The Atlantic bonito (Sarda, family Scombridae) is a pelagic species and one of the most exploited small tuna species. Despite its economic importance, biological information is scarce with no associated management directives. In this study, using a population genomic approach resulted in a lack of panmixia of two genetic pools with different effective population sizes (east central-tropical Atlantic and northeast Atlantic-Mediterranean) and an intermixing zone in Atlantic Morocco.

- Captive-bred animals, including non-native brown trout, are often released to boost populations but risk harming native genetic diversity due to hybridization.
- The eastern Pyrenees management agency has established "genetic refuges" to protect native brown trout by banning hatchery releases while maintaining pre-existing fishing regulations.
- Effective management requires addressing scientific, cultural, and political challenges, gaining support from anglers, and monitoring both native and introgressed populations to balance conservation and human use.
