Abstract

Walking sharks are endemic to the New Guinea-Australian region, inhabiting shallow reef ecosystems. In Papuan waters there are four species of walking sharks, including Hemiscyllium galei. This research investigated ecological and biological aspects of H. galei in Doreri Bay near Manokwari, West Papua Province. The samples used in this study were collected from two locations in the waters of Doreri Bay, namely the islands of Arowi and Nusmapi between September and November 2020. This research was conducted using underwater visual census (UVC) during nighttime. Observations were made at two locations covering a total area 9,000 m2. A total of 10 individuals (7 males and 3 females) of H. galei were collected during the study. They were identified as distinct individuals based on spot shapes on the pectorals. All of them were then measured their morphometric parameters including total length, precaudal-fin length, head length, and body weight. After measurements were taken, all individual sharks were safely released back into their habitat. Morphometric measurements showed the total length of individual walking sharks obtained was no more than 75 cm for both male and female individuals. The abundance estimates of H. galei at Arowi and Nusmapi were 13,33 ind.ha-1 and 8,88 ind.ha-1 respectively. Analysis of length-weight relationship showed a negative allometric growth pattern, where body length growth was faster than weight gain.  Based on the present study, walking sharks probably occupies only a limited area in Doreri Bay, and are therefore very vulnerable to the daily activities of humans living in the vicinity.

Abstract

Indonesia memiliki berbagai macam sumber daya ikan dan salah satunya adalah ikan tuna sirip kuning. Ikan tuna di Palabuhanratu ditangkap dengan menggunakan pancing tonda dan rawai tuna. Tuna merupakan komoditas ekspor sehingga menyebabkan peningkatan hasil tangkapan dan diperlukan pengelolaan sumber daya ikan yang tepat. Salah satu informasi yang dibutuhkan dalam pengelolaan perikanan adalah hubungan panjang bobot dan faktor kondisi ikan sehingga tujuan dari penelitian ini adalah untuk mengetahui pola pertumbuhan dan factor kondisi ikan tuna sirip kuning yang didaratkan di Pelabuhan Perikanan Nusantara Palabuhanratu Sukabumi. Penelitian dilakukan di Palabuhanratu dari bulan September 2021 sampai Januari 2022. Pengambilan data dilakukan di tempat pendaratan ikan di Pelabuhan Perikanan Nusantara [PPN] Pelabuhanratu. Data yang dikumpulkan pada penelitian ini terdiri dari data primer dan data sekunder. Data primer terdiri dari data panjang dan berat ikan. Panjang ikan (cm) yang diukur adalah panjang total serta Jumlah ikan tuna sirip kuning adalah 200 ekor dengan ukuran ikan yang tertangkap antara 30,9 cm sampai 101, 9. Hasil penelitian menunjukkan bahwa model pertumbuhan ikan tuna sirip kuning diperoleh nilai b sebesar 2.7. Hal ini menunjukkan bahwa ikan tuna sirip kuning mempunyai pola pertumbunan alometrik negative (b<3) dimana pertumbuhan panjangnya lebih cepat dari pada pertumbuhan beratnya sedangkan faktor kondisi ikan Yellowfin Tuna antara 0,70 – 1,54 dengan rata-rata 1,0. Faktor kondisi dipengaruhi oleh ketersedian makanan karena Samusera Hindia tersedia dengan Makanan cukup karena Samudera Hindia terkenal dengan daerah upwelling.

Abstract

Skipjack tuna (Katsuwonus pelamis) has high economic value and opportunities for local and export market demand. The present study aims to investigate growth and exploitation status of the resource. Data collection was carried out in April-August 2021 by collecting catch data from fishermen at four fish landing sites in Manokwari. Skipjack tuna caught from the fishermen were caught in the waters around Manokwari. The size of skipjack tuna measured ranged between 260 mm and 760 mm, with an average monthly size ranging between 540 mm and 595 mm. The relationship between total length and body weight of skipjack tuna followed the equation W = 0.00006L2.7702, where the b value of 2.7702 indicates that the growth pattern of skipjack tuna (K. pelamis) is negative allometric. The growth model using the von Bertalanffy model, found asymptote length (L∞) of 792.75 mm, growth rate (K) of 0.75 year-1 and theoretical age (t0) of -0.0254 years. The total mortality (Z) was 1.32 yr-1. Natural mortality (M) was 0.61 yr-1. The mortality due to capture (F) was 0.71 yr-1. The exploitation rate of 0.54 indicated that the exploitation rate of skipjack tuna in the waters around Manokwari has slightly exceeded the optimum utilization rate. The spawning potential ratio (SPR) value was 16%, which was less than the lower reference point (20%).

