Composición y variabilidad del ictioplancton de la laguna El Quelele, Nayarit, México

Abstract: Resumen.-Se analizó la variación espacio temporal de la abundancia del ictioplancton en la laguna El Quelele, bahía de Banderas, Nayarit. Se realizaron 20 arrastres zooplanctónicos diurnos, estacionalmente de primavera a invierno del 2001. De un total de 20 muestras de zooplancton se obtuvieron 224,4 larvas de peces las cuales estuvieron representadas por seis familias, ocho géneros y seis especies, siendo Engraulis mordax la especie más abundante (68 org. 1000 m -3 ), seguida de Dormitator latifroms (37 org. … Show more

“…There the salinity ranged from 1 to 34.8. Larvae were most abundant in fall and winter, least in spring and summer when it was warm and rainy (Navarro Rodríguez et al 2006). Newly-hatched pro-larvae of D. latifrons (0.8-0.9 mm TL) were found to alternately sink and swim upward in an experimental situation, suggesting that in a flowing system they would move downstream in this fashion, swimming toward the surface and allowing themselves to sink to some depth while being carried downstream, repeating the process till they reached a static water (Todd 1975).…”

“…Es posible que estas diferencias se deban a toda una serie de factores ambientales propios de los sistemas, y principalmente, a las actividades antropogénicas sobre todo a las de infraestructura turística, lo que desfavorece en gran medida a las diferentes especies que utilizan estos cuerpos de agua ya sea como área de refugio, de alimentación, reproducción y crianza, lo que concuerda con diversos autores (Saldierna y Vera, 1993;Núñez-Moreno, 1996;Funes et al, 1998;Miller y Kendal, 2009;Cowan et al, 2013), puesto que las especies marinas fueron las que dominaron en el sistema El Quelele (menos impactado) en tanto que en el estero El Salado (altamente impactado), la especie dominante es principalmente de hábitos estuarinos, a pesar de que ambos cuerpos de agua se localizan en la misma zona climática (semicálida subhúmeda y se encuentran bajo el mismo régimen de mareas. Respecto a los índices de diversidad temporal Navarro-Rodríguez et al, (2006), señalan que en otoño se registró el valor máximo (1.21 bits/ind.) mientras que, en invierno se reportaron los valores mínimos (1.10 bits/ind.…”

“…It is possible that these differences are due to a series of environmental factors from the own systems, and mainly, to anthropogenic activities on the touristic infrastructure, which works against the different species that use these bodies of water, either as shelter, feeding, reproduction or breeding area, which agrees with several authors (Saldierna and Vera, 1993;Núñez-Moreno, 1996;Funes et al, 1998;Miller and Kendal, 2009;Cowan et al, 2013), since marine species dominated the El Quelele system (with less impact), while the estuary El Salado (with higher impact), the dominant species is mainly from of estuary habitats, despite the fact that both bodies of water are located in the same climate zone (semi-warm semi-humid and under the same regime of tides). Regarding the temporal diversity indexes, Navarro-Rodríguez et al, (2006), state that during the fall the maximum value was registered (1.21 bits/ind. )…”
