OPTIMIZING THE SUBSTITUTION LEVEL OF Lemna perpusilla IN COMMERCIAL FEED TO ENHANCE GROWTH AND FEED EFFICIENCY OF COMMON CARP (Cyprinus carpio) FINGERLINGS
Get PDFFeed production costs constitute the largest expense incurred by fish farmers. Common carp (Cyprinus carpio) is highly favored by consumers due to its delicious taste and affordable price. Rearing common carp fingerlings requires high costs, particularly for feed provision. Feed supplements are needed to enhance feed quality, digestibility, and growth efficiency to reduce feed expenses. One potential feed ingredient derived from aquatic plants that can be used as a supplementary feed is Lemna perpusilla, which has high protein content and effectively improves feed quality for several freshwater fish species. This study used common carp fingerlings measuring 3–5 cm and was conducted from June to July 2023 at UPR Amphibi Batang Toru. A Completely Randomized Design (CRD) was applied with five treatments and three replications, using Lemna perpusilla supplementation at 0% (control), 10%, 20%, 30%, and 40%. The final results concluded that the most optimal and efficient Lemna perpusilla supplementation in feed was 40%, which significantly influenced the growth of common carp
SUBSTITUTION OF FLOUR SEA GRAPES Caulerpa racemosa FERMENTED ON TILAPIA (Oreochromis niloticus) FEED
No full textThe purpose of this study was to analyze the effect of substitution of C. racemosa fermented sea grape flour in the feed formulation on tilapia. This research was conducted at the Laboratory of Fish Production and Reproduction, University of Mataram for 50 days from March-May 2022. This study used an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatments tested were control (P1), 4% fermented sea grape flour (P2), 8% fermented sea grape flour (P3), and 12% fermented sea grape flour (P4). Data were analyzed using analysis of variance (ANOVA) at 5% level with 95% confidence interval and continued with Duncan's test. The results showed that the average absolute weight of fish for 50 days of rearing mass with artificial feeding and at various concentrations of fermented C. racemosa sea grape flour ranged from 9.43-11.58 g, absolute length ranged from 2.24-2 .90 cm, and the specific growth rate ranged from 2.36 to 2.64%/day. Then for the efficiency of feed utilization (EPP ranges from 76.8-95.8%, feed conversion ratio (FCR) ranges from 1.05-1.31 and survival (SR) ranges from 90-97%. Conclusions from this study that the addition of the concentration of fermented C. racemosa sea grape flour can affect the absolute weight of tilapia, but does not affect the absolute length, specific growth rate, FCR value, feed efficiency, and survival rate. 4% (P2) gave the best result because it could increase the absolute weight of tilapia by 11.58

Komposisi dan Ukuran Ikan Hasil Tangkapan Pukat Cincin di Pangkalan Pendaratan Ikan Pontap, Palopo, Sulawesi Selatan
Get PDFPengoperasian pukat cincin oleh nelayan di Pangkalan Pendaratan Ikan (PPI) Pontap menimbulkan persaingan yang sangat tinggi dalam kegiatan penangkapan ikan. Persaingan ini tentunya dapat memunculkan kekhawatiran terjadinya penangkapan ikan berlebihan (overfishing) tanpa memperhatikan kelayakan ukuran ikan hasil tangkapan. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengetahui komposisi dan kesesuaian ukuran ikan hasil tangkapan kapal pukat cincin di PPI Pontap. Penelitian dilaksanakan di PPI Pontap dari tanggal 13 Agustus – 12 Oktober 2024. Metode penelitian yang digunakan yaitu observasional dan analisis datanya secara deskriptif. Hasil penelitian menunjukkan komposisi hasil tangkapan pukat cincin di PPI Pontap ada 6 jenis ikan yaitu kembung perempuan 9.252 kg (25,47%), kembung lelaki 2.034 kg (5,60%), tembang 3.060 kg (8,42%), layang 19.980 kg (55%), cakalang 1.080 (2,97%) dan selar tetengkek 920 kg (2,53%). Berdasarkan ukuran panjang tubuh ikan pertama kali matang gonad, maka ikan kembung lelaki, ikan kembung perempuan dan ikan layang layak tangkap sedangkan ikan cakalang, ikan selar tetengkek dan ikan tembang tidak layak