Successful cage rearing young of white-clawed crayfish for reintroduction
Published Online:
Abstract
This is a short presentation to report on the success of a cage suspended in river water, used for the rearing of juvenile and one year old white-clawed crayfish (Austropotamobius pallipes) in the River Lathkill. The cage was developed as part of a reintroduction project (Rogers 2003) and may be useful in other reintroduction projects. It may also be useful to incorporate in the reintroduction protocol (Kemp et al. 2003), which recommends that crayfish of less than 15mm carapace length be not reintroduced. The cage could provide a method of rearing such small crayfish to greater than 15mm whereupon they could be reintroduced. Care would have to be taken with the placing of the cage in donor, recipient or neutral waters if the species of small crayfish could not be determined at first.
