Abstract Rokan Hilir Regency is situated east coast of Sumatera in Riau Province. Fish production of the area dominated by capture fisheries (80.67%) compared to aquaculture production (19.33%), however, there is a demand for strengthening the role of aquacuture. This study aimed to analyze the prospects and strategies for developing aquaculture in this area. Primary data was obtained by measuring of water quality, observations of aquaculture objects and other supporting facilities. Interviews and discussion were conducted with fish farmers, community leaders, the fishing industry, local government officials and other stakeholders. Secondary data were obtained from government and private institutions. This area has the potential for freshwater aquaculture of 102.80 ha, brackishwater aquaculture of 3,049.25 ha, and marine aquaculture of 118.330 ha. In 2019, aquaculture only utilized an area of around 2,879,107 ha, including 47,107 ha of freshwater (ponds), 10 ha of brackish, and 2,822 ha of shellfish ponds. Aquaculture production in 2019 was 15,006.34 tons consisting of fish production from ponds (blood clams and shrimp) 9,009.34 tons which was the main production, followed by fish production from ponds of 5,997 tons. In coastal waters, it is recommended to cultivate blood cockles and Pacific white shrimp (Litopenaeus vannamei). While in inland waters, the recommended fish culture included tilapia (Oreochromis niloticus), striped catfish (Pangasianodon sp), kissing gouramy (Osphronemus sp), and African catfish (Clarias gariepenus), both in ponds and floating net cages. The recommended development strategies include; training on aquaculture human resources, training on making their own feed, building seed and brood centers, and providing business stimulants in the form of seeds, making ponds and floating net cages as well as sustainable guidance from the fisheries industry and the government.

ABSTRACTThis study was conducted to evaluate the digestibility of biofloc meal collected from catfish culture as a feed raw material for Pacific white shrimp Litopenaeus vannamei diet. A basal feed with 43% crude protein content was used as a control diet and mixed with 2% of binders and 0.5 % of Cr2O3 as a marker for digestibility. The experimental diets were made by mixing 67.5% of the basal diet with 30% of biofloc meal, 2% of binders and 0.5 % of Cr2O3. Nine units of glass tanks (90 cm ×40 cm× 35 cm) filled with 100 L seawater were used as the experimental culture units. White shrimp with an average body weight of 5.61 ± 0.09 g was randomly distributed to each experimental tank at a density of 20 shrimp/tank. The feed was offered at a level of 5% shrimp biomass per day at a frequency of four times a day. The results showed that the dry matter digestibility of feed with 30% biofloc meal in shrimp were similar to that of the reference diet. However, protein and fat digestibility of feed containing biofloc meal were considerably higher than those of the reference diet. Feeding shrimp with 30% biofloc meal diet resulted in higher survival and specific growth rate and lower feed conversion ratio than those of the control. The digestibility of bioflocs dry matter, protein and lipid in Pacific white shrimp obtained in this study were 54.9%, 76.3% and 79.3%, respectively.Keywords: biofloc, digestibility, catfish, shrimp  ABSTRAKPenelitian ini dilakukan untuk mengevaluasi kecernaan tepung bioflok yang diambil dari media pemeliharaan ikan lele sebagai bahan pakan udang vaname Litopenaeus vannamei. Pakan yang mengandung kadar protein 43% digunakan sebagai pakan control dan dicampur dengan 2% binder dan 0.5% Cr2O3 sebagai marker untuk kecernaan. Pakan perlakuan dibuat dengan mencampurkan 67.5% pakan control dengan 30% tepung bioflok, 2% binder dan 0.5% Cr2O3. Penelitian menggunakan sembilan unit akuarium (90 cm ×40 cm ×35 cm) yang diisi 100 L air laut. Udang vaname dengan bobot rata-rata 5.61 ± 0.09 g ditebar secara acak pada setiap akuarium perlakuan pada kepadatan 20 ekor/akuarium. Pakan diberikan dengan tingkat pemberian pakan 5% biomassa per hari sebanyak empat kali sehari. Hasil penelitian ini menunjukkan bahwa kecernaan pakan dengan 30% tepung bioflok tidak berbeda nyata dengan pakan acuan. Namun kecernaan protein dan lemak pakan yang mengandung tepung bioflok terlihat lebih tinggi daripada pakan kontrol. Pemberian pakan dengan tepung bioflok sebanyak 30% juga menghasilkan tingkat kelangsungan hidup, laju pertumbuhan spesifik udang dan rasio konversi pakan yang lebih baik daripada udang yang diberi pakan kontrol. Kecernaan bahan, protein dan lemak tepung bioflok pada udang yang didapat dalam penelitian masing-masing adalah 54.9%, 76.3% dan 79.3%.Kata-kata kunci: bioflok, ikan lele, kecernaan, udang

AbstractDevelopment of a blue economy is firmly embedded in the development plans of Bangladesh. Advances in freshwater aquaculture have promoted Bangladesh to the fifth largest fish producer in the world. However, the marine resource base of Bangladesh, which is now even greater following the recent settling of disputes regarding maritime boundaries with neighbouring countries, lends itself to the development of marine aquaculture—known as mariculture. Several potential areas and opportunities for mariculture development have been identified for implementation under the concept of blue economy development in Bangladesh. We identify the most promising fish species as the hilsa shad (Tenualosa ilisha), seabass (Lates calcarifer) and the grey mullet (Mugil cephalus), and the shrimp species as black tiger shrimp (Penaeus monodon), brown shrimp (Metapenaeus monoceros), Indian white shrimp (Penaeus indicus) and the mud crab (Scylla serata). Further, some non-traditional marine species like seaweed, microalgae, shellfish (mussel, oyster) and the sea cucumber offer considerable potential. However, there remain major challenges and constraints that need to be addressed in order for mariculture to further develop and contribute to a growing blue economy in Bangladesh. Most notably, ministries, departments and research institutions, along with interested private entrepreneurs, must collaborate to formulate strategies for effective development and implementation, so that mariculture can contribute to food security and economic development through export opportunities.

