Abstract

Mud crab is one of the 12 aquaculture commodities of Ministry of Maritime Affairs and Fisheries. Control of reproduction to increase seed production through feed improvement, is one of the challenges and strategies in the mud crab aquaculture. Due to lack of knowledge about broodstock nutrition lead to producing rate of seeds still relatively low. This study aimed to obtain information on the kind of feed that has specific nutrient and plays a role in increasing the success of spawning and zoea survival. Mud crab of Scylla serrata with initial weight of 500.7±103.4 g, preferably under developed gonads were maintained in a fiber tank measuring length of 2.48 m, width 1.26 m, and a height of 60 cm which is partition sealed into 30×40×60 cm3 to put one crab. Tank was equipped with sand as a substrate as high as 15 cm and seawater system with flow rate of 1 L per six minutes and 25 cm high water. Treatments were consisted of: 1. PI (fresh meat fish of Decapterus sp. with dose of 5%), 2. PSC (fresh meat mixture of Decapterus sp. 1.8%, 3% of squid, and shrimp 1.2%), 3. PB (artificial feed dose of 10%) of BW, each treatment was repeated three times. Parameters measured were the duration of ovarian to mature, egg diameter, hatching rate, fecundity, and zoea production. Data were analyzed using ANOVA. The quality of larval measured by survival and larval fat and protein content. The results showed that crabs treated by PI and PSC showed faster to get mature compared to PB treatment (p<0.05). Hatching rate of larvae in PSC treatment was higher compared to PI and PB treatments (p<0.05). Furthermore, all treatments did not affect egg diameter, fecundity, and the number of zoea (p>0.05). In conclusion, crab which fed fresh meat (PI and PSC) could get mature earlier, and have high percentage of the larval hatching than those of fed by PB. In fact that larvae from broodstock feed of PI has survival as well as protein and fat content were higher than those of fed by PB.Keywords: spawning perform, broodstock feed, mud crab (Scylla serrata)

Abstract

Marine debris in the waters has become a significant environmental issue, threatening the balance and function of coastal and marine ecosystems, including mangrove ecosystems. Poka Beach in the inner Ambon Bay is facing the accumulation of waste from local activities and external currents. To address this issue, the Community Service Program from the Faculty of Fisheries and Marine Sciences at Pattimura University organised a coastal cleanup and mangrove rehabilitation at Poka Beach, involving students, the community, and related institutions. This program aims to raise awareness about the threat of marine debris and the role of mangroves in the sustainability of coastal and marine environments and ecosystems. The Community Service activities include site surveys, coordination with relevant parties, beach clean-up actions, and replanting mangrove seedlings. This activity successfully collected various marine debris accumulated at Poka Beach, such as bottles, food packaging, and household items. Amounting 180 kg of plastic waste was sent to the waste bank for recycling. As many as 150 mangrove seedlings were planted at a distance of 1 meter along the 200-meter stretch of Poka Beach. The sustainability of similar programs through education, conservation, community empowerment, and cross-sector collaboration must be carried out to change community behaviour in proper plastic waste management and create cleaner and healthier coastal and marine environments.

Abstract

Mud crab (Scylla spp.) is one of the coastal fisheries resources that has important economic value. Along with the increasing market demand for mud crabs, the development of mud crab aquaculture is widely practiced in various coastal areas in Indonesia. The availability of local resource-based feed is one of the key factors for the efficiency of aquaculture efforts and the sustainability of mangrove crab aquaculture production in the region. This study aimed to examine the effect of a combination of unripe papaya fruit and fish flesh (Decapterus sp.) with different ratios on the growth of young mud crab cultured using the floating raft method in the Tuhaha Bay waters, Tuhaha Village, East Saparua District. A total of 12 mud crab were fed a mixture of papaya and fish at 10% per total body weight per day. Treatment A (5% papaya: 5% fish flesh) and treatment B (7.5% papaya: 2.5% fish flesh) were given to six individual mud crabs each. Weight measurements were taken weekly during the one-month study period. The results showed that young mud crab fed treatment B tended to have higher absolute weight growth rate and specific growth rate compared to juvenile mud crab fed treatment A but were not statistically significantly different. This finding explains that the composition of 25%-50% unripe papaya fruit combined with fish flesh (Decapterus sp.) effectively increases the growth rate of the mud crabs.

