantina. Deteksi KHV dilakukan melalui tahapan ekstraksi DNA dan amplifikasi target gen virus menggunakan metode qPCR, sedangkan tingkat prevalensi dihitung berdasarkan perbandingan jumlah sampel positif terhadap jumlah total sampel yang diperiksa. Hasil penelitian menunjukkan bahwa dari lima sampel ikan mas yang diperiksa, satu sampel terdeteksi positif Koi Herpes Virus (KHV), sedangkan empat sampel lainnya menunjukkan hasil negatif. Berdasarkan hasil tersebut, tingkat prevalensi KHV pada ikan mas yang dilalu-lintaskan di Balai Karantina Hewan, Ikan dan Tumbuhan Sulawesi Utara sebesar 20%. Temuan ini menunjukkan bahwa meskipun sebagian besar ikan yang dilalu-lintaskan berada dalam kondisi negatif KHV, potensi masuk dan tersebarnya virus melalui lalu lintas ikan masih tetap ada. Dapat disimpulkan bahwa metode Real Time PCR (qPCR) efektif digunakan sebagai metode deteksi dini Koi Herpes Virus (KHV) karena memiliki sensitivitas dan spesifisitas yang tinggi. Keberadaan KHV pada sebagian sampel ikan mas yang dilalu-lintaskan menegaskan pentingnya penguatan pengawasan karantina ikan serta pelaksanaan pemeriksaan laboratorium secara konsisten sebagai upaya pencegahan penyebaran penyakit ikan ke wilayah lain, sebagaimana direkomendasikan dalam sistem karantina ikan nasional.

Abstract

Guppy fish (Poecilia reticulata) hold high commercial value, particularly the males, due to their aesthetic colors and morphology. This study aims to determine the effect of different soaking durations in honey on the masculinization of guppy larvae and to identify the optimal immersion time. This experimental study utilized a Completely Randomized Design (CRD) with 5 treatments and 5 replications, using a honey dosage of 5 ml/L with soaking durations of: 8 hours, 10 hours, 12 hours, 14 hours, and 16 hours. The results showed that the variation in soaking duration had a significant impact on the percentage of masculinization. The 12-hour soaking treatment yielded the best results, achieving a male percentage of 90.1%. Water quality parameters during the 45-day rearing period remained stable within the optimal range, with temperatures of 23.1–26.9°C, pH of 7.0–7.2, and dissolved oxygen (DO) of 6.1–6.7 ppm. In conclusion, the use of honey as a natural ingredient is effective in significantly inducing male sex differentiation in guppy fish larvae.

Abstract

This study aims to identify and describe the dynamics of potential fishing areas in Cilamaya Waters, Karawang Regency, using Aqua MODIS satellite imagery data. The method used is quantitative descriptive with a remote sensing approach and spatial analysis. Sea surface temperature and chlorophyll-a data for 2025 were processed using SeaDAS and ArcGIS, then analyzed using an overlay method. Potential areas were identified as areas with sea surface temperatures of 28–32°C and chlorophyll-a concentrations of 0.31–2 mg/m³. The results show that the average sea surface temperature ranges from 28.0–29.4°C, while the average chlorophyll-a ranges from 0.88–1.34 mg/m³. The West Monsoon has the highest average temperature of 29.4°C, while the East Monsoon has the highest chlorophyll-a concentration of 1.34 mg/m³. The overlay results indicate that the location of potential fishing areas changes with each season. The highest catch occurred in the first transition season, at 5.875 kg, or 27.72%, while the lowest was in the eastern season, at 4.533 kg, or 21.38%. This study concludes that Aqua MODIS imagery can be used to describe the environmental suitability and dynamics of potential fishing areas, but does not directly indicate fish abundance.

Abstract

The high fishing activity targeting kawakawa (Euthynnus affinis) at the Kejawanan Fishing Port has the potential to increase pressure on the sustainability of fish resources. This study aimed to analyze the sustainable potential, determine the Maximum Sustainable Yield (MSY) and Total Allowable Catch (TAC), and analyze the exploitation level of kawakawa resources at Kejawanan Fishing Port. The study employed a survey method with a descriptive quantitative approach. Catch and fishing effort data from 2014–2024 were analyzed. The analysis included fishing gear standardization using the Fishing Power Index (FPI), Catch Per Unit Effort (CPUE) calculation, and sustainable potential estimation using the Schaefer and Fox surplus production models. The results showed that cast net had the highest productivity and was therefore selected as the standard fishing gear. The Fox model estimated an MSY of 76.87 tons/year with an optimum fishing effort of 210.97 trips/year. The estimated TAC was 61.50 tons/year, with an allowable fishing effort of 116.67 trips/year. The exploitation level reached 356.81%, indicating that kawakawa resources at Kejawanan Fishing Port were in an overexploited condition. Therefore, fishing effort and catch should be controlled to maintain the sustainability of kawakawa resources at Kejawanan Fishing Port.
