Abstract Aim Aquaculture plays an important role in the world and in Brazil. Artificial construction of water bodies, such as ponds and reservoirs, has allowed for fish culture in cages in those environments, generating conflicts over the use of these public waters. The producers are seeking to increase production, and the ecosystem is susceptible to the impacts caused by production activity. The aim of this review was to identify questions about these conflicts (productivity × environment) and to indicate possible solutions to the main problems related to fish farming in reservoirs. Methods A bibliographical survey was carried out on the main aspects of cage fish farming in Brazilian reservoirs. Studies from 1977 to 2018 (scientific journals, books, and thesis) were revised using seven databases, the CAPES periodicals portal and Google Scholar websites. The main keywords used were “aquaculture”, “reservoir”, “cage”, “eutrophication”, “carrying capacity”, “impacts”, “oligotrophic”, “escapes”, “hybrids”, and “pollution”. Results We accessed approximately 330 and cited 151 documents. Conclusions The negative aspects associated with cage fish farming, as escapes of cultivated fish, and the possible solutions of this and others negative impacts were addressed, identifying mechanisms for reducing conflicts between environmental impacts and aquaculture production. Potential solutions include the use of native fish species or sterile species, implementation of monitoring systems of the surrounding area, adoption of measures to reduce the accidental escape of fish, use of multitrophic culture systems, use of highly digestible diets with appropriate food management, and use of computer programs that incorporate current and historical environmental data to calculate carrying capacity and choose the most appropriate location for production.

OBJECTIVES: This study aimed to verify the influence of net-cage fish farming on zooplankton biomass in the Itá reservoir (Uruguay River, Brazil). METHODS: Samples were collected monthly from October/2009 to May/2010 at the surface and at the bottom in two sampling stations, the net-cage area and in a control area using a Van Dorn bottle and a plankton net (68 µm). RESULTS: The Cladocera and Copepoda biomass was estimated by dry weight using a micro-analytical balance, and the Rotifera biomass by Biovolume. Total zooplankton biomass varied between 6.47 and 131.56 mgDW.m-3 Calanoida copepod presented the highest value of biomass (127.56 mgDW.m-3) and rotifers, despite having an important contribution to total density, showed a maximum biomass of 2.01 mgDW.m-3. Zooplankton biomass at the net-cage area surface was higher when compared with the control area during the months of October to January. However, the zooplankton biomass was similar at the bottom of the two areas throughout the studied period. From February until May, zooplankton biomass decreased in both sampling stations, a fact probably associated with the flushing of the reservoir, followed by an increase in water transparency and a decrease in chlorophyll-a concentration in the following months (February to May). CONCLUSIONS: The influence of fish farming on zooplankton biomass was detected at the surface of the net-cage area only from October to January. From February to May this influence was not found, probably by the influence of the flushing of the reservoir.

