Budi daya ikan Kerapu Bebek Cromileptes altivelis mempunyai peluang yang baik pada masa yang akan datang, meskipun masih mengalami kendala dalam pemeliharaannya. Salah satu parameter yang perlu diperhatikan adalah padat tebar yang berhubungan dengan luas wadah pemeliharaan. Tujuan penelitian ini adalah untuk mengetahui jumlah padat tebar yang sesuai untuk menghasilkan pertumbuhan optimum ikan Kerapu Bebek C. altivelis yang dipelihara dalam keramba jaring apung. Penelitian dilakukan menggunakan metode eksperimen dengan 3 perlakuan padat tebar dan 3 ulangan. Keramba yang digunakan berukuran 1 x 1 x 1,5 m3 sebanyak 9 buah dengan ukuran mata jaring 0,5 inci. Penelitian dilakukan di perairan Banda Neira, Maluku, dengan kondisi perairan selama percobaan adalah salinitas berkisar 33,2â34,6â°, suhu perairan berkisar 25â31Â°C, pH berkisar 7â7.5, kecepatan arus berkisar 0,32â3.97cm/s, kejernihan air berkisar 14,29â20 m. Pakan yang diberikan adalah ikan rucah dengan frekuensi pemberian pakan dua kali sehari, yaitu pada pagi dan sore hari sebanyak 10% dari berat total tubuh ikan. Hasil penelitian menunjukkan setelah 4 bulan dibudidayakan pertumbuhan mutlak yang terbaik ditunjukkan oleh perlakuan padat tebar 25 ekor, yaitu 18,22 g, sedangkan terendah ditunjukkan oleh perlakuan padat tebar 75 ekor, yaitu 13,25 g. Laju pertumbuhan spesifik pada perlakuan padat tebar 25 ekor mencapai 1,34%/hari, perlakuan padat tebar 50 ekor mencapai 1,18%/hari, dan perlakuan padat tebar 75 ekor mencapai 0,97%/hari.

This research was conducted in the waters ofÂ Muara Gembong, Bekasi, on Â January to March, 2018. Sampling of blood cockle is carried out in 3 station vertically to the direction of the sea. Determination of station is carried out based onÂ the fishing ground of the fisherman. Analyses of blood cockle is carried out in the Laboratory of the Research Center for Oceanography, LIPI, Ancol â North Jakarta. This research was aimed to analyze the reproductive biological aspectsÂ which includes the ratio of gender, the gonad maturity rate, the gonad maturity index, the length-weight relationship, the condition factor of Anadara granosa in the waters of Muara Gembong, Bekasi. The results of observation of 400 samples showed that the length-weight relationship of blood cockle ofÂ female andÂ maleÂ has the pattern of the negativeÂ allometric relationship. The overall ratio of gender between the blood cockle of male and female is 1.3:1. The average value of the gonad maturity index of the male blood cockle is 1.1874 and theÂ value of the gonad maturity index of the female blood cockle is 1.1983.Â Key words: Anadara granosa, growth, the ratio of gender, gonad maturity index

SPATIAL VARIATION IN POPULATION CHARACTERISTICS OF VENUS CLAM GAFRARIUM TUMIDUM RÃDING, 1798 (BIVALVIA: VENERIDAE) IN AMBON BAY, MALUKU Islami, Muhammad Masrur; Bengen, Dietriech Geoffrey; Dody, Safar

Ambon Bay consists of two regions i.e. Inner and Outer Ambon Bay that was separated by Galala-Poka sill. Consequently these waters have different local environmental conditions that leads to the bivalve populations differences, one of them is venus clam Gafrarium tumidum. In this study, the distribution and spatial variation in population characteristics of of venus clam was quantified based on the analysis of their twelve shell dimensions from different populations. Fieldwork and analyses were conducted on April â Juni 2013. Total of 585 individuals of venus clam were found and could be divided into ten size-classes and three size categories i.e. small (< 23.11 mm), medium (23.12â32.05 mm) and large size (> 32.06 mm). The highest size-class density was found at medium size. Spatial distribution was related to the characteristics of sediment and other potential factors. Result of discriminant analysis showed that shell-width (SW) was the variable with the highest discriminating power and distinguishing between Inner and Outer Ambon Bay populations.