tangkap.The operation of purse seine by fishermen at the Pontap Fish Landing Base creates very high competition in fishing activities. This competition can certainly raise concerns about overfishing without considering the appropriateness of the size of the fish caught. Therefore, this study aimed to determine the composition and suitability of the size of the fish caught on purse-seine vessels at the Pontap Fish Landing Base. The study was conducted at the Pontap Fish Landing Base from August 13 to October 12, 2024. The research method used was observational, and the data analysis was descriptive. The results of the study showed that the composition of the purse seine catch at the Pontap Fish Landing Base consisted of 6 species of fish, namely shortbodied mackerel 9,252 kg (25.47%), indian mackerel 2,034 kg (5.60%), sardine 3,060 kg (8.42%), mackerel scad 19,980 kg (55%), skipjack tuna 1,080 (2.97%) and torpedo scad 920 kg (2.53%). Based on the length of the fish’s body when the gonads first mature, shortbodied mackerel, indian mackerel, and mackerel scad are suitable for catching. In contrast, skipjack tuna, sardine, and torpedo scad are not suitable for catching
Efektivitas Dan Kesesuaian Alat Tangkap Ikan Pacing Tonda Terhadap Permen Kp No.18 Tahun 2021 Di Natuna, Kepulauan Riau
Get PDFStudi ini mengkaji tentang penggunaan alat tangkap pancing tonda oleh nelayan di Natuna, Kepulauan Riau. Penelitian dilaksanakan berdasarkan Peraturan Menteri Kelautan dan Perikanan (PERMEN KP) No.18 Tahun 2021 yang mengatur tentang penangkapan ikan. Tujuan dari penelitian ini adalah untuk mengevaluasi kesesuaian operasi pancing tonda terhadap peraturan pemerintah dan efektivitas teknisnya dalam mendukung keberlanjutan sumber daya ikan. Metode penelitian dilaksanakan menggunakan identifikasi lapangan, uji operasional di laut, dan pengumpulan data sosial ekonomi. Hasil penelitian menunjukkan bahwa penggunaan pancing tonda di Natuna tidak sesuai dengan peraturan pemerintah, terutama mengenai jalur penangkapan dan kapasitas alat tangkap. Data lapangan menunjukkan penggunaan pancing nelayan adalah 15 hingga 25 pancing per main line, dimana jumlah ini melebihi batas dari 10 pancing yang ditetapkan oleh undang-undang. Studi ini juga menemukan bahwa cara nelayan menggunakan pancing tonda dan ulur secara bergantian berperan penting dalam meningkatkan efisiensi. Berdasarkan pengkajian di lapangan, diperlukan adanya peninjauan ulang terkait dengan regulasi pemerintah untuk mendukung operasional nelayan kecil, termasuk pembukaan jalur III untuk alat tangkap tonda, guna memperkuat pengelolaan wilayah laut perbatasan secara berkelanjuta
ANALYSIS OF FACTORS AFFECTING THE SELLING PRICE OF FROZEN BIG EYE TUNA (TUNNUS OBESUS) AT CILACAP FISHING PORT
Get PDFBigeye tuna is one of Indonesia's leading fishery commodities. One of the main locations for the routine landing and handling of this species is the Cilacap Fishing Port. The selling price of bigeye tuna plays a crucial role in the sustainability of fisheries businesses. However, unstable and unpredictable tuna prices make it difficult for some businesses to assess their long-term sustainability. Various factors influence tuna prices, both internal to fishing operations and external economic conditions. This study aims to identify factors that influence the selling price of bigeye tuna at the Cilacap Fishing Port. This study used direct observation, interviews, and a literature review, with data ranging from 2022 to 2024. The analytical approach used was multiple linear regression analysis. The research findings indicate that the selling price of frozen bigeye tuna is influenced by production volume, production value, fishing month, and operational costs. The F-test results indicate that the dollar exchange rate, export volume and value, production volume, production value, fishing month, and operational costs simultaneously influence the selling price of bigeye tuna. These variables influence 80.6% of the selling price of bigeye tuna, while 19.4% is influenced by other factors outside the research.
