Abstract

There are several option management measures in preventing sustainability stock of the blue swimming crab (Portunus pelagicus), i.e., nursery ground conservation. Thus, the objective of this study was to analyses habitat characteristic and its population biology in the PGN marine embayment of Labuhan Maringgai, as one among crab habitat essential in East Lampung coastal water. The potential nursery ground conservation was assessed by habitat suitability index, carrying capacity, distribution and abundance as well as crabs size. The result shows that environmental condition was still suitable, even though the habitat carrying capacity tend to degraded by an increasing of turbidity and sedimentation at the embayment mouth. The crabs captured were also not representing of peak abundance season and recruitment during sampling period, while those crab size almost 100% under Lm50. The strategic management directive is required to control in utilization of crab’s essential habitat, including crab fishing by any fishing gear resulted undersize captured crabs. Meanwhile, to propose habitat essential conservation might need more consideration and comprehensive study, including social economic and cultural aspects and co-management approach may be required in management measure applied.

Abstract

Information abundance and distribution of fish larvae in coastal waters of East Lampung currently very limited. The research aimed to improve the knowledge of the early life of organisms, in order to manag biodiversity and biological resources in the waters. Research station representing the several water sectors: in-shore, near-shore, and off-shore. The research was a representation of eastern monsoon (June) and transition monsoon (September) in 2017. Fish larvae was harvested using bonggo-net tool while its identification to family level using portable Dino-lite. Based on the result the Abundance of fish larvae in eastern monsoon was higher than transition monsoon. This research found 81 families of fish larvae. There were 10 dominant families, that are Gobiidae, Pegasidae, Mullidae, Pomacentridae, Sillaginiidae, Bleniidae, Bythitidae, Carangidae, Pseudochromidae and Bothidae. The distribution of fish larvae in the lower in-shore was higher than near-shore and off-shore, while east and transitional seasons have not much different larval catches.  Temperature, salinity and pH parameters indicated optimal range state for survival and growth of fish larvae, brightness and turbidity in accordance with water quality standards, currents velocity on eastern monsoon is very fast while transition monsoon is fast to very fast. Phytoplankton and zooplankton showed sufficient natural food availability for the life of fish larvae. Result Canonnical Corespondence Analysis (CCA) analysis to connectivity of abundance and larvae distribution showed that the brightness parameter forming a point projection while other water environment condition parameters form a vector projection in both period of monsoon. The abundance and fish larvae distribution in coastal waters of East Lampung in all three sectors of the waters had proportionality to the parameters of environmental conditions, especially the current parameters and the difference of the monsoon period.

Abstract

Prioritas perencanaan sangat penting ditentukan untuk menjadi acuan pengelola dalam meningkatkan efektivitas pengelolaan kawasan konservasi perairan. Penelitian ini bertujuan untuk menganalisis prioritas perencanaan pengelolaan kawasan konservasi perairan daerah (KKPD) Pulau Ay-Rhun menggunakan metode Jejaring Analitik (Analytic Network Process, ANP). Permasalahan dan solusi dalam penentuan prioritas pengelolaan ini dikelompokkan menjadi empat, yakni: cluster ekologi, ekonomi, sosial, dan kelembagaan dengan masing-masing sub-cluster berdasarkan hasil diskusi kelompok terfokus (Focus Group Discussion, FGD). Hasil analisis menunjukan bahwa masalah utama kawasan konservasi perairan Pulau Ay-Rhun adalah cluster ekologi. Sementara hasil analisis sub-cluster menunjukan bahwa permasalahan prioritas pengelolaan adalah: (1) cluster kelembagaan berupa kurangnya kapasitas dan kuantitas SDM dengan nilai 0,6711; (2) cluster sosial berupa kurangnya pemahaman terkait konservasi dengan nilai 0,6340; (3) cluster ekonomi berupa ketidakstabilan harga jual hasil perikanan dengan nilai 0,5684; (4) cluster ekologi berupa penambangan pasir dan karang untuk material bangunan dengan nilai 0,4614. Mengingat sub-cluster suatu cluster dapat mempengaruhi elemen lain dalam cluster yang sama dan dapat pula mempengaruhi elemen pada cluster yang berbeda, maka rekomendasi prioritas strategi pengelolaan dalam meningkatkan efektifitas kawasan konservasi perairan Ay-Rhun adalah: (1) cluster ekonomi berupa optimalisasi pemanfaatan sesuai daya dukung dengan nilai 0,6137; (2) cluster ekologi berupa pembentukan zonasi dengan nilai 0,5484; (3) cluster kelembagaan berupa penyusunan kebijakan pengelolaan dengan nilai 0,5308; dan (4) cluster sosial berupa sosialisasi mengenai konservasi dengan nilai 0,4680.

