Abstract
The distribution and abundance of larvae of the genus Solenocera and adults of Solenocera vioscai (Burkenroad, 1934) were analysed. Factors affecting their distribution and abundance in Campeche Sound are discussed. We found the occurrence of a period of higher reproductive activity related with the time of maximal primary production during summer, that is, the rainy season when the supply of organic material is greater. A larval dispersion model related to the pattern of predominating water currents in each climatic period is given. During summer, larvae concentrate in front of the Terminos Lagoon, due to the presence of a middle-scale cyclonic gyre. During autumn, larvae are transported to the central region of the study area in front of the Grijalva-Usumacinta system and the Boca de Puerto Real at the outer shelf. Finally, in spring, an anticyclonic current is observed (in southwestern direction), which transports the larvae and tends to concentrate them in front of the coast of Tabasco.
