Growth variability in individually confined elvers, Anguilla anguilla (L.)
Newly caught elvers Anguilla anguilla (L.) were individually confined, induced to feed and their survival and growth variability compared to those of similar elvers held communally in lowdensity populations. Similar trials were conducted with fast‐growing and slow‐growing older elvers that had been...
