Abstract

Comprehensive information regarding the reproduction, early development, and growth of larvae is very important in the efforts of captive breeding and reintroduction of endangered fish species. One of the species that is starting to be threatened is the Arfak rainbowfish, Melanotaenia arfakensis which is already in the vulnerable category and its information is still relatively limited. Therefore, this study was conducted to describe the spawning activity, early development, and growth of the larvae of this rainbow fish species under laboratory conditions. Experiments on a laboratory scale were carried out in March-September 2017. The fish used came from the Nimbai Stream. A total of three pairs of individual males and females ranging in size from 46.5 to 60.1 mm were selected for treatment. However, only one pair was successfully observed spawning activity completely. Spawning takes place between morning and noon in three spawning periods. In each period, spawning lasts between 8 and 11 days. Between spawning periods takes 14 to 22 days. After fertilization, the eggs are attached with filaments to the spawning substrate and placed at a depth of 7.3-24.3 cm from the surface of the water. One group of eggs spawned consists of 78-116 eggs with a diameter range between 1.05 and 136 mm. The eggs hatch in a period of 4 to 10 days. The body length of the newly hatched larvae ranges from 4.13-4.40 mm and will reach a size of 7.85 mm with a survival rate of 48.1% after 41 days. The results of this study found several advantages from the characteristics of spawning and growth in the early stages that are useful for captive breeding efforts and reintroduction of this rainbowfish to their natural habitat. Thus, its population in the Prafi River system can be maintained.

Abstract

The feasibility study of the location of seaweed cultivation is very important to be carried out in order to ensure the sustainability of the cultivation activities in question. Therefore, this study aims to examine the feasibility of the technical aspects of seaweed cultivation to support the development of seaweed cultivation in the coastal waters of Mengumfoka Village and Kaki Island, Manokwari Regency. The research method is the observation method with survey techniques (in situ and ex situ). The results showed that the two research sites had characteristics of the physical-chemical and biological conditions of the waters that could support seaweed cultivation activities. Location KA1 has a score of 86.2, which means the location is highly suitable, while location KA2 has a score of 75.4 or moderately suitable as a location for seaweed cultivation. In general, KA1 and KA2 locations have the same conditions, but KA2 locations are more open than KA1 locations, so that KA2 locations have more risk due to large currents and waves due to seasons. So the location of KA2 can only do seaweed cultivation during the shady season.

Abstract

The spotted scat, Scatophagus argus (Linnaeus, 1766) is a component of the estuarine ecosystem with little reproductive information. Therefore, this study was conducted with the aim of describing aspects of the reproductive biology of this fish species through sex ratio, size at first sexual maturity, and spawning season. The collection of fish samples from the waters of Pabean Bay was carried out every month between January and December 2015. The fishing gear used were sero and gill nets. A total of 428 individuals were collected consisting of larval, juvenile, pre-adult, and adult stages. The ratio of the number of male and female individuals is relatively balanced (1.00 : 1.05). The size of the male individual's first sexual maturity at a total length of 102.95 mm and 112.44 mm in female individuals. The composition of gonadal maturity level and gonadal maturity index value indicated that there was reproductive activity that lasted throughout the year and increased in January-February and September-November. Information on reproductive aspects obtained in this study can be used as a basis for the management of this fish resource, including through recommendations for closing locations and fishing times.

Abstract

ABSTRACT  Turtles are reptiles that spend most of their lives in marine waters and will return to land to release their eggs at the location where they were hatched. However, changes in land use that cause damage to coastal habitats, catching turtles on land and taking their eggs as well as the threat of predators can cause a decrease in turtle populations. One effort to overcome this is through hatchling breeding activities as was done in Meinyumfoka Village, Manokwari Regency. The objective of the activity is to support community-based conservation through the provision of supporting facilities and community awareness. This activity begins with a site survey, observation and assistance with needs in the captive area, analysis of material needs and costs, organizational activities, and realization of a work plan. This activity was carried out in November-December 2021 in Meinyumfoka Village. The results achieved were the availability of one hatchling hatchery facility measuring 300 cm x 170 cm x 60 cm, three posters for turtle conservation socialization media, and one tourist gazebo. The addition of facilities to the turtle hatchery ecotourism area is expected to bring economic benefits to the surrounding community and also provide benefits for turtle conservation.  Keywords: Facilities; Hatchery; Meinyumfoka; Tourism; Turtle   ABSTRAK Penyu merupakan reptil yang menghabiskan sebagian besar hidupnya di perairan laut dan akan kembali ke daratan untuk melepaskan telur di lokasi dimana pernah ditetaskan. Namun, pergeseran fungsi lahan yang menyebabkan kerusakan habitat pantai, penangkapan penyu di darat dan pengambilan telur serta ancaman predator dapat menyebabkan terjadinya penurunan populasi penyu. Salah satu upaya mengatasi hal ini adalah melalui aktivitas penangkaran tukik sebagaimana yang dilakukan di Kampung Meinyumfoka Kabupaten Manokwari. Tujuan kegiatan yaitu mendukung konservasi penyu berbasis masyarakat melalui penyediaan sarana pendukung dan penyadaran masyarakat. Kegiatan ini dimulai dengan survey lokasi, observasi dan identifikasi kebutuhan di area penangkaran, analisis kebutuhan bahan dan biaya, organisasi kegiatan, dan realisasi rencana kerja. Kegiatan ini dilaksanakan pada bulan November-Desember 2021 di Kampung Meinyumfoka. Hasil yang dicapai yaitu tersedianya fasilitas bak penangkaran tukik berukuran 300 cm x 170 cm x 60 cm berjumlah satu buah, media sosialisasi konservasi penyu berupa poster sebanyak tiga buah, dan pondok wisata/gazebo sebanyak satu buah.  Penambahan fasilitas pada kawasan ekowisata penangkaran penyu ini diharapkan dapat mendatangkan manfaat ekonomi bagi masyarakat sekitar dan juga memberikan manfaat bagi konservasi penyu.

