Changes in fishing production in the northern Brazil [PDF]

Anais da Academia Brasileira de Ciências
This study analyzed temporal changes in fishery production along the northern coast of Brazil to assess evidence of fishing down marine food webs. Landings data from Pará State between 1997 and 2007 were used to evaluate variations in catch composition ...

Mercury (Hg) concentration in fish commercialized in the São Luís fish market (MA) and potential exposure of consumers [PDF]

Anais da Academia Brasileira de Ciências
Fish consumption is the main path of human exposure to Hg and may represent a risk to public health, even with low Hg concentrations in fish, if consumption rates are high.

Blackfin Seabass Utilize Small Estuarine Lagoons as Nurseries: Implications From Juvenile Sampling at Habitat and Seascape Scales

Marine Ecology, Volume 46, Issue 4, July/August 2025.
ABSTRACT Estuarine lagoons provide nursery habitats for marine fishes; however, small lagoons (< 1 km2) have been overlooked. To evaluate the nursery function of small estuarine lagoons (SELs) for temperate marine fish, this study used seining on the coast of the northwestern Pacific (Kyushu, temperate Japan) during the juvenile seasons (winter and ...

An Assessment of the Fish Maw Trade in Singapore and Malaysia Reveals Threatened Species and Highlights the Need for a More Complete Assessment of the Conservation Status of the World's Fishes

Conservation Letters, Volume 18, Issue 3, May/June 2025.
ABSTRACT Fish maw, the dried swim bladder of teleost fish, is consumed throughout much of East and Southeast Asia. The serving of maw is seen as an indicator of wealth, prestige, and status in Chinese culture. While Hong Kong and mainland China are considered major fish maw importers, its trade in these countries remains largely understudied. This lack

Assessing Fish Community Structure and Diversity Across Environmental Gradients in a Tropical Bay

Marine Ecology, Volume 46, Issue 2, March 2025.
ABSTRACT Understanding the relationship between species distribution and the environment across spatial gradients is crucial for biodiversity evaluation. We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities.

Synergies between price and life history enhance extinction risk in open‐access fisheries

Fish and Fisheries, Volume 25, Issue 6, Page 972-984, November 2024.
Abstract There have been few documented extinctions of fished species, but many bioeconomic models predict that open‐access incentives make extinction possible. Open‐access multi‐species fisheries can cause species' extinction if other, faster‐growing species maintain profits at fatal effort levels.

DNA barcoding for the identification of swim bladders: An approach to international trade monitoring

Forensic Science International: Reports
The rapidly expanding global trade in fish maw (dried swim bladders) necessitates urgent forensic monitoring, as this highly processed commodity is morphologically unidentifiable, directly facilitating the illicit inclusion of vulnerable species in the ...

Extraction and characterisation of gelatin from acoupa weakfish skins (Cynoscion acoupa) pretreated with ethylenediaminetetraacetic acid

International Journal of Food Science and Technology
Abstract The growth of the fish production chain in the Amazon region brought large investments, generating jobs and income. However, accompanied by economic growth, there was an increase in the accumulation of organic waste without any management and use.

Species Identification of Totoaba (Totoaba macdonaldi) From Swim Bladders by Real‐Time Fluorescence‐Based Recombinase‐Aided Amplification

Journal of Marine Sciences, Volume 2024, Issue 1, 2024.
The increased illegal fishing to supply swim bladders is the current threat to the Totoaba macdonaldi, due to the high commercial value of swim bladders. Species identification is the foundation of the endangered animal protection. Limited by the sophisticated thermal cycling, specialized machine, and sequencing costs, DNA barcoding might not better ...

Pescada amarela (Cynoscion acoupa) desembarcada: características microbiológicas e qualidade do gelo utilizado na sua conservação

Revista do Instituto Adolfo Lutz, 2012
No presente estudo foram identificadas as características microbiológicas da pescada amarela (Cynoscion acoupa) desembarcada em Cedral/MA e avaliada a qualidade do gelo utilizado na sua conservação. Foram coletadas 42 amostras de pescada e analisadas quanto à pesquisa de Salmonella spp, V.
