Sculpin Myoxocephalus Quadricornis Research Articles

A study of the conversion of cholesterol to bile acids by the use of a fistulated bile duct

A method for the surgical preparation of a bile fistula in the sculpin Myoxocephalus quadricornis is presented. This model was used in demonstrating the conversion of 14C‐cholesterol into bile acids. The main acid metabolite was cholic acid and the presence of dihydroxy bile acids was also demonstrated. The amount of labelled compounds which was recovered in the bile was small both in case of parenteral administration to fistulated sculpins and after peroral administration to intact animals. This may be attributable to slow metabolism at the low ambient temperature these animals require to survive.

Environmentally Determined Variation in the Roe Colour in the Fourhorn Sculpin Myoxocephalus quadricornis (L.)

In Sweden the fourhorn sculpin is present in about twenty relatively deep lakes besides the Baltic. These are situated below the highest postglacial shore-line and have a well developed hypolimnion, where the temperature during the year is practically stable below 30 m.
