Breed eels in captivity
A study in 2009–2010 at a research facility in Denmark (Tomkiewicz et al. 2012) reported that wild-caught, captive female European eels Anguilla anguilla produced more larvae, which survived for longer, than farmed female eels. Results are not based on tests of statistical significance. Larvae produced in captivity by wild-caught female eels (<100–200,000 larvae/female) survived for 3–20 days after hatching, whereas larvae produced by farmed female eels (6–<100 larvae/female) survived for 1–3 days after hatching. In each of three trials in 2009–2010, eggs were stripped from female eels kept in captivity and treated with hormones. Female eels were wild-caught (11 eels, one trial) or sourced from eel farms (19–62 eels, two trials). Eggs were artificially inseminated with sperm from farmed male eels. Number and survival of hatched larvae were recorded for all female eels that produced larvae (five farmed and six wild-caught).
