THE ll-!HJNE RESPONSE OF PlAICE

NMR studies of crab and plaice metallothioneins.

Metallothioneins isolated from the hepatopancreas of the edible crab (Cancer paqurus) and the plaice (Pleuronectes platessa) after cadmium injection are predominantly cadmium proteins containing only small amounts of zinc and traces of copper. The removal of metal ions from the two metallothioneins by EDTA was studied using proton NMR spectroscopy. The rates of removal of cadmium and zinc were ...

Evolutionary impact assessment of the North Sea plaice fishery

There is growing evidence that fishing causes evolution in life-history traits that affect the productivity of fish stocks. Here we explore the impact of fisheries-induced evolution (FIE) on the productivity of North Sea plaice (Pleuronectes platessa) using an ecogenetic, individual-based model by comparing management scenarios with and without an evolutionary response. Under status-quo managem...

Artificial rearing of pigs

I . Baby pigs were removed from the sow 36-48 h after birth and reared on a diet of reconstituted whole-milk powder until 28 d of age. The whole milk was either mildly or severely heated before spray-drying ; the severe heating completely denatured the whey proteins. 2. When the two milks were given at a high level of intake, either at hourly intervals or twice daily, severe scouring and some d...
