Aquaculture in Brazil probably started the 17th century, during Dutch occupation of northeastern region. Currently, this activity can be divided into five main sectors, defined by tradition and type cultured organism: freshwater fish, marine shrimp, mollusks, prawns frogs. Production 2019 was estimated at 800,000 tonnes, representing a gross revenue US$ 1 billion. Freshwater fish is predominantly produced, followed shrimp. The farmed species are Nile tilapia (Oreochromis niloticus), tambaqui (Colossoma macropomum) Pacific white leg shrimp (Litopenaeus vannamei). Other have great local socio-economic importance. bulk production comes from small farms: more than 80 % less 2 ha. has 200 thousand farms, about 3000 100 aquaculture research institutions.

Tilapia introduction in China: Economic boom in aquaculture versus ecological threats to ecosystems

Abstract The introduction and use of non‐native species in aquaculture have played a central role the development this economic sector worldwide. Tilapia is one most widely introduced world, China has become largest producer consumer tilapia. While tilapia support provisioning ecosystem services substantial value, invasion also poses potential threats to native fish diversity, ecosystems ultimately sustainable fisheries development. However, knowledge regarding invading pathway, development, benefits ecological impacts such important still limited, especially China. Based on thorough literature review as well field surveys, paper comprehensively presented across range aquatic habitats its industry growth, emphasising In addition, we synthesised negative caused by with global evidences, which will provide excellent lessons management recommendations for other countries Future trends tend indicate an increase number frequency tilapia's China, increasing likelihood environmental impacts. it apparent that tilapias highly profitable activity makes introductions inevitable, therefore, alternative strategies implications are further discussed seek achieve more ecosystem‐friendly aquaculture, reduce risks while maintaining benefits.

Managing exploitation of freshwater species and aggregates to protect and restore freshwater biodiversity

Environmental Reviews, Год журнала: 2023, Номер 32(3), С. 414 - 437

For millennia humans have extracted biological and physical resources from the planet to sustain societies enable development of technology infrastructure. Growth in human population changing consumption patterns increased footprint on ecosystems their biodiversity, including fresh waters. Freshwater biodiversity face many threats it is now widely accepted that we are a crisis. One means protecting restoring freshwater better manage exploitation biota aggregate (e.g., sand, gravel, boulders). Here outline arising such identify response options ensure methods levels extraction sustainable allow recovery over-exploited ecosystems. The guidance provide will practitioners, policy-makers, resource stewards embrace effective, sustainable, evidence-based approaches extraction. Response for managing species include strengthening assessment reporting, using science-based reduce overexploitation support recovery, embracing community engagement, building or tightening legislation. reducing demand harvest, governance, monitoring environmental impacts, promoting restoration degraded compensating losses. Diverse case studies highlight examples where various management actions been implemented an effort consider how they can be scaled up adapted other contexts. Managing key aspect broader initiatives needed protect restore around globe.

Aquaculture production and diversification: What causes what?

Aquaculture, Год журнала: 2024, Номер 583, С. 740626 - 740626

Опубликована: Янв. 25, 2024

Aquaculture, an important source of food supply, is expected to be the main sector satisfy growing seafood demand in future. Being most diversified product world, aquaculture diversification can add resilience global security, consumer preferences, and promote price stability. Understanding relationships between production their causations crucial for developing effective strategies support long-term sustainability development. This study investigates direction causal using a panel vector autoregression (PVAR) model with three decades data Effective Number Species (ENS) values by country. Diversification measured terms within-group diversity (ENSα) between-group (ENSβ); this approach provides deeper insights into strategies. The results show that more conducive expansion globally, especially Americas Asia, positive effects are long lasting. Within-group also induces Europe and, lesser extent, Asia. Therefore, policies market incentives across different species groups within same group potential expand production. Other findings include leading Asia Europe, but not Africa. A possible explanation would accumulate experience, develop scope economies emerging technologies, build up capacities. These factors generate spillover facilitate diversification, considering have longer history development compared However, no significant relationship found diversification.

Fish culture in biofloc technology (BFT): Insights on stocking density carbon sources, C/N ratio, fish nutrition and health

Aquaculture and Fisheries, Год журнала: 2022, Номер 9(4), С. 522 - 533

Опубликована: Окт. 20, 2022

The growth of aquaculture demands intense consumption formulated foods, scarce natural resources such as water and land. increase in production needs to be sustainable several aspects the activity, including use more farming systems that provide reduced demand, less space dependence for increased production, availability complementary food. In this perspective, biofloc system (BFT), presents itself a friendly cultivation technology way mitigate some impacts production. Much research has been carried out, addressing different important fish BFT. review, we address how stocking density, carbon sources nitrogen ration (C/N) affect animal performance nutritional value bioflocs; microbial aggregates "in situ" "ex food benefits feed conversion, their influence on immune disease resistance.

ECOLOGIA DE PEIXES EM RIACHOS URBANOS

Oecologia Australis, Год журнала: 2021, Номер 25(02), С. 588 - 604

Опубликована: Июнь 16, 2021

The development of agriculture allowed humans to congregate in settlements which developed into the modern urban societies. This urbanization process caused profound habitat changes, giving rise ecosystems where structure, functioning and dynamics ecosystem are determined by human activities. Despite increasing rates worldwide,the ecology is poorly known. In this chapter, we focus on stream expose current advances fish ecology. We explore topics concerning biodiversity,ecological interactions adaptation systems. also different approaches methodologies for study fish. Our goal introduce theoretical background analytical tools fishes with intent facilitating future research
