Abstract

Sidat merupakan ikan katadromus yaitu ikan yang memiliki fase dewasa berada di sungai atau danau tetapi setelah matang gonad akan beruaya ke laut lepas dan memijah disana. Perjalanan yang jauh dan membutuhkan waktu yang lama dengan berbagai rintangan. Sidat memiliki gizi yang tinggi yang kaya akan permintaan akan ekspor. Permintaan yang tinggi juga berdasal dari budidaya pembesaran sidat yang meningkatkan penangkapan sidat akan benih dari alam. Tujuan penelitian ini adalah memberikan gambaran karateristik biologi dan penangkapan ikan sidat di beberapa sungai di Kota Bengkulu. Karateristik yang dimaksud adalah distribusi panjang, hubungan panjang berat, nisbah kelamin, gambaran gonad ikan sidat, indeks kematangan gonad dan indeks hati. Hasil penelitian menunjukan distribusi panjang ikan sidat terbesar berasal dari Sungai Muara Jenggalu dan yang terkecil dari Sungai Hitam. Pola pertumbuhan berbeda tiap lokasi sungai yaitu allometrik negatif untuk ikan yang berasal dari Sungai Hitam dan Muara Bangkahulu. Pola pertumbuhan isometrik didapatkan dari lokasi Muara Jenggalu. Nisbah kelamin yang ada didominasi oleh ikan yang intersex. Indeks kematangan gonad dan indeks hati menunjukan trend kenaikan berat hati mengikuti tren pertumbuhan panjang.

Abstract

This study aimed to determine the presence of AMD, analyze mangrove structure, and determine the relationship between AMD and mangrove density. AMD and mangrove stands were collected using a 40 meter transect line parallel to the shoreline, and four 10 x 10 m plots were created. One-way ANOVA statistics were used to test the mean differences in SLA telling, while the Shapiro-Wilk test and Spearman correlation were performed to analyze the relationship between SLA telling and mangrove structure. A total of 11923 AMD items were found in the Cut Mamplam mangrove ecosystem, with a density ranging from 47075 to 76900 items/ha. Furthermore, four species of mangrove trees were found in the mangrove stands, with Avicennia alba having the highest tree, sapling, and seedling densities (3275 ± 5158 ind/ha, 2800 ± 1932.18 ind/ha, and 132500 ± 75883.68 ind/ha). The relationship between AMD and mangrove density was not very strong, with no significant associations between adults, saplings, or seedlings (p > 0.05) on the amount of AMD retained in the Cut Mamplam mangrove ecosystem. This study is an initial step in assessing the impact of AMD on mangrove vegetation and sustainable monitoring, leading to the initiation of public awareness and future strategies for improved coastal and marine monitoring and management.

Abstract

Priacanthus tayenus fish, often referred to as Swanggi, were found during fishing activities in the Cituis area, Banten. This indicates that the potential population of this fish remains substantial and has high economic value. A total of 30 fish were obtained, consisting of 11 female fish and 19 male fish. This study used the purposive sampling method. Analysis of the relationship between the length and weight of Swanggi fish from the waters of Cituis showed a correlation coefficient (r) of 0.9305. This figure indicates that the growth of the Swanggi fish is isometric. The length of the Swanggi fish (PB) increases with increasing morphological size. Food availability is thought to influence these correlation results. The availability of food plays a crucial role in the growth process. These correlation results indicate that food availability in the waters is still sufficient to support the life of the Swanggi fish.
