Abstract
A case of massive fish mortality is reported in an aquatic body in the municipality of Izamal in Yucatan, Mexico. The fish analyzed exhibited signs of hemorrhage and suffocation. Analysis of the phytoplankton samples revealed the presence of a flagellated microalga with characteristics consistent with Prymnesium parvum, particularly due to the presence of the haptonema. The average densities of the microalgae were approximately 16 × 106 cells L−1. The documentation of this species in the Yucatán Peninsula and the observed effects represent an emerging risk for the aquatic ecosystems of the region. This risk is linked to the extensive connectivity between aquatic systems in the region, combined with the significant dispersion capability of the species, which is magnified by the increasing eutrophication conditions in these bodies of water.
期刊介绍：
Aquatic Ecology publishes timely, peer-reviewed original papers relating to the ecology of fresh, brackish, estuarine and marine environments. Papers on fundamental and applied novel research in both the field and the laboratory, including descriptive or experimental studies, will be included in the journal. Preference will be given to studies that address timely and current topics and are integrative and critical in approach. We discourage papers that describe presence and abundance of aquatic biota in local habitats as well as papers that are pure systematic.
The journal provides a forum for the aquatic ecologist - limnologist and oceanologist alike- to discuss ecological issues related to processes and structures at different integration levels from individuals to populations, to communities and entire ecosystems.
