Abstract

Oyster shell can be used as alternative calcium source. Utilizing of oyster shell into nano calcium flour can be used to decrease solid waste. The usage of nano calcium flour in feed is important applied as calcium supplements with cherax quadricarinatus. The purpose of this research is to study the effect of nano calcium addition on feeds to increase moulting frequency, survival and growth rate of freshwater lobster. This research has been done during 60 days in fisheries Laboratory, Abulyatama University. Two percents nano calcium addition on feeds gives significant effect on growth rate and very significant effect to moulting frequency of freshwater lobster. Which has moulting frequency 2.71. Where the treatment was not added nano calcium has moulted frequency 1.29. But, nano calcium addition on foods did not affect survival rate.Cangkang tiram dapat digunakan sebagai alternatif sumber kalsium. Pemanfaatan cangkang tiram menjadi serbuk nanokalsium dapat mengurangi limbah padat. Penggunaan serbuk nanokalsium pada pakan penting dilakukan sebagai suplemen kalsium untuk lobster air tawar. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan nanokalsium pada pakan terhadap pertumbuhan, frekuensi molting dan kelangsungan hidup Lobster Air Tawar (LAT). Penelitian ini dilakukan selama 60 hari di laboratorium perikanan, Universitas Abulyatama. Data dianalisa menggunakan uji T (perbandingan) antara lobster yang diberi pakan nanokalsium dan tanpa penambahan nanokalsium. Nanokalsium yang ditambahkan ke dalam pakan sebanyak 2% berpengaruh nyata terhadap pertumbuhan lobster air tawar (thitung ttabel), dan berpengaruh sangat nyata terhadap jumlah molting dengan frekuensi molting 2,71 kali/ekor terhadap lobster yang diberi pakan nano CaO, sedangkan yang diberi pakan komersil hanya 1,29 kali/ekor. Namun, tidak berpengaruh terhadap tingkat kelangsungan hidup (thitung ttabel).

Abstract

Fishery management is an activity that must be carried out to achieve sustainable fisheries. Fisheries management using the Ecosystem Approach to Fisheries Management (EAFM) approach is the sustainable use of fishery resources and protection of fish stocks in nature. One of the objectives of fisheries management in social and economic aspects is how fisheries can ensure the socio-economic welfare of the fishing community. Using fishing gear that is not environmentally friendly is one of the triggers for social conflict between fishermen and the uncertain selling price when the peak season of fish impacted the fishermen's economy. Therefore, the purpose of this research is to examine the socio-economic domain indicators from the aspect of EAFM-based coastal and marine resource ecosystem management. This research was conducted from January to February 2021, located in Simeulue District, Sub-District East Simeulue. The data collection method used in the study was interviews and field surveys. The determination of respondents is done by using a gradual sampling technique or stratified random sampling. Data analysis uses an ordinal-based Likert score of 1,2,3 for each indicator, namely the economic domain, fishery household income (RTP), savings ratio, asset ownership, and the social domain, namely stakeholder participation fisheries conflict and the use of local knowledge in fish resource management. Management status in East Simeulue District assessed the aggregate value of the economic domain in the medium category with a score of 48.3. Fishermen still earn less than the minimum wage, while in the social domain, it is in the excellent category with a score of 100 because fishermen, institutions, and related agencies work with each other. Keywords:EAFMEcosystem approachFishery management

Abstract

The high level of public consumption, balanced with the increasingly dense population globally, makes food waste more and more. Food waste is the second-largest contributor to waste in the world. Moreover, the lack of food waste management makes this condition even worse. This food waste can be found, one of which is in restaurants, school canteens, food courts, and others. Fermentation is the process of breaking down complex substances into simpler ones. A fermentation process can help process food waste into various products such as liquid organic fertilizer, compost, biogas, and raw material for fish feed. Through the fermentation process, food waste can be used as an alternative fish feed with high nutritional content to benefit fish cultivators. Fish need many nutrients for their bodies, with food waste that has been processed will meet the dietary needs of fish. The cultivators will benefit more from the cost of feed and the sale of fish that can meet consumer needs.Moreover, the demand for the fish market is increasing every year. Several factors play a role in the success of the food waste fermentation process and the quality of the resulting product to be converted into fish feed raw materials. These factors include incubation time, pH acidity, and microbial factors that can accelerate the spoilage of fish feed raw materials.Keywords:Fermentation,Restaurant wasteFish feedFactorsQuality of feed IngredientsLiterature review on fermentation factors of restaurant organic waste affecting feed quality

