Komposisi Kimia Cacing Kacang (Sipunculus nudus) di Kabupaten Raja Ampat dan Kabupaten Manokwari
Filum Sipuncula adalah biota laut unik, dari penampilan luarnya. Hewan ini mirip dengan cacing, sehingga diistilahkan peanut worm. Masyarakat pesisir Papua khususnya di Papua Barat telah memanfaatkan organisme ini sebagai bahan pangan, tetapi komposisi gizi dari spesies inu belum banyak dibahas. Penelitian dilakukan Maret-April 2014, bertujuan untuk mengetahui komposisi kimia dari Sipuncula nudus yang diambil dari perairan Raja Ampat dan Manokwari. Hasil menunjukkan bahwa kadar air S. nudus dari Kelurahan Sowi 4 Manokwari) yaitu 8.06%, kadar lemak tertinggi terdapat pada Kampung Amdui Raja Ampat) yaitu 1.70%, kadar protein tertinggi berasal dari Kampung Amdui Raja Ampat) yaitu 82.46%, karbo…
Temporal Distribution of Gastropods In Rocky Intertidal Area In North Manokwari, West Papua
Gastropods is an important organism that commonly found inhabiting the rocky intertidal area. Distribution pattern of this species is influenced by various factors such as population history, microhabitat, predation and a complex interactions between oceanographic dynamics and ecological features. This study aims to compare the temporal distribution pattern of gastropods at two different rocky intertidal area. This research was conducted at the rocky intertidal area of Amban and Nuni, North Manokwari District, West Papua. Data collection was performed during the daylight and night in April and June 2012 using systematic sampling method. The results showed that both physical and chemical fac…
Community Structure of Gastropods in Seagrass Meadows at Coastal Area of Nusi and Gersen, Nabire Regency
Gastropods plays an important role in the food chain on seagrass ecosystem and its existence are depend on the physical-chemical factors in the seagrass ecosystem. This study aims to determine the density and diversity of gastropods associated in seagrass habitat in Nusi and Gersen coastal waters. The measurement results of some physical-chemical waters variables, are still quite good for the life of gastropods. Species composition of gastropod in Nusi at higher than at the Gersen, but instead of individual density in Gersen more higher than Nusi. Diversity index of gastropods at Nusi station is higher (3,757) than Gersen (3.053), on the contrary the eveness and dominance index are higher a…
Kelimpahan Makrozoobentos di Daerah Bervegetasi (Lamun) dan Tidak Bervegetasi di Teluk Doreri Manokwari
Makrozoobentos di daerah bervegetasi (lamun) memiliki kepadatan yang lebih tinggi yaitu berkisar antara 0,070-0,085 ind/2738,06 cm3, dibandingkan dengan pada daerah yang tidak bervegetasi yaitu berkisar antara 0,035-0,067 ind/2738,06 cm3. Angka ini juga dibuktikan dengan uji t yang menunjukkan H1 diterima yang berarti ada perbedaan yang nyata antara kepadatan makrozoobentos yang ditemukan di daerah bervegetasi dan daerah tidak bervegetasi. Jumlah spesies yang ditemukan di daearah bervegetasi dengan alat corer di Teluk Doreri adalah 113 spesies dan di daerah tidak bervegetasi ditemukan 57 spesies.
PERTUMBUHAN, UMUR, DAN DIMORFISME SEKSUAL IKAN PELANGI ARFAK, Melanotaenia arfakensis Allen, 1990 DI SISTEM SUNGAI PRAFI, MANOKWARI, PAPUA BARAT
ABSTRACTArfak rainbow fish, Melanotaenia arfakensis is an endemic fish on several river systems in the northeastern part of the Vogelkop peninsula. This study aims to describe the growth, age at first maturity, and sexual dimorphism of this endemic fish on the Nimbai Stream and the Aimasi Stream, the Prafi River system. The fish were caught using handnet, then were measured their standard length and individual weight. Data were analyzed to estimated growth patterns, von Bertalanffy's growth rate, age at first maturity and sexual dimorphism characteristics. The results showed that male growth patterns varied, with a tendency of the increase in body length faster than that of body weight (neg…
