The current dataset contains a record of 40,968 fish larvae belonging to 13 orders, 26 families, and 38 species and related with factors as: depth, habitat type, circadian cycle and season. The objective of this research is to investigate the vertical variability of ichthyoplankton in shallow tropical estuarine zones. The model study site was the estuarine area of the San Pedro y San Pablo River located east of the Centla Wetland Biosphere Reserve in the Gulf of Mexico. The experimental design includes a) depth (bottom-surface), b) habitat type (coast–low complexity and mangrove–high complexity), c) circadian cycle (sunrise-midday-sunset-night), and d) season (dry-rainy).


Steps to reproduce

Sampling was carried out during dry season (May 2018) and rainy season (October 2018). To determine the influence of the circadian cycle on the diversity and abundance of ichthyoplankton, collections were made at sunrise (SR, 5:00 h to 6:00 h), midday (MD, 11:00 h to 12:00 h), sunset (SS, 18:00 h to 19:00 h), and night (NI, 23:00 h to 24:00 h). To analyze the effect of depth, samples were collected simultaneously at 50 cm (surface) and 200 cm (bottom). For each factor (depth, sites, seasons, and day period), three samples were collected (throughout the sampling cycle), each condition was replicated, obtaining a total of 192 samples. To avoid the effect of the tide, all sampling was done during the full moon.
