Abstract

Rastrelliger brachysoma is an important economic fish for coastal communities. Rastrelliger brachysoma included in the red-list of species based on the IUCN of 2017 so the utilization of this species should be taken into account. Excessive and continuous utilization causes this species to dwindle. Fish catches of various sizes and unknown levels of gonad maturity of these fish resulted in female bloating becomes less and feared will be increasingly difficult to find in the water. Research on gonad girth level needs to be done to find out whether the fish catch is indeed feasible to be caught or not capture yet (in this case have experienced mature gonads). The results showed Rastrelliger brachysoma matured gonad on average length of 17.03 cm with sex ratio of 238 ± 20,074 for female fish and the amount of 179 ± 25,408 for male fish. Histologic analysis showed that Rastrelliger brachysoma was at maturity level of gonad I, II, III, IV and V while morphological analysis showed Rastrelliger brachysoma was in maturity level of gonad I, II, III and IV.

Abstract

Dugong merupakan mamalia laut yang termasuk dalam ordo Sirenia, dan tergolong organisme langka yang tercatat dalam IUCN.  Rendahnya populasi dugong disebabkan oleh faktor biologi reproduksinya, perburuan oleh manusia, dan kerusakan habitatnya.  Dugong diketahui memiliki pola makan sebagai herbivora, dan menghabiskan waktu untuk aktivitas makan di padang lamun.  Penelitian terdahulu terhadap isi perut dugong di Indonesia menyebutkan bahwa, 90% perut dugong berisi daun lamun jenis Thalassia hemprichii, Halodule sp., Halophila sp., dan Cymodocea sp., sementara sisanya adalah rumput laut. Tujuan dari penelitian ini adalah untuk mengetahui distribusi padang lamun sebagai habitat pakan dugong, dan ancamannya di Indonesia.  Penelitian ini dilakukan sepanjang Tahun 2012, di 15 pulau kecil wilayah perairan Negara Kesatuan Republik Indonesia (NKRI).  Metode yang digunakan dalam penelitian ini adalah kombinasi transek garis (Line Intercept Transect-LIT) dan transek kuadrat di setiap stasiun ditemukannya padang lamun.   Hasil penelitian menunjukkan bahwa lamun jenis Thalassia hemprichii, Halodule sp., Halophila sp., dan Cymodocea sp. ditemukan di seluruh stasiun pengamatan.  Keempat jenis lamun tersebut ditemukan membentuk padang lamun monospesies maupun heterospesies, dengan kondisi kualitas perairan yang relatif baik untuk tumbuh dan berkembang biak.  Padang lamun sebagai habitat pakan dugong yang ditemukan  selama penelitian di 15 pulau kecil diketahui memiliki ancaman lingkungan beragam, antara lain proses sedimentasi dan konversi lahan oleh manusia.

Abstract

 Taman Kili-Kili Beach is designated as an Essential Ecosystem Area (KEE). 188/39/KPTS/013/2020. According to the Supervisory Community Group (Pokmaswas), in 2011-2020, there was an increase in broodstock as many as 52 turtles, and the eggs saved as many as 3323 eggs. However, since 2013 Pokmaswas data shows a decrease in the population of hawksbill and green turtles in turtle conservation areas, which is thought to be caused by climate change, global warming, and animals. This study aims to analyze environmental baselines, turtle populations, and the value of turtle ecotourism (ecological, economic values) and develop strategies to support turtle conservation at Taman Kili-Kili Beach Trenggalek Regency. The results of the adjustment of nesting habitats and turtle ecotourism, calculation of the Habitat Conformity Index (IKH) of turtle nesting, IKH = 77.77%, which belongs to the category (S1) is very suitable to be used as a conservation area and turtle nesting habitat. While the results of the calculation of the Turtle Ecotourism Conformity Index (IKW), IKW = 84.93%, which is included in the (S1) category, which is very suitable for use a turtle tourism area. The strategy for developing turtle ecotourism is in quadrant II, meaning that it utilizes the strengths possessed in the turtle conservation area by minimizing the threats that it will experience.
