Pengambilan sampel meroplankton kepiting dilakukan pada empat titik yang ditentukan berdasarkan sungai yang terdapat di kawasan mangrove dengan cara menjaring air sebanyak 150 liter menggunakan plankton net. Dari hasil penelitian di dapatkan bahwa meroplankton kepiting yang banyak di temukan zoea dan mengalapa. Secara umum, kondisi kelimpahan meroplankton kepiting di perairan sekeliling mangrove di dapatkan lebih melimpah pada saat malam hari daripada pagi. Kelimpahan tertinggi pada saat pagi hari di dapatkan pada titik sampling I dan II sebanyak 11 ind/150 l, sedangkan pada malam hari di temukan pada titik sampling I sebanyak 60 ind/150 l. Kondisi kualitas air di perairan sekitar penelitian di dapatkan suhu 27,9-30 o C, salinitas sebesar 22-29 ppt, pH berkisar 6,8-8,1 dan oksigen terlarut 3,12-5,33 ppm.

The water quality have important rules in this waters as indicator type of waters. Considering that condition a study of water quality condition was very importance. This study was studied from Mei until December 2009. Sampel waters collected at intertidal area with survey method and stratified systematic sampling. In each location divided based on 2 station area every take the sample. From physical parameters condition were founded that transparency about 170 cm until 215 cm, temperature 30 until 31 o C and speed of current about 0.31 m/s-0,61 m/s. Type of tidal in juata waters is Mixed Tide Prevailing Semi Diurnal. Chemical parameters water condition were founded that salinity is about 18.8 until 24.3 promil, pH obout 7.82-8.02, Dissolved oxygen (DO) obout 5.

Organisme ini berkontribusi besar terhadap detritus organik yang sangat penting sebagai sumber makanan bagi biota yang hidup diperairan sekitarnya. Tujuan dari penelitian ini untuk mengetahui struktur komunitas gastropoda dari variabel kelimpahan, indeks keanekaragaman, indeks dominansi, dan indeks keseragaman di Kawasan Konservasi Mangrove dan Bekantan (KKMB). Metode yang digunakan dalam penelitian ini adalah metode dekskriptif dengan teknik survei dengan menentukan stasiun penelitian berdasarakan kondisi mangrovenya. Penelitian yang telah dilakukan ditemukan 25 spesies gastropoda yang berasosiasi di hutan mangrove KKMB Kota Tarakan.

One of fauna found which fouded is nomei fish (Harpodon nehereus). That has economic value so that faced high exploited at two season in one month. The plankton have important rules in this waters as food primer for first organisms. Considering that condition a study of distribution and their population structure was very important. Population structure and distribution of plankton in the Juata Waters, Tarakan city, East Kalimantan, were studied from Mei until December 2009. Plankton collected at intertidal area with survey method and stratified systematic sampling. In each location divided based on 2 station area every take the sample. Plankton at Juata Waters is very variate, its were founded 32 specieses include 20 specieses phytoplankton and 12 specieses zooplankton.The distribution, and mean density of the plankton were difference at each station.

The group category of crabs that found in trading Tarakan City have many variation name, They are H7, H5, H3, TG, CBH, CBK, % dan BS. PENDAHULUAN Sumberdaya perikanan Indonesia yang diekspor keluar negeri cukup beragam, salah satunya yang memiliki permintaan tinggi adalah kepiting bakau (Scylla sp). Kepiting bakau (Scylla sp.) adalah salah satu organisme golongan crustacea yang hidup di habitat di hutan mangrove/bakau. Kepiting bakau (Scylla sp.) merupakan komoditas ekspor bernilai ekonomis tinggi dari Indonesia salah satunya yang berasal dari perairan Provinsi Kalimantan Utara. Menurut Gunarto & Cholik (1989) dalam Suman (2002) kepiting bakau merupakan salah komoditas perikanan yang patut dikembangkan karena semakin meningkatnya harga dan...

Condition of in this stage is very important for crabs abundance in the mangrove ecosystem. This study aims to determine the abundance crabs meroplankton and water quality conditions west part in the waters surrounding the Mangrove Conservation Area and Bekantan (KKMB), Beringin, SDF Harbour, and Mamburungan Estuary during high tide occurs. Sampling of crab meroplankton conducted at four using plankton net. The result showed that the crabs meroplankton are commonly found in zoea and megalopa stage. Generally, condition of crab meroplankton abundance in the part western of the Tarakan city obtained more abundant during in the evening than the afternoon. The highest abundance during the affternoon get at Estuary Mamburungan about 7 ind, while in the evening found at KKMB about 108 ind. Water quality conditions in the waters research found that salinity in the afternoon 23 to 33 g/l, pH 6.6 to 7.2, temperat...
