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. A large domestic market available for edible shellfish, ornamentals, baitfish hatchery-reared juveniles biomitigation purposes. challenge to develop truly sustainable systems support perennial industry. New technologies, including digital devices simple disruptive innovations, increase productivity shift circular economy, bioeconomics sustainability supported science-based innovations knowledge.

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

Reviews in Aquaculture, Journal Year: 2022, Volume and Issue: 15(1), P. 179 - 197

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, Journal Year: 2023, Volume and Issue: 32(3), P. 414 - 437

Published: Aug. 2, 2023

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.

Aquaculture production and diversification: What causes what?

Aquaculture, Journal Year: 2024, Volume and Issue: 583, P. 740626 - 740626

Published: Jan. 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, Journal Year: 2022, Volume and Issue: 9(4), P. 522 - 533

Published: Oct. 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.

Climate change may increase the suitable habitats for invasive freshwater Cichlids in a Neotropical basin

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 2, 2025

Climate change is considered a driver for the spread of invasive alien species (IAS); nevertheless, research assessing this link remains limited. Recognizing suitable habitats where IAS have been introduced crucial biodiversity conservation and ecosystem management. Here, we integrated online, museum, laboratory occurrence databases with local ecological knowledge (LEK) on fishes from semi-structured interviews georeferenced Instagram posts traditional recreational fishers to model habitat-suitability three voracious Cichlids in Brazilian part Upper Paraguay River Basin (the Pantanal wetland its tributaries). Our goal was locate areas (regions, sub-basins, reservoirs) most at risk these basin. findings reveal extensive throughout study basin, currently covering half up 90% upstream sub-basins. Under future climate scenarios, are projected expand further, encompassing 85% floodplain - one fish-rich basins Neotropical region (~ 300 spp). These underscore potential Cichlid range expansion floodplains upcoming decades. emphasizes value integrating Ecological Niche Models (ENMs) Citizen Science data identify high-risk during early invasion stages, inform preventive strategies, support efforts mitigate impacts native biodiversity.