Tanzania endowed with abundant water resources with a huge potential to develop marine and freshwater aquaculture. Efficient utilization of these resources are required as the demand of fish is increasing with increase in the population of an average of 2.47% per year. Due to that, a gap between fish supply and demand is widening which in turn causes low fish protein supply leading to malnutrition. To bridge this gap, several strategies have been implemented by the government including fish importation to supplement fish shortage in country. However, this strategy seems to be unable to satisfy the fish demand of the large population due to high importation costs. Therefore, a review was conducted to explore recent aquaculture production in Tanzania, challenges and opportunities, different strategies implemented, as well as impacts in poverty alleviation. Several government reports and online-published papers were explored. Therefore, this review indicates a remarkable increased in fish production due to fish species diversification, government support and private sector investment. Hence, provide more opportunities to the people to be employed and earn money, as well as availability of protein from fish to improve their nutrition status. In addition, this review suggest some areas to be emphasized including; development of technology and investment in seeds and feeds production, investigation of alternative protein sources for fish, policies harmonization, and financing mechanism development.

Abstract Inner Ambon Bay is used for fishery research by the government. One of the species that has been cultivated is seabass because it has high economic value. Seabass cultivation in floating net cages has been developed by Ambon Marine Aquaculture Institute (BPBL-Ambon). The characteristics of seawater in Inner Ambon Bay (IAB) based on the observation data in the project “Ocean Current System of Indonesia Waters and Its Effect on Marine Fisheries Production” in May 2017 show that the temperature is in the range 29.8 – 30.9 °C. Meanwhile the salinity is about 26.1–31.4 PSU and the chlorophyll concentrations as much as 0.88 – 3.61 mg/m3. The 1D ecosystem model simulation is performed to know how is the growth rate of seabass is with two-way interaction between nutrient, phytoplankton, zooplankton, and detritus (NPZD) towards zooplanktontivor (fishes which consume zooplankton). The verification of model result (fish mass) with the observation data of fish mass which conduct by BPBL Ambon show the RMSE value is 0.001 kg and the correlation is 0.99. The nutrient concentration since 2016 – 2018 in the range of 3.08 – 3.78 mmolC/m3. While the phytoplankton, zooplankton, and detritus concentration during 3 years each one is 4.67 – 5.84, 11.53 – 15.77, and 16.88 – 20.67 mmolC/m3. The fastest growth rate of Seabass with the first scenario is 1.52 grams/day with the duration of 257 days and when the juvenile of seabass spread in January. The fastest growth rate of Seabass with addition feed is 2,23 grams/day during 175 days.

Integrated Community Partnership Program (PKM) activities of lobster and pearl shells with the aim of increasing marine aquaculture production through the application and development of integrated aquaculture technologies. In addition, this activity is expected to increase knowledge and skills in productive economic business activities. In addition, this activity is expected to increase knowledge and skills in productive economic business activities. The method of implementing PKM is the method of demonstration plot, where the target community groups play an active role at all stages of activities. Implementation of activities offered to support the realization of PKM activities with steps that have been mutually agreed upon include strengthening and socializing PKM activities, training, strengthening institutional management, demonstration plots of integrated system cultivation and coaching and mentoring. The results of PKM activities provide a positive value for the target community, with integrated aquaculture production of floating net cages (KJA) in the sea no longer relying on one commodity, but one KJA unit can produce two commodities namely lobster (Panulirus homarus) and pearl shells (Pinctada maxima). Thus the potential to provide additional income for the community from these two commodities. In addition, through this PKM activity, it is expected that the knowledge and skills of the target communities will increase in order to strengthen community partnerships.

Individual Taxpayers (WPOP) experience problems every year due to difficulties in filling out SPT. The Directorate General of Taxes issued a new policy in providing easy Notification Services (SPT) using online systems namely e-Filling and e-SPT. The policy taken by the government turned out that there were still many obstacles faced by the KPP Pratama Ponorogo Tax Office regarding ponorogo's lack of understanding related to filling out SPT manually or online using e-SPT and e-Felling. So that this certainly can make taxpayers object to the submission of Annual Tax Returns, especially in terms of calculating the tax payable which must be calculated on its own. Data collection is done by using primary data in the form of questionnaires. The samples processed in this study were 100 respondents who were distributed to individual taxpayers registered at KPP Pratama Ponorogo. Data analysis method uses validity test and reliability test, hypothesis testing using multiple linear regression analysis. The results of this study indicate that the awareness of taxpayers, taxpayer intentions, taxpayer attitudes, subjective norms, behavioral control and ease of tax return filling process affect Tax Compliance (tax compliance) submission of Annual Tax Returns. This is because taxpayers know, understand and implement taxation provisions correctly and voluntarily so as to increase taxpayer compliance in fulfilling their obligations and are willing to report taxes with their own awareness.
