Growth and alkaline digestive proteases activity of Parachromis dovii larvae fed live prey and formulated diets with different protein sources
(Universidad Técnica de Manabí (Ecuador), 2022-07-16)Parachromis dovii is a carnivorous cichlid fish from Central America, which easily accepts formulated feeds since exogenous feeding starts; however, its larval growth is lower than that obtained using live food. For this ... -

(Universidad Nacional (Costa Rica), 2023-06-01)The objective of this study was to determine the larvicidal activity against A. aegypti of ethanolic extracts of plants commonly found in Costa Rica. [Methodology] Larvicidal activity of ethanolic extracts of plants was ... -
Population genetics and biophysical modeling inform metapopulation connectivity of the Caribbean king crab Maguimithrax spinosissimus
(Inter-Research Science Center (Alemania), 2019)Marine organisms with a short pelagic larval duration (PLD) are assumed to display significant population structure given low long-distance dispersal ability. For the wider Caribbean, theoretical and empirical considerations ...
