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

Trends in Marine Mammal Bycatch in US Fisheries From 1990 to 2017

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 2, February 2025.
ABSTRACT Bycatch is the greatest threat facing marine mammals globally. In the United States (US), there have been significant efforts to reduce marine mammal bycatch in commercial fisheries, particularly through the implementation of the 1994 amendments to the Marine Mammal Protection Act.

Evolution of the vaquita/totoaba socio‐ecological system in the Upper Gulf of California, Mexico

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract The Upper Gulf of California (UGC) hosts a rich marine biodiversity. Complex climatic processes generate high biological productivity enabling the use of resources in a complex socio‐ecological processes (SEPs). Through a literature review, evolution and aggravation of the SEP over 50 years are analyzed.

Genomic Evidence for the Purging of Deleterious Genetic Variation in the Endangered North Atlantic Right Whale

Evolutionary Applications, Volume 17, Issue 12, December 2024.
ABSTRACT The reduced genetic diversity and frequent inbreeding associated with small population size may underpin the accumulation and expression of deleterious mutations (mutation load) in some declining populations. However, demographic perturbations and inbreeding coupled with purifying selection can also purge declining populations of deleterious ...