Abstract

Information on habitat preferences of the blue swimming crab (BSC) juvenile and its spatial distribution is one of the factors behind the successfulness of its sustainable management. This information is needed to provide input for management strategy by considering juvenile crabs and their habitat as important aspect. The purpose of this study is to elucidate habitat preferences, abundance and biomass distribution of BSC juvenile in the east Lampung coastal waters. The research was conducted in September-October 2018, which was located in east Lampung coastal waters, Province Lampung. Spatial distribution through estimation of abundance and biomass of BSC juvenile were relatively high and concentrated in the Gambas and Wako regions at stratification of 2-4 miles from the coastline. The BSC juvenile does not appear to have a high preference to the Kuala Penet coastal habitat condition; it is considered because of low value of abundance, biomass, and Habitat suitability index (HSI). The value of HSI in the Kuala Penet Coastal region is also lower than other locations due to abiotic and biotic factors for supporting the crabs at juvenile stage.

Abstract

Horseshoe crabs are living fossils found in Indonesia. This study examined the food habit of horseshoe crabs (Carcinoscorpius rotundicauda and Tachypleus gigas) collected from Balikpapan coastal waters, East Kalimantan. Horseshoe crabs were captured using gill nets and picked by hand along the Balikpapan coast. The width of the prosoma and the body weight of each individual were measured, and the gut contents were analysed to determine the preponderance index, food niche breadth, and niche overlap. Carcinoscorpius rotundicauda prosoma widths ranged from 4.1 to 15.4 cm and those of Tachypleus gigas ranged from 2.8 to 24 cm. Eight food items were found in the gut of the horseshoe crabs, namely: bivalves, gastropods, scaphopoda, polychaetes, echinoderms, crustaceans, leaf litter and others. Based on the preponderance index, gastropods were the main food item of the two horseshoe crab species. In accordance to the food composition the horseshoe crabs inhabiting Balikpapan coastal waters are categorized as benthivores.

Abstract

Tingkat pemanfaatan sumber daya rajungan tahun 2016 di Wilayah Pengelolaan Perikanan (WPP-NRI) 712 mencapai over-optimum. Kajian mengenai stok diperlukan dalam pengelolaan perikanan berkelanjutan guna mempertahankan ketersediaannya. Tujuan penelitian ini adalah mengidentifikasi stok rajungan berdasarkan karakter morfometrik (truss network analysis) di WPP 712. Pengambilan contoh rajungan dilaksanakan di lima lokasi yang berbeda, yaitu Lampung Timur, Pulau Lancang, Cirebon, Rembang, dan Selatan Madura. Pengukuran karapas rajungan dengan TNA dilakukan pada 14 titik landmark dengan 29 karakter untuk menganalisis karakter morfometriknya. Analisis kluster menunjukkan bahwa terdapat dua unit stok rajungan di WPP 712. Stok pertama adalah populasi rajungan Selatan Madura, dan stok kedua merupakan rajungan dari empat populasi lainnya. Jarak Euclidean terpanjang ditemukan di Madura Selatan yang menunjukkan rendahnya tingkat kesamaan dengan populasi lain. Analisis diskriminan menunjukkan hasil yang berbeda. Ada tiga populasi kelompok, yang setiap populasi dalam satu kelompok mampu mewakili populasi lainnya, yaitu Pulau Lancang-Cirebon, Lampung Timur-Rembang, dan Madura Selatan. Berdasarkan penelitian ini, maka direkomendasikan untuk mengelola rajungan di Madura Selatan secara terpisah dengan membentuk sub manajemen area di WPP 712.