AbstrakDanau merupakan salah satu bentuk ekosistem yang menempati daerah yang relatif kecil pada permukaan bumi dibandingkan dengan habitat laut dan daratan. Bagi manusia kepentingannya jauh lebih berarti dibandingkan dengan luas daerahnya. Sejak tahun 1985 Danau Teluk di Kota Jambi mulai digunakan sebagai lokasi budidaya ikan dengan karamba jaring apung (KJA) dengan jumlah KJA yang beroperasi pada tahun 2012 mencapai + 878 unit dari 64 pembudidaya ikan dan akan meningkat terkait penetapan Propinsi Jambi sebagai salah satu kawasan minapolitan perikanan budidaya guna peningkatan produksi perikanan. Pemanfaatan Danau Teluk sebagai media untuk budidaya ikan di KJA diperlukan upaya untuk mendorong pengelolaan terhadap sumberdaya milik umum ini agar terus bekelanjutan. Kajian mengenai dukung perairan dan pemanfaatan daya Danau Teluk Kota Jambi untuk budidaya ikan sistem KJA bertujuan untuk mengetahui daya dukung Danau Teluk yang digunakan untuk kegiatan budidaya ikan di KJA, bagaimana deskripsi pemanfaatan danau untuk budidaya ikan di KJAyang selama ini dilaksanakan oleh masyarakat sekitar dan merumuskan pola pemanfaatan Danau Teluk untuk budidaya ikan di KJA yang berbasis masyarakat secara berkelanjutan. Hasil penelitian menunjukkan  bahwa  daya dukung perairan Danau Teluk Kota Jambi untuk budidaya ikan di KJA adalah sebesar 517,617 ton ikan  per tahun dengan estimasi jumlah pakan di KJA yang diberikan pada ikan sebanyak 931,710 ton pakan ikan per tahun dengan asumsi kadar total P yang masuk ke perairan danau melalui limbah ikan sebanyak 20 kg P/ ton ikan. Jumlah ideal unit KJA yang seharusnya beroperasi di Danau Teluk berdasarkan penghitungan daya dukung danau sebanyak 862, 695 unit ~ 862 unit. Saat ini jumlah KJA yang beroperasi adalah sebanyak 878 unit sehingga perlu dilakukan pengurangan jumlah sebanyak 16 unit. Pemanfaatan Danau Teluk untuk budidaya ikan oleh masyarakat dilakukan secara sederhana dan jumlah KJA yang terdapat ternyata sudah sedikit melebihi daya dukung perairan jika dilihat dari konsentasi Total P yang ada di perairan. Peningkatan jumlah KJA yang ada di danau perlu mendapat perhatian dari pemerintah dan masyarakat setempat. Pola pemanfaatan danau untuk budidaya ikan berbasis masyarakat yang direkomendasikan adalah dengan mengeluarkan ijin usaha budidaya ikan agar kegiatan budidaya ikan dapat terkendali dan tidak merusak lingkungan, menggunakan pola pemeliharaan ikan dengan jaring ganda sehingga biaya operasional lebih efisien dan produksi ikan dapat ditingkatkan, membuat manajemen pakan dalam penerapan budidaya ikan dalam KJA, meningkatkan SDM pembudidaya ikan dan mengaktifkan kembali kelompok pembudidaya ikan sehingga koordinasi antar pembudidaya, pemerintah dan stakeholder terkait dapat terjalin serta pengaturan tata ruang KJA.Kata Kunci : pemanfaatan danau, daya dukung, Danau Teluk, budidaya ikan KJA, berbasis masyarakatAbstracLake is one of ecosytem form than occupies a relative small area on the surface of the earth as compared to sea and land habitats. For humans, utilization  is more important than the expanse of lands. Since 1985, Teluk Lake began to be used as the location of fish cultivation with floating net cage culture (FNCC). The number of FNCC in 2012 reached ± 878 unit of 64 fish farmers and it will increase related to determination of Jambi Province as one of Minapolitan fishery cultivation in order to increase fish production. Utilization of Teluk Lake as media for fish cultivation on floating cage is necessary to encourage the management of common resources is to be kept sustainable.  Studies on carrying capacity and utilization of Teluk Lake Jambi City for community-based fish cultivation on FNCC aims to know how the use of this lake that have been implemented by the local community and to find out patterns of Teluk Lake utilization to fish culture in floating cage sustainable community-based  and to find out how the carrying capacity Teluk lake that used to fish farming activities in floating cage. Methods used in this study is qualitative and quantitative methods with a descriptive approach. 1Result showed that carrying capacity of Teluk lake for fish farming in FNCC is equal  517,617 tons of  fish per year with estimate amount of feed given to fish in floating cage is as many as  931,710 ton per year assuming total P were entered into the lake through fish waste as much 20 k P/ton of fish. Ideal number of floating cage based on lake  carrying capacity accounting should be 862,695 unit ~ 862 unit. Operating floating cage currently  is  878 unit so that it is necessary reduction in the amount of 16 unit and if they want to add a new one, it should be an improvement or replacement of existing floating cage at lake. Utilization of Teluk Lake for fish farming is done simple by local communities and number of existing floating cage already slightly exceed the carrying capacity of lake if related from existing concentration of total P in water. The increasing amount of floating cages in lake should be attend from goverment and local communities, so it is necessary to manage the use of lake for fish cultivation. Pattern of lake utilization for fish farming  based- community ist recommended to issue a business licence, in order to control fish farming activity, and not damage the environment, using growt out pattern by double nets so that more efficient operating cost and fish production can be increased, making management of feed in fish farming at floating cage, develop capability of human resouces, activate again POKDAKAN so coordination between farmers, goverment and stakeholder can be build and layout arrangement FNCC.

Cage fish farming in Indian reservoirs has the potential to enhance the reservoir production manifold. The present study estimated that around 14,000 cages have been installed in different reservoirs of the country which are producing around 16% of the current reservoir fish production. Around 7.5 lakh mandays of labour are being generated by cage fish farming in the country. An empirical study in the state of Jharkhand State found that the adoption of cage culture contributed around 30% to the livelihood of fishers. Cage culture not only increased monthly family income but also reduced the occupational migration. The fishermen households who adopted cage farming also accumulated some durable assets due to improvement in household income. However, high initial cost of cage culture operation, high feed cost and low market price of cultured pangas fish (Pangasianodon hypophthalmus) were some of the major constraints in adopting the technology as reported by the fishers. The study recommends that the state departments need to promote the use of low cost galvanised iron(GI) cages designed by the ICAR-Central Inland Fisheries Research Institute (ICAR-CIFRI) in reservoirs which may play a significant role in fulfilling the vision of blue revolution in the country.
