Significance The incidental catch of threatened species is still one the main barriers to fisheries sustainability. What would happen if we closed 30% ocean fishing with goal reducing bycatch? Analyzing 15 different around globe, found that under static area management, such as classic no-take marine closures, observed bycatch could be reduced by 16%. However, dynamic management based on and closing same total but fragmented in smaller areas can move year year, reduction increase up 57% at...
Landing data are the most basic information used to manage fisheries, although they often unavailable or incomplete. The objective of this work was reconstruct national database marine commercial landings for Brazilian industrial and artisanal from 1950 2015. Total increased strongly mid-1980s suffered sharp decline in early 1990s, mainly associated collapse sardine fisheries. After that, another period increasing observed, but at a much lower rate. Industrial always surpassed waters, except...
The large pelagic species play an important role in transferring energy vast distant marine ecoregions. Results obtained report on extraordinary findings of commercial southeast–south Brazilian waters, including the Southern bluefin tuna Thunnus maccoyii and Pacific orientalis, endemic from Ocean. These specimens were identified within genomic description 10 individuals randomly selected catch to evaluate composition longline fisheries off waters. Most records T. (6), followed by Bigeye...
We propose a novel Bayesian hierarchical structure of state-space surplus production models that accommodate multiple catch per unit effort (CPUE) data various fisheries exploiting the same stock. The advantage this approach in data-limited stock assessment is possibility borrowing strength among different sources to estimate reference points useful for management decisions. model applied thirteen years from seven lebranche mullet (Mugil liza) southern population, distributed along and...
Abstract Temperatures in the southwest South Atlantic Ocean have increased over recent decades due to changes Brazil's Current dynamics affecting marine ecosystems. However, effects of ocean warming on demersal fauna region are poorly understood. Here, we analyse megafauna species composition, and biomass with warm- cold-water affinities for 29,021 commercial catches landed harbours Santa Catarina state, Brazil, between 2000 2019. We find evidence tropicalization Brazilian Meridional Margin...
Abstract Blackfin tuna Thunnus atlanticus often inhabits warm waters of the western Atlantic Ocean from 40°N (Cape Cod, USA) to 22°S (Rio de Janeiro, Brazil). We recorded first catches species in southern Brazil (34°S) and described its new distribution fishing grounds. Since 2007, annual per trip frequency blackfin landings increased for three oceanic fleets Southern Brazil. The spatial higher center gravity records moved poleward. Sea surface temperature anomalies region warmed 1960 2019,...
Abstract Increasing the sink rate of baited hooks by adding weights in close proximity to hook is crucial reduce seabird mortality pelagic longline fisheries. However, placed next are a cause for concern fishing crew because they can fly back event line break, injuring deck crew. Lumo Leads, an alternative weight system designed slide and therefore prevent accidents, were trialled fisheries off southern Brazil. Four trips conducted 26,377 sampled compare rates, bycatch rates catch target...
Abstract In the presente study, cluster analysis was performed to classify 1080 interviews with captains of national pelagic longline fleet (2000 2011), and 38 trips chartered (2003 2008), in relation composition species landed. For 4 groups were identified: 1 - Albacores, 2 Blue shark, 3 Swordfish, Dolphinfish. Albacores. The results indicated that part change their strategies according availability target market demand (internal external). A from Espírito Santo state operates region...
El cangrejo-rojo Chaceon notialis corresponde a una de las tres especies cangrejos profundidad que actualmente se explotan en Brasil. La pesca comenzo el ano 1998 por barcos extranjeros que, desde 2000 fueron intensamente vigilados observadores y rastreados satelites. En 2005 implemento un plan manejo, considerando solamente estudio la dinamica biomasa del recurso, ya conocimiento biologico todavia era limitado. A partir muestras obtenidas bordo los pesca, estimo talla primera madurez machos...
The royal crab Chaceon ramosae is one of the three species deep-sea crabs currently exploited in Brazil. fishery started 2001 with foreign vessels that were extensively monitored by observers and tracked satellite. A management plan implemented 2005 was based only on biomass dynamics, as biological knowledge resource limited at date. Samples taken aboard used to determine size first sexual maturity for males females studying use allometric growth chelae abdomen relation carapace width (CW),...

The incidental mortality of seabirds in longline fisheries is the major cause population declines threatening most albatross and large petrel species (LEWISON; CROWDER, 2003; ANDERSON et al., 2011). Currently there a growing number solutions for reducing seabird on longlines. combination certain mitigation measures can greatly reduce bycatch, although no single measure reliably prevent mortality. night setting, bird scaring lines well-weighted branch are best practice bycatch pelagic (ACAP,...
Endangered sharks and rays usually often lack basic information specific to conservation, such as population size. Previous studies have reconstructed shark ray catch statistics between 1950 2019 for the southeast = south of Brazil, but lacking detail at species level, because catches were grouped by family, genus or even common name (e.g., skates rays, Dasyatidae, Rhinobatos, Sphyrnidae, Squatinidae). In this study, we used proportions from scientific observer fishing trips Dirichlet...
Desde a década de 1990, pesca demersal do Sudeste e Sul Brasil tem se diversificado, incorporando uma ampla gama espécies peixes invertebrados existentes na Margem Meridional Brasileira. O processo ordenamento dessa atividade, por outro lado, manteve-se focado em poucas espécies-alvo nunca evoluiu para acomodar diversificação pescarias. Esse cenário permitiu o desenvolvimento pescaria “multiespécies – multifrotas” submetida pouco controle, que mantido os recursos pressionados suscetíveis à...
In the deep-sea, abundant and diverse biological communities tend to occur in areas where combinations of geological, physical processes locally enhance trophic-wide productivity, sustaining aggregations consumers top predators. These are ‘productivity hotspots’ their delimitation should improve effectiveness area-based strategies designed manage human activities protect deep-sea. We explored premise that fishing operations association with geomorphological features effective surrogates for...
Abstract Age, growth, and maturity of the bluewing searobin Prionotus punctatus were studied to assess its stock status in southern Brazil. Total length compositions, weight, sex, stage recorded from commercial landings, ages estimated transverse sections sagittal otolith. The oldest observed specimen was a 12‐year‐old female. Females grew larger asymptotic ( L ∞ = 384.4 mm) than males 311.7 but at slower instantaneous rate k females 0.41 year −1 , 0.75 ). Reproduction occurred spring early...