Abstract

Di perairan Indonesia ditemukan tujuh spesies ikan Sidat, yaitu A. marmorata, A. celebesensis, A. borneensis, A. bicolor bicolor, A. bicolor pacifica, A. interioris dan A. nebulosa. Ikan Sidat (Anguilla marmorata) adalah salah satu spesies yang memiliki nilai ekonomis tinggi dan telah menjadi komoditas tujuan eksport. Spesies ini banyak ditemukan di perairan Sungai di Indonesia termaksud di Sungai Prafi Kabupaten Manokwari, Papua Barat. Penelitian ini bertujuan untuk mengidentifikasi ikan Sidat dengan pendekatan morfologi dan genetik serta memahami hubungan genetic spesies A. marmorata. Metode BLAST di NCBI digunakan untuk mengidentifikasi sampel ikan Sidat. 31 Sampel penelitian teridentifikasi sebagai A. marmorata dengan nilai percent identity 100% dan query coverage 99%. A. marmorata yang ditangkap memiliki berat rata-rata sebesar 257.48 gr, panjang rata-rata yaitu 43.19 cm dan jumlah rata-rata ruas tulang ana dorsal sebanyak 18. A. marmorata yang berasal dari manokwari di rekonstruksi dengan dengan beberapa A. marmorata yang berasal dari berbagai negara. Hasil penelitian menunjukkan bahwa, A. marmorata dari manokwari berada pada satu klade yang sama dengan beberapa individu A. marmorata dari China, Brunei, Indonesia-Bali-Jawa Barat, Vietnam, Malaysia, Japang dan French Polynesia. Hal tersebut didukung oleh nilai jarak genetik antar populasi A. marmorata yang rendah yaitu 0%-0,4%. Rekonstruksi pohon filogenetik antar spesies Anguilla sp. menunjukkan bahwa A. marmorata berada pada clade yang sama dengan A. Nebulosa. Hal tersebut didukung oleh nilai jarak genetik yang rendah yaitu 3%. Sedangkan nilai jarak genetik tertinggi yaitu antar A. mossambica dan A. celebesensis (11,4%).

Abstract

The waters of Bintuni Bay have abundant natural resources, especially aquatic biota. One of the aquatic biota with high economic value is the Jerbung shrimp (Penaeus merguiensis). Currently, information about the biological aspects of shrimp in the waters of Bintuni Bay is still very lacking. Specifically, the aim of this research is to examine the size structure, first caught size (L50%), infinity size (L∞), growth patterns, condition factors and gonad maturity level (TKG) of Jerbung shrimp in the waters of Bintuni Bay. The research method used is the survey method. The research was carried out from March to April 2023. The results showed that the average carapace length and weight of male shrimp were 4.6 cm and 14.8 gr. Meanwhile, the average shell length and weight of female shrimp are 5.4 cm and 25.8 grams. The L50% value of male and female shrimp is 5.3 cm and 5.8 cm, the ½ L∞ value of male and female shrimp is 3.4 cm and 3.5 cm. If L50% > ½ L∞ means the size of the shrimp caught is quite large. The growth pattern of male and female shrimp is negative allometry (b = 0.1035 and b = 0.7424). The condition factor values for male and female shrimp are 0.31 and 1.73. The results of TKG observations showed that 75.2% of female shrimp were in TKG I and II, meaning that 50% of the shrimp caught had not yet reached TGK III and IV at the time of the research.

Abstract

ABSTRACT: The waters of Bintuni Bay have potential mangrove crab (Scylla sp.) resources. Mud crabs are aquatic biota that have high economic value. Information about the biological aspects of mangrove crabs in the waters of Bintuni Bay is still very minimal. This research aims to examine the size structure, growth patterns, condition factors and gon-ad maturity level (TKG) of mud crabs in the waters of Bintuni Bay. The research was carried out from May to July 2023. The research results showed that the average carapace width and weight of male mud crabs were 13.6 cm and 553.2 grams. Meanwhile, the average size of the shell width and weight of female mud crabs is 12.5 cm and 284.1 grams. The average size of mangrove crabs caught is included in the catchable category (KKP Ministerial Regulation No. 16 of 2022). The growth pattern of male mud crabs is isometric (b = 3.15), while the growth pattern of female mud crabs is negative allometric (b = 2.12). The condition factor values for male and female mud crabs are 1.01 and 1.03. The results of TKG observations showed that 78.4% of female crabs were in TKG I and II, meaning that 50% of the shrimp caught had not yet reached TGK III and IV at the time of the research.