Abstract

Abstract. Yellowfin tuna (Thunnus albacores) is a large, pelagic, and migratory species of tuna that inhabits Moluccas Sea in Indonesia, and most sea environment worldwide. However, high fishing activities tend to happen in the Indonesia region and catch product appear to be decreasing. A better understanding of yellowfin tuna genetic diversity is required to plan better conservation strategy of tuna. The study was conducted to infer the genetic diversity of yellowfin tuna (T. albacores) in the Moluccas Sea. A total of 41 tissue samples of yellowfin tuna were collected from two regions in the Moluccas Sea (North Moluccas and Ambon) during an expedition in February 2013. The results showed that genetic diversity and nucleotide diversity of yellowfin tuna from North Moluccas population was 0.984 and 0.021, respectively; while in Ambon population, the genetic and nucleotide diversities were 1.00 and 0.018, respectively. The high genetic diversity (0.990) and nucleotide diversity (0.020) between two populations were observed. Based on phylogenetic analysis, no genetic differentiation between the two populations in Moluccas Sea was revealed .Keywords :  Population genetics; Haplotype diversity; Coral Triangle; Phylogenetics; Polymerase Chain Reactions (PCRs) Abstrak.

Abstract

Study related to plankton community in the Banda Sea and its adjacent sea has been conducted by several authors; However, t information on the relationships between of plankton abundance and catches volume of yellowfin tuna Thunnus albacares has been never been examined. Therefore, the objective of this study was to analyze the relationships between plankton abundance and catch volume of yellowfin tuna in Banda Sea Waters, Ambon. The result showed that the highest abundance of phytoplankton (59.259 cell/m3) was found at station 10, around Ambon, Seram and Haruku Island which located in the waters between many river runoffs. While, the highest abundance of zooplankton was 5,483 ind/m3, located around Ambelau Island. Both diversity (H') and evenness (E) index of phytoplankton were at the medium level, and there were no dominant species in this observation. Based on visual observation of remote sensing data, there was an indication of a relationship between the area with high concentration of chlorophyll-a (high phytoplankton biomass) with CPUE value of yellowfin tuna.Studi mengenai komunitas plankton di Laut Banda dan sekitarnya telah banyak dilakukan, akan tetapi telaah hubungan antara kelimpahan dan distribusi plankton dengan aspek perikanan belum banyak dibahas. Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara kelimpahan dan distribusi dari komunitas plankton dengan perikanan tuna di Perairan Kepulauan Banda. Kelimpahan fitoplankton tertinggi terdapat pada stasiun 10 yang terletak di daerah antara pulau Ambon, Seram dan Haruku (59.259 sel/m3) yang mempunyai akses ke muara-muara sungai di sekitarnya. Sedangkan kelimpahan zooplankton tertinggi terletak di sekitar Pulau Ambelau (stasiun 3), yakni 5.483 ind/m3. Tingkat indeks keanekaragaman (H’) fitoplankton sedang, indek keseragaman (E) rendah hingga sedang, dan tidak ditemukan jenis tertentu yang dominan. Berdasarkan pengamatan visual data penginderaan jauh memberikan indikasi adanya keterkaitan antara daerah dengan konsentrasi klorofil-a yang tinggi (biomassa fitoplankton tinggi) dengan hasil tangkapan per unit upaya penangkapan tuna madidihang.

Abstract

One effort to reduce bycatch in togok is to modify the togok by creating a vent to reduce bycatch by BRD. The BRD installed on the togok was a rope BRD vent made of Polyethelene (PE) with a diameter of 2 mm. The rope BRD vent is attached to the top of the cod-end as an escape vent 25 x 50 cm. The escape vent and the stash cod-end are covered with a net with a mesh size of 5 mm. The cover net aims to collect data on fish catches that pass through the rope BRD vent. The percentage of fish that pass through the rope BRD vent can be calculated, and measure the size of the fish caught in the cod-end and covered as an indicator of the effectiveness of the rope BRD vent on togok. This experiment was carried out for 20 days of fishing operation and 40 hauls. The results showed that the catch of togok without rope BRD vent (conventional) and togok with modified rope BRD vent were different (p 0.05), where the catch of conventional togok was 468.34 kg, and the catch of modified togok was 305.235 kg. The fishing catches in the cod end and cover sections the most are bycatch with 51% and 54% of the percentage of the total catch, and the least in the cod end is the discarded catch, which is 21% of the percentage of the total catch and on the cover is the main catch (main catch) with 19% of the percentage of the total catch.The average size of the catch of togok species of fish is there are many immature sizes, and the average size of the catch of togok species of shrimp is there are in maturity size.Keywords:BycatchBycatch excluder device (BRD)DiscardMain catch
