High contaminant loads in Lake Apopka mesocosms affect the ovarian transcriptome in largemouth bass [April]

ABSTRACT: Lake Apopka (Fl, USA) experienced heavy uses of organochlorine pesticides (OCPs) in the 1950s-1970 during an intense agricultural period. As a result, the region remains heavily contaminated and was declared a Superfund site by the US Environmental Protection Agency. Aquatic organisms inhabit the freshwater systems in and around Lake Apopka, however the impacts of sub chronic exposure to OCPs in this natural environment are not known. The objectives of this study were to determine the effects of the contamination on the reproductive axis of largemouth bass (LMB) (Micropterus salmoides). In October (2007), healthy LMB were stocked into natural mesocosms and remained in mesocosms before being sampled in January 2008 (at early oogenesis). Additional LMB were placed into mesocosms for 2 mo
