How good is this natural control on sea-lice?

, : How good is this natural control on sea-lice?. Fish Farmer 13(3): 44...46

The potential for wrasse (Labridae) to act as biological control agents of copepod (Caligus elongatus and Lepeophtheirus salmonis) and isopod (Gnathidae and Cymothoidae) parasites of farmed salmon (Salmo salar) is discussed. Wrasse have shown promise in commercial-scale trials in Norway and the Shetlands and goldsinny and rockcook wrasse (Ctenolabrus rupestris and C. exoletus) have been shown to be particularly effective "cleaners" of parasitized fish.

An inexpensive, low maintenance light-trap was developed for use in determining the distribution and abundance of marine larvae in regions where conventional methods may not be used. The light trap was a portable system (0.021 msuperscript 3 total...
