Release wild-caught captive-reared eels to re-establish or boost native populations ('head-starting')
A study in 1980–1994 at two lakes in southeast Sweden (Wickström et al. 1996) reported that 2–11% of wild-caught captive-reared European eels Anguilla anguilla were recaptured over 13 years after release. In one of the two lakes (399 ha, 1.5 m deep), 5,959 of 52,945 translocated eels (11%) were recaptured, most of which were migrating silver eels. In the other lake (299 ha, 18 m deep), 619 of 31,134 translocated eels (2%) were recaptured, most of which were yellow eels. In January–February 1980, European glass eels were imported from a French island and captive-reared for seven months before being released in two previously eel-free lakes (124–156 elvers/ha). In 1980–1994, eels were recaptured in mesh traps at the lake outlets and in 3–8 fyke nets (each 10-m long with two traps) at 2–4 sites/lake (frequency of monitoring not reported).
