Kotania Bay, West Seram Regency can be clarified as one of the unique bays because it has five smallest islands, which has the important potential coastal ecosystem resources. This bayâ€™s status also has been assigned as a Coastal Conservation Area and Small Islands. These purposes of this research are 1) to know the sub-zone potential cultivation in Kotania Bay, and 2) to analyze and formulate the marine cultivation management strategy in Kotania Bay. The method of data collection used by the researcher are interviews and direct field observations. The data analysis used land suitability index to determine the potential cultivation space (seaweed, sea cucumbers, mangrove crabs and groupers), while the DPSIR is used to produce the marine culture management strategy in Kotania Bay. The potential marine cultivation in Kotania Bay is divided into three sub-zones cultivation with the total area 361,69 ha. The result of the research showed that the suitability of seaweed cultivation land obtained an S1 value of 66% (237.43 ha) and an S2 value of 34% (124.26 ha). The land suitability of the sea cucumber cultivation obtained an S1 value of 94% (340.65 ha) and an S2 value of 6% (21.04 ha). The suitability of cultivated land designated for mangrove crabs, especially the species of Scylla serrata, was obtained very suitable values â€‹â€‹up to 100%. The cultivation activity for grouper fish obtained an S1 value of 93% (338.06 ha), while for an S2 value of 7% (23.63 ha).

The use of the coral ecosystem causes a systemic impact on that ecosystem. There are various types of coral reef ecosystem utilization, and the management of this ecosystem, therefore, needs a collaborative approach. The objective of this study was to identify the condition of coral reef, to identify types of utilization and its impact on the coral reef ecosystem and produce a collaborative management response towards the coral reef ecosystem. The research was conducted n July 2020 at the coral reef area of Biloro Village, Sub-district of Kapala Madang, Southern Buru. Field observation uses the Line Intercept Transect method for coral reef condition assessment, while the PRA approach to identify trigger factors, stress against the environment, the impact, and strategic adaptive response management. The collaborative method is a strategic adaptive response that conveys the system concept of socio-ecology, community capacity, and institutional empowerment in management integration. The result shows that on average coral reef ecosystem was in good condition. There are five responses collaborative management proposed explicitly education advocacy in the importance of coral reef, rehabilitation of degraded coral reef, the establishment of community controlling group, village by law, and the development of Toumahu Island marine tourist. ABSTRAK Pemanfaatan ekosistem terumbu karang memberikan dampak sistematis. Pengelolaan terumbu karang pada lokasi penelitian membutuhkan pendekatan kolaboratif.

The development of awuaculture is significantly influenced by land suitability analysis. This research was conducted from May 2021-April 2022 in Inner Ambon Bay (IAB). This study aims to analyse physical, chemical and environmental factors, suitability and carring capacity of Bubara (Caranx sp) fish farming with Floating net Cages (FNC) system in Inner Ambon Bay. Physical and chemical environmental data were measured in-situ, and the land suitability matrix based on a weighting system was used to analyse the environmental suitability and carring capasity for awuaculture development. The IAB waters have potential for Bubara farming using bery suitable and suitable FNS System. The development of bubara aquaculture with FNC system in IAB waters is in two classes, very suitable to the area range of 1046,30-1113,32 ha and suitable to the area range of 2,25-65,68 ha depending on the season. The carring capacity of the land for placing FNC in the fish farm bubara is about 1.667 units in the west season, about 1.669 units in the transition season I, about 1.670 units in the eastern season and about 1.673 units in the second transition season II. The carring capacity of highly suitable land (waters) is higher (1.568-1.670 units) than that of suitable land (3-98 units). Some of the activities that can reduce the carring capacity of the IAB aquatic environment for fish farming with the FNC are industrial and ship waste disposal, garbage, coastal reclamation, sedimentation, agricultural waste and waste from microorganisms. ABSTRAK Analisis kesesuaian lahan sangat berperan penting dalam pengembangan budidaya perairan. Penelitian ini berlangsung pada bulan Mei 2021-April 2022 yang berlokasi di perairan Teluk Ambon Dalam.

The presence of fish larvae is one of the main factors for the sustainability of fish resources. Information on the potential of fish larvae is very useful for the conservation of fish resources. This study aims to analyze species composition (richness), individual abundance, the relationship of fish larvae abundance with physical-chemical parameters and formulate strategies and priorities for fish larvae management. The research was conducted in August and October at 8 stations. Potential data were analyzed using diversity index, uniformity index, dominance, and abundance of fish larvae. PCA analysis was used to assess the relationship between water quality parameters and fish larvae abundance. SWOT and AHP analysis were used to formulate management strategies and priorities. Based on the results, 9 genus/species of fish larvae belonging to 9 families, 5 orders of Class Osteichtyes were obtained. The abundance of fish larvae was highest in October. Serranus sp. and Siganus sp. larvae had high individual abundance. The parameters salinity, water temperature, current speed, PO4, SiO3, pH, water brightness, and DO have a correlation (+), meaning that these water quality parameters had a directly proportional relationship with fish larvae abundance. Eight strategies were formulated, with two primary priorities for the potential development of fish larvae in Kotania Bay waters, three secondary priorities and three tertiary priorities. ABSTRAK Keberadaan larva ikan merupakan salah satu faktor utama kelestarian sumberdaya ikan. Informasi tentang potensi larva ikan sangat berguna bagi kelestarian sumberdaya ikan. Penelitian ini bertujuan untuk menganalisis komposisi (kekayaan) spesies, kelimpahan individu, hubungan kelimpahan larva ikan dengan parameter fisik-kimia dan merumuskan strategi serta prioritas pengelolaan larva ikan. Penelitian dilakukan pada Agustus dan Oktober di 8 stasiun. Analisa data potensi menggunakan indeks keanekaragaman, indeks keseragaman, dominansi, dan kelimpahan larva ikan. Analisis PCA digunakan untuk mengkaji hubungan parameter kualitas air dengan kelimpahan larva ikan. Analisis SWOT dan AHP digunakan untuk merumuskan strategi dan prioritas pengelolaan. Berdasarkan hasil penelitian diperoleh 9 genus/spesies larva ikan yang termasuk dalam 9 famili, 5 Ordo dari Class Osteichtyes. Kelimpahan larva ikan tertinggi pada bulan Oktober. Larva ikan Serranus sp. dan Siganus sp. memiliki kelimpahan individu tinggi. Parameter salinitas, suhu air, kecepatan arus, PO4, SiO3, pH, kecerahan air, dan DO memiliki korelasi (+), yang berarti parameter kualitas perairan itu memiliki hubungan berbanding lurus dengan kelimpahan larva ikan. Dirumuskan delapan strategi, dengan dua prioritas primer pengembangan potensi larva ikan di perairan Teluk Kotania, tiga prioritas sekunder dan tiga prioritas tersier.
