Fisheries Management and Ecology, Volume 32, Issue 6, Page 499-515, December 2025.ABSTRACT Fishing tourism of sailfish and accompanying species represents a significant source of income for Costa Rica. However, little information is available regarding trends in the availability of these species to recreational fleets. We estimated temporal trends in catch per unit effort (CPUE) for sailfish, marlins, yellowfin tuna, and mahi mahi ...

Fastest Fish Shapes and Optimal Supercavitating and Hypersonic Bodies of Revolution
Innovative Biosystems and Bioengineering, 2020 Background. The best swimmers have a streamlined shape that provides a flow pattern without boundary layer separation and delays the laminar-to-turbulent transition. Their shape itself could be the reason of small drag and high locomotion velocity.

Ecography, Volume 2025, Issue 11, November 2025.Global change will impact the distribution and abundance of predators through a combination of abiotic variables, such as temperature; and biotic variables, such as prey availability. However, there is a poor understanding of how distribution projections with biotic variables differ from those with abiotic variables, particularly in resource‐limited ...

From reels to research: Motivations and concerns of billfish citizen science participants
People and Nature, Volume 7, Issue 11, Page 2956-2970, November 2025.Abstract Citizen science facilitates cost‐effective ecological data collection at much larger scales than would otherwise be feasible. This is particularly useful for the study of highly migratory species with broad distributions, such as billfishes.