Abstract

Environmental and genetic variables can exert an influence on alterations in morphological traits. Within fish species inhabiting diverse aquatic settings, there can be observed variations in morphological traits. Genetically, variations in fish morphological characteristics can occur through mating and gene flow. To date, there has been a lack of research conducted on the variability in morphological traits and genetic relationships between Lutjanus timoriensis, L. malabaricus, and L. erythropterus. Thus, the current research aimed to identify variations in the morphological characteristics as well as in the intra- and inter-specific relationships between three red snapper species from the genus Lutjanus.  Cytochrome oxidase I (COI) gene was used to study the molecular relationship among species of red snapper. The results showed that L. timoriensis had high intraspecific morphological variation in young individuals. Morphologically, L. timoriensis, L. malabaricus, and L. erythropterus are very similar. Unlike L. malabaricus and L. erythropterus, young and adult L. timoriensis have black patches in the pectoral fin axils. The adult L. erythropterus has a comparatively small mouth, no hump on its head, and no black saddle at the base of its tail. Meanwhile, L. malabaricus has a comparatively large mouth, a head with a hump, and a black saddle at the base of its tail. In terms of body size, L. erythropterus is larger than L. timoriensis and L. malabaricus. Based on NCBI and Bold System data, molecular analyses determined that the observed fish were L. timoriensis, L. malabaricus, L. erythropterus with a similarity of between 99.85 and 100%. The phylogenetic tree construction demonstrated that L. malabaricus, L. timoriensis and L. erythropterus were closely related.

Abstract

Penelitian ini mengeksplorasi potensi perikanan sebagai penunjang ketahanan pangan di Provinsi Papua Barat dengan menggunakan analisis Angka Konsumsi Ikan (AKI) dan Angka Kecukupan Protein (AKP). Hasil analisis menunjukkan bahwa distribusi produksi perikanan yang tidak merata berdampak pada asupan protein ikan, terutama di wilayah pedalaman yang tidak berbatasan langsung dengan laut. Meskipun regulasi terkait perikanan telah tersedia, implementasinya masih belum optimal, terutama dalam menjaga kualitas lingkungan dan ekosistem pesisir. Kendala utama meliputi rendahnya kesadaran masyarakat akan kelestarian lingkungan laut serta keterbatasan sarana prasarana, sumber daya manusia, dan finansial. Oleh karena itu, diperlukan peningkatan kesadaran masyarakat dan investasi dalam infrastruktur serta sumber daya manusia untuk mendukung potensi perikanan sebagai penopang ketahanan pangan yang berkelanjutan di Papua Barat.

Abstract

The Lutjanidae family has a wide range of varieties, posing challenges in their morphological identification. Molecular identification is crucial for augmenting the current morphological data as a comprehensive database for documenting the presence of economically significant fish species in Nabire water. This article provides a comprehensive analysis of the morphological and genetic characteristics of red snapper species, as well as assessment of the evolutionary connections among snapper fish found in the water. This study aims to analyze the morphological and genetic characteristics of red snapper species and assess the evolutionary relationships among red snapper found in the sea waters. The DNA extraction procedure was conducted according to the instructions provided by the Geneaid gSYNC DNA extraction kit. The molecular marker used is the DNA barcode of the cytochrome oxidase subunit I (CO1) gene. A total of 29 individuals were identified, representing 8 species, namely Lutjanus timoriensis, Lutjanus gibbus, Lutjanus bohar, Lutjanus papuensis, Pinjalo lewisi, Etelis coruscans, Pristipomoides multidens, and Aphareus rutilans. The molecular analysis indicated that there was a fragment length of 620 base pairs (bp). P. multidens and L.  gibbus had the greatest genetic distance (0.22), whilst the species L. bohar and L. gibbus had the smallest genetic distance (0.11). The phylogenetic tree reconstruction yielded 8 monophyletic clades. Based on morphological and genetic analysis, eight species of the Lutjanidae family were identified in Nabire waters. Research is needed on biological parameters such as size when first caught, optimum length of capture and size when first gonad mature.

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.
