Remove or control fish using rotenone
A before-and-after study in 1992 of an artificial pond in woodland in England, UK (McLee & Scaife 1992/1993) found that great crested newts Triturus cristatus and smooth newts Triturus vulgaris colonized following the removal of sticklebacks Gasterosteus aculeatus using rotenone. Larvae of both species were observed in the pond two months after treatment. Released toad tadpoles survived and metamorphosed in the pond. The concrete tank had sloping walls and a water depth of 90 cm. It contained approximately 2,000–3,000 sticklebacks. Rotenone was applied (5%; 0.2 mg/L) in May 1992 and seven days later the pond was dredged to remove dead fish. Over 100 toad tadpoles were then released into the pond. Aquatic plants were also introduced.