Dog conch (Strombus turturella) is considered one of fishery commodities in Bangka Belitung Islands. This conch is often exploited and result in their populations are increasingly threatened. The aim of study to observe the reproduction and larval development of dog conch were studied under laboratory conditions. For the treatment of spawning the dog conch were placed in spawning tanks with a capacity of 1 ton. Stimulation of spawning is done by replacing the water in the tank as much as 90% every 24 hours until the eggs released by females. Spawning was preceded by copulation and fertilization occurs inside the female's body.The results showed that the first egg cell divides into two cells after two hours of spawning. Then each cell continues to divide into four cells to become multicellular and reach the gastrula stage after 48 hours. Free swimming larval phase for four days and then settle down along with the formation of the first shell. The larvae will grow up to 5 mm shell length for 20 days.Keywords: Dog conch, Strombus turturella, spawning, larva development

Tujuan penelitian ini adalah untuk mengetahui status struktur komunitas gastropoda pada ekosistem terumbu karang di Pulau Tidung, Kepulauan Seribu. Pengamatan dilakukan pada 2 lokasi terumbu karang berdasarkan kondisi (life form) “rusak” (Stasiun 1: life form 0-24.9 %) dan kondisi “sedang” (Stasiun 2: life form + 36.05%). Pengamatan dilakukan pada daerah terumbu karang menggunakan metode LIT (Line Intercept Transect) sepanjang 50 m serta pengambilan sampel Gastropoda menggunakan metode transek kuadrat (1 x 1 m) pada kedalaman 90 cm. Garis transek (LIT) 50 m diletakan sejajar dengan garis pantai dengan jarak tiap garis transek adalah 25 m dengan 3 ulangan. Hasil pengamatan menunjukkan bahwa Gastropoda berasosiasi dengan terumbu karang, karena menggunakan terumbu karang sebagai habitat, tempat berlindung atau memakan jaringan/lendir karang. Jenis-jens yang ditemukan adalah Lambis lambis, Drupella sp., Cypraea tigris, Filifusus filamentosus, Cerithium asper, and Angaria nodosa. Kepadatan Gastropoda adalah 4-7 indv/m2 (Satasiun 1 > stasiun 2). Keragaman Gastropoda tergolong sedang (4.16 - 36.05%), dan nilai Dominasi (D = 0,69) oleh jenis Drupella sp.

The zooplankton ecological index which includes diversity, uniformity and dominance is one approach used to determine the condition of the aquatic environment. This study aims to determine the environmental status of the waters based on zooplankton ecological index which includes diversity, uniformity, and dominance in Doreri Bay water, Manokwari. This study was conducted in September 2020 at two 5- and 10-meter stations depth from the water's surface. Water quality measurements and water sampling were carried out at both stations thrice for 1 week. Water sampling to determine individual zooplankton used a 5 L volume Van Dorn. Temperature, salinity, and pH of the waters were measured successively using a rod-type thermometer with a 50 °C scale, a handheld refractometer RHSN-10ATC, and a pH meter of Orion A215 type. The measurement results obtained the temperature, salinity, and pH values ranging from 29.1 – 29.9 °C with an average of 29.5 °C, 30 – 35 ppt with an average of 33.2 ppt, and 7.9 – 8.3 with an average of 8.1, respectively. The diversity, uniformity, and dominance indexes ranged from 1.5 – 2.2, 0.7 – 1.0, and 0.1 – 0.4, respectively. The ecological status of Doreri Bay waters based on the diversity, uniformity, and dominance indexes show that the components of the food chain are still complete, including the producer and consumer groups and reducers. The effect of liquid waste from land activities around the bay has not disturbed the zooplankton.
