A Field Trial to Study the Effects of Stenella attenuata Deterrent on the Catch of a Light-Falling Net Fishery

Journal of Marine Science and Engineering
The incidental capture (bycatch) of protected cetaceans in fishing gear has become a serious problem worldwide. Bycatch has also had many serious consequences for pantropical spotted dolphins (Stenella attenuata) in the light-falling net fishery within ...

Review of geographical stocks of tropical dolphins (Stenella spp. and Delphinus delphis) in the eastern Pacific [PDF]

, 1985
Information on geographical variation is reviewed for Stenella attenuata, S. longirostris, S. coeruleoalba, and Delphinus delphis in the eastern tropical Pacific, and boundaries for potential management units are proposed.

The larger the cetacean, the more stationary their sleep? Thermoregulatory constraints on the sleep behaviour of captive cetaceans

Journal of Zoology, Volume 327, Issue 4, Page 376-385, December 2025.
Cetaceans face thermal challenges when sleeping underwater. Our study found that smaller body size correlated with more swim sleep and less stationary sleep, while the opposite was true for larger cetaceans. Additionally, bottlenose dolphins increased swim sleep at lower ambient temperatures, suggesting a sleep strategy influenced by body size and ...

Annual estimates of the unobserved incidental kill of pantropical spotted dolphin (Stenella attenuata attenuata) calves in the tuna purse-seine fishery of the eastern tropical Pacific [PDF]

, 2004
We estimated the total number of pantropical spotted dolphin (Stenella attenuata) mothers killed without their calves (“calf deficit”) in all tuna purse-seine sets from 1973– 90 and 1996–2000 in the eastern tropical Pacific.

Characterizing Fraser's Dolphin ( Lagenodelphis hosei ) in the Lesser Antilles: Distribution, Movements, and Co‐Occurrence With Other Cetacean Species to Inform Conservation Strategies in the Caribbean

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Fraser's dolphin ( Lagenodelphis hosei ) is one of the least studied dolphin species due to its tropical, offshore distribution and low density. However, it is frequently observed in the Lesser Antilles, where we characterized its distribution and ecology using 4 years of data collected from Grenada to Anguilla.

Abundance of cetaceans in the oceanic northern Gulf of Mexico from 2003 and 2004 ship surveys [PDF]

, 2007
The Gulf of Mexico (GMx) is a subtropical marginal sea of the western North Atlantic Ocean with a diverse cetacean community. Ship-based, line-transect abundance surveys were conducted in oceanic waters (>200 m deep) of the northern GMx within U.S ...

μCeta: A Set of Cetacean‐Specific Primers for Environmental DNA Metabarcoding With Minimal Amplification of Non‐Target Vertebrates

Environmental DNA, Volume 7, Issue 5, September–October 2025.
Cetacean eDNA metabarcoding results from the aquarium pool samples using new cetacean‐specific primers. μCeta shows superior performance to detect and differentiate different cetacean species. ABSTRACT Biodiversity monitoring is crucial for understanding ecosystem dynamics and species distributions, particularly in the context of anthropogenic impacts ...

Captive dolphins face higher levels of microplastic pollution than wild individuals

Communications Earth & Environment
Traditional research on microplastics in cetaceans has largely overlooked the extraction methods and their occurrence in multi-tissues. Here we present a reliable framework for extracting microplastics from multi-tissues of cetaceans, achieved through ...
