Characterization of fish assemblages in a tropical coastal lagoon in the northwest Gulf of Mexico

 Tamiahua is one of the largest estuarine-lagoonal systems in the Mexican Gulf of Mexico. It has great economic and ecological importance due to high fisheries productivity and because it serves as a nursery, feeding and reproduction area for numerous populations of fishes and crustaceans....

description	Tamiahua is one of the largest estuarine-lagoonal systems in the Mexican Gulf of Mexico. It has great economic and ecological importance due to high fisheries productivity and because it serves as a nursery, feeding and reproduction area for numerous populations of fishes and crustaceans. Spatial and temporal variations of fish diversity, abundance, dominant species and community inhabitants were determined based on samples taken on a bimonthly basis from May 1994 to March 1995. A total of 83 species, 62 genera and 32 families were collected, of which 14 species, 8 genera and 3 families were recorded for the first time in this area. Based on our collections and earlier reports, 136 species are known to use this lagoon system at some stage of their life cycle. The highest diversity and abundance values occurred during the rainy season (H'n = 2.7, D = 7.1, and J' = 0.6; biomass = 59.3 g m–2, density = 5.8 ind m–2, and average weight = 10.2 g ind–1). Seasonal fluctuation of these parameters reflects the life cycles of different species (mainly the dominant species) related to the environmental dynamics of the ecosystem. Based on a graph-statistical analysis of the abundance and frequency data of 22,984 individuals, the fish species inhabiting the system were classified into four groups: resident, transient, irregular and rare. This analysis revealed the presence of 9 resident species, representing 77% and 73% of the total number of individuals and biomass, respectively. In order of importance, these species were Anchoa mitchilli, Membras vagrans, Hyporhamphus roberti, Bairdiella chrysoura, Eucinostomus melanopterus, Strongylura notata, Mugil curema, Achirus lineatus, and Cynoscion nebulosus.

Tamiahua es uno de los sistemas lagunares-estuarinos más extensos del Golfo de México. Es de gran importancia económica y ecológica debido a su alta productividad pesquera y constituye un área de crianza, alimentación y reproducción para numerosas poblaciones de peces y crustáceos. Las variaciones espaciales y temporales de la diversidad de peces, abundancia, especies dominantes y componentes comunitarios fueron determinadas de muestras tomadas bimestralmente entre mayo de 1994 y marzo de 1995. De un total de 83 especies, 62 géneros y 32 familias recolectadas, se registraron 14 especies, 8 géneros y 3 familias por primera vez en el área. Basados en esta recolección y trabajos previos, se conoce que 136 especies utilizan el sistema lagunar en alguna etapa de su ciclo de vida. Durante la época de lluvias se presentaron valores altos de diversidad y abundancia (H'n = 2.7, D = 7.1 y J' = 0.6; biomasa = 59.3 g m–2, densidad = 5.8 ind m–2 y peso promedio = 10.2 g ind–1). Las fluctuaciones estacionales de estos parámetros reflejan los ciclos de vida de diferentes especies (principalmente las especies dominantes) relacionados con la dinámica ambiental del sistema. Con base en un análisis gráfico-estadístico utilizando datos de abundancia y frecuencia de 22,984 individuos, se clasificaron las especies que habitan en el sistema como residentes, en tránsito, irregulares y raras. Este análisis reveló la presencia de 9 especies residentes, representando 77% y 73% del número total de individuos y biomasa, respectivamente. En orden de importancia, estas especies fueron Anchoa mitchilli, Membras vagrans, Hyporhamphus roberti, Bairdiella chrysoura, Eucinostomus melanopterus, Strongylura notata, Mugil curema, Achirus lineatus y Cynoscion nebulosus. 2003-03-06 2021-06-03T03:55:03Z 2021-06-03T03:55:03Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/189 10.7773/cm.v29i42.189 https://hdl.handle.net/20.500.12930/7365 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/189/163 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 29 No. 4B (2003); 631-644 Ciencias Marinas; Vol. 29 Núm. 4B (2003); 631-644 2395-9053 0185-3880
