Comparison of mosquito control provided by the arroyo chub (Gila orcutti) and the mosquitofish (Gambusia affinis).
Two 6-wk trials were conducted in 28-m2 earthen ponds to compare the efficacy of the arroyo chub, Gila orcutti, to the mosquitofish, Gambusia affinis, as a biological control agent for mosquitoes and a possible replacement for the mosquitofish in sensitive watersheds of southern California. The mosquitofish population growth rate was 1.73 times greater than the arroyo chub population growth rat...
متن کاملEffect of mosquitofish (Gambusia affinis) and sestonic food abundance on the invertebrate community within a constructed treatment wetland
1. The effect of mosquitofish (Gambusia affinis) predation on the invertebrate community in a hypereutrophic constructed treatment wetland in southern California was investigated at two nutrient levels that influenced sestonic food abundance. 2. Gambusia affinis and insect predators in the wetland had a significant impact on larval mosquito density in the wetland irrespective of nutrient level....
متن کاملAn evaluation of the mosquitofish, Gambusia affinis, and the inland silverside, Menidia beryllina, as mosquito control agents in California wild rice fields.
The mosquitofish, Gambusia affinis, and the inland silverside, Menidia beryllina, were evaluated in experimental, one-tenth hectare wild rice plots in Lake County, California, for their impact on densities of Culex tarsalis, Anopheles freeborni and Anopheles franciscanus. Gambusia affinis were tested at 0.6 and 1.7 kg/ha and the silversides at ca. 0.9 kg/ha. The silversides did not survive well...
متن کاملElements 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 pa...
متن کاملDietary composition of Gambusia affinis (Family Poeciliidae) populations in the northern Waikato region of New Zealand
Invertebrates were collected and identified from the stomach contents of eight mosquitofish (Gambusia affinis) populations in the northern Waikato region of New Zealand at 3-month intervals from December 1994 to September 1995. To investigate temporal and spatial patterns in dietary composition a novel analysis programme was created that used Gower's similarity coefficient. The analysis found d...
