| asian fish tapeworm bothriocephalus acheilognathi in the desert southwestern united states. | the asian fish tapeworm bothriocephalus acheilognathi (cestoda: bothriocephalidea) is an introduced fish parasite in the southwestern united states and is often considered a serious threat to native desert fishes. determining the geographic distribution of nonnative fish parasites is important for recovery efforts of native fishes. we examined 1,140 individuals belonging to nine fish species from southwestern u.s. streams and springs between january 2005 and april 2007. the asian fish tapeworm w ... | 2010 | 21413512 |
| elements in fish of malibu creek and malibu lagoon near los angeles, california. | our aim was to assess whether past discharges from a wastewater treatment plant increased metal pollutant loads in stream mobile species in a one-day baseline sampling study that included a coastal wetland. mosquitofish (gambusia affinis) of two sizes, black bullhead (ameiurus melas), and crayfish (pacifastacus leniusculus) were collected from malibu creek, and california killifish (fundulus parvipinnis) of three sizes, as well as arroyo chub (gila orcutti) were sampled from malibu lagoon near l ... | 2003 | 12705915 |
| chlorinated hydrocarbons in pelagic forage fishes and squid of the southern california bight. | large quantities of ddt and polychlorinated biphenyls (pcbs) have been historically discharged to the southern california bight (scb). while these contaminants have bioaccumulated in sediment-associated fishes, little data exist on concentrations of these compounds in pelagic forage species that are the likely food source for larger predatory mammals and birds. the goal of the present study was to assess the extent and magnitude of ddt and pcb bioaccumulation in the four major pelagic species of ... | 2007 | 17941729 |