Abstract

Biofloc is one of the advances in fish farming technology with the main principle of recycling nutrients into the culture system. Biofloc application has been widely used in freshwater aquaculture systems, but in seawater aquaculture systems it is still very limited. This study evaluated the application of bioflocs with different bacterial sources, EM4_Fishery and Nitrobac, on the growth and survival of White Snapper (Lates calcalifer) and the water quality of the aquaculture environment. This study used a completely randomised design (CRD) with three replications. A total of 19 White Snapper fish with an average weight of 6.86±0.17 g/L were put into each 14-day-old biofloc and control. Feeding was 2% of total body weight with a frequency of once a day (09.00 am). The results showed that during the experimental period, the weight of White Snapper fish decreased variably in both treatments and controls. The survival rate of White Snapper fish in the Nitrobac bacteria treatment tended to be higher than in the EM4_Fishery bacteria, but both were lower than the control with a tendency for large fish to survive longer than small fish. Concentrations of ammonia, nitrite and nitrate in the treatments at the beginning of the experiment were higher than the control but tended to decrease with the length of rearing. DO values tended to increase in the treatments compared to the control, while DO values tended to increase in the treatments compared to the control. These findings revealed that the Nitrobac as a source of biofloc bacteria in marine White Snapper culture is more effective than EM4_Fisheries, but requiring further experiments with some concern on individual fish size greater than 7 g and the biofloc older than two weeks is recommended.

Abstract

Penelitian ini bertujuan untuk membandingkan tingkat efektivitas konsentrasi dari bahan pembius minyak cengkih (Eugenia aromatica) dan ekstrak akar tuba (Deris eliptika) terhadap masa induktif dan sedatif serta pengaruhya bagi tingkat kelulus-hidupan benih ikan Nila Orochromis niloticus. Penelitian bersifat eksperimental menggunakan RAL dengan 3 perlakuan konsentrasi (15%, 20%, dan 25%), dan 3 ulangan pada masing-masing bahan pembius. Data dianalisis secara statistik deskriptif dan ditampilkan dalam bentuk tabel dan grafik. Hasil penelitian menunjukkan bahwa konsentrasi minyak cengkih yang efektif terhadap masa induktif dan masa sedatif benih ikan nila selama penyimpanan 4 jam yaitu 0.15%, dengan persentasi kelulus-hidupan mencapai 97.8±3.8%. Sementara itu dengan konsentrasi yang sama dari ekstrak akar tuba menunjukkan persentasi kelulusan hidup benih ikan nila hanya mencapai 46.6±6.3%. Dari hasil penelitian ini dapat disimpulkan bahwa penggunaan konsentrasi 0,15% minyak cengkih efektif untuk pembiusan benih ikan nila selama 4 jam. Ekstrak akar tuba belum dapat direkomendasikan penggunaannya karena perlu menemukan konsentrasi dibawah 0,15% terhadap persentasi kelulusan hidup benih ikan nila hingga mencapai lebih besar dari 50%.

Abstract

Rumput laut merupakan salah satu sumber daya hayati laut yang memiliki nilai strategis sebagai bahan pangan, energi alternatif, serta agen ekologis dalam menjaga keseimbangan lingkungan. Potensi ini sangat relevan diperkenalkan kepada generasi muda, khususnya siswa SMA, untuk membangun kesadaran sains dan lingkungan berbasis sumber daya lokal yang melimpah di wilayah Maluku. Edukasi berbasis rumput laut diharapkan dapat memperkuat literasi ekologis sekaligus menumbuhkan sikap peduli lingkungan pada peserta didik. Kegiatan ini bertujuan untuk meningkatkan pemahaman siswa kelas XI IPA 1 SMA Negeri 3 Ambon mengenai manfaat dan peluang pemanfaatan rumput laut dalam mendukung ketahanan pangan, energi terbarukan, serta mitigasi perubahan iklim. Metode pelaksanaan dirancang secara edukatif melalui tahap persiapan, sosialisasi tatap muka, dan evaluasi dengan instrumen pre-test dan post-test. Materi disampaikan secara interaktif menggunakan media visual berupa slide, infografis, dan diskusi kontekstual. Hasil kegiatan menunjukkan adanya peningkatan signifikan dalam pemahaman siswa terhadap definisi, fungsi ekologis, dan pemanfaatan aplikatif rumput laut. Sebelum kegiatan, mayoritas siswa hanya memahami rumput laut sebatas organisme laut yang bermanfaat secara umum, sedangkan setelah sosialisasi terjadi peningkatan pemahaman mendalam terkait fungsi ekologis sebagai penyerap karbon, penyaring logam berat, hingga potensi pengembangan bioenergi dan bioplastik. Siswa juga menunjukkan antusiasme tinggi, tercermin dari partisipasi aktif dalam diskusi dan refleksi akhir kegiatan. Dengan demikian, kegiatan ini terbukti efektif dalam meningkatkan literasi sains, kesadaran ekologis, serta wawasan siswa mengenai potensi rumput laut sebagai solusi pangan dan energi berkelanjutan.
