Spatial and temporal habitat use by Penaeid shrimp (Decapoda: Penaeidae) in a coastal lagoon of the southwestern Gulf of Mexico
Knowledge of the environmental factors that influence the spatial-temporal densities of penaeid shrimp in Mecoacán Lagoon is important for understanding their relationship with the presence (migration) and estuarine habitat preferences. In the present study, the relationships between the physical-chemical components of water and sediments and the population dynamics of penaeid shrimp in Mecoacán Lagoon were evaluated according to a spatial-temporal and multihabitat approach. In six monitoring sites (Boca, Cerros, Mojarrero, Aspoquero Arrastradero and Pajaral), the density and biomass of shrimp were determined from November 2014 to October 2015 based on monthly captures with two nets (seine and renfro) in three habitats: mangrove, soft substrates without vegetation, and submerged aquatic vegetation that corresponds to seagrasses (seagrasses was registered only in Bocaand Cerros). The maximum salinity was found in Boca (23±2.6PSU), with pH values ranging from 7.9±0.1 to 8.3±0.2, and the maximum dissolved oxygen was found in Cerros (6.6±0.5mg/L). The average texture of sediments was 62±3.5% sand, 24±2.4% silt, and 14±1.2% clay.
