Abstract

ABSTRACTThis research was conducted on 15 June-24 July 2019 in the Unit Pelaksana Teknis Daerah Balai Perikanan Budidaya Air Laut dan Payau (UPTD BPBALP Teluk Buo), West Sumatra. This study aims to determine the effect of stocking density and the best stocking density on growth and survival of Barramundi (Lates calcarifer) seeds. The method used in this study is an experimental method using a non factorial complete randomized design (RAL) with 4 treatments (A: 10 fish/8 liters, B: 20 fish/8 liters, C: 30 fish/8 liters, and D: 40 fish/8 liters) and 3 replications to produce 12 experimental units which were placed randomly. This study used a tub of fiber measuring 2.25 x 1.20 x 5.5 m3 and given a bulkhead using net measuring 20 x 20 x 20 cm3, amounting to 112 units with 4 mm net size and made of polyethylene. The test parameters in this study are absolute weight growth, absolute length increase, specific growth rate, survival rate, and water quality. The results of this study indicate that the best stocking density for growth and survival of Barramundi seeds is 20 fish/8 liters and the lowest is 40 fish/8 liters.Kata kunci: Stocking density, growth, survival, Lates calcarifer.

The research was conducted on February – March 2020 and located in Pandan Island with using survey method. The research aimed to analyze characteristic habitat of the physical and biological turtle nesting beaches, the distribution of turtle’s nests, and the microbial conditions of the turtle’s nests. The result showed that the length of beach was 1,379.4 m with average width of beach was 16.13 m. The average beach slope was 5.52 %. Substrate type dominated by sand substrate. The most abundant vegetation was ketapang tree (Terminalia catappa) and the predators discovered were monitor lizard and dog. There where 4 turtle nests were found, which was 3 nests of hawksbill turtles and 1 nest of green turtle. The average distance of nests from high tide line was 5.7 m with average distance between nest was 177.87 m. Respectively, the average of temperature, humidity, and depth of the nests were 29.58℃, 12.78%, and 53.3 cm.

Abstract

Mudskipper or Periopthalmus variabilis Eggert (subfamily Oxudercinae, Gobiidae) commonly present in the intertidal area of mangrove ecosystem. This fish is able to walk in the forest floor by using its pectoral fins. To understand the gonad development and fecundity of the fish, a study has been conducted in September - October 2014. The fish was sampled by scoop net at night. Results shown that the male-female ratio 2 : 1. The males were in the 1st to 4th maturity levels , while those of the females were in the 3rd, 4th and 5th levels. The fecundity was ranged from 112,496 – 137,698 eggs/fish.

Abstract

Penelitian ini bertujuan untuk mengkaji kondisi ekosistem hutan mangrove berdasarkanKriteria Baku Kerusakan Mangrove dan menyusun strategi pengelolaan ekosistemmangrove di Sungaitohor. Penelitian dilaksanakan pada bulan Februari sampai denganMei 2017 di Desa Sungaitohor. Metode yang dipakai dalam penelitian ini adalah metodesurvey, dimana setiap transek dibentang tali dari laut ke darat. Pada setiap zonasimangrove yang berada di sepanjang garis transek, diletakkan plot pohon berbentukbujur sangkar dengan ukuran 10 × 10 m2 dimana didalamnya terdapat petakan 5×5 m2untuk anakan dan 2×2 m2 untuk semai. Hasil penelitian ditemukan 11 jenis mangrove.Jenis mangrove yang dominan di lokasi penelitian adalah jenis Avicennia alba. Berdasarkankriteria baku kerusakan mangrove, kondisi mangrove dalam kondisi baikdimana kisaran kerapatan pohon adalah 666,67 - 2333,33 pohon/ha, substrat padadaerah hutan mangrove adalah lumpur berpasir. Rata-rata indeks keanekaragaman pohonrendah (H’= 0,74), diakibatkan tingkat abrasi pantai tinggi dan tumbuhan mangroveyang berasosiasi. Strategi konservasi dijelaskan bahwa hutan mangrove di DesaSungaitohor dalam kawasan yang dilarang dalam kepemilikan perseorangan, kawasanmangrove ini tidak diperbolehkan untuk membuka lahan, pemukiman, tambak ikan danpenebangan kayu mangrove secara bebas.

Abstract

This research was conducted in January 2019 in the mangrove area of Purnama Village, Dumai City, Riau Province. The purpose of this study was to determine the crab community structure which includes the type, abundance, crab distribution patterns, species diversity (H '), species uniformity (E), and species dominance (C) crabs. The method used in this study is a survey method. There are three observation stations with each of the three transects at each station, on each transect line there is a square plot with a size of 5x5 m2. Crab sampling is done quantitatively and qualitatively. Based on the results of the study it was found that the species of crabs identified at the area of the research were Sesarma reticulatum, S. guttatum, Uca dussumieri, U. rosea, U. vocans, Cardisoma carnifex, and Clistocoeloma merguinse. Furthermore, the abundance of crabs obtained is between 1560-2040 Ind / Ha with cluster distribution patterns. The average value of species diversity (H ') indicates moderate diversity, uniformity (E) indicates high species uniformity, and species dominance value (C) indicates no dominating species.This research was conducted in January 2019 in the mangrove area of Purnama Village, Dumai City, Riau Province.
