Rod visual pigment changes in the elver of the eel Anguilla anguilla L. measured by microspectrophotometry
The visual pigments in the retinal rods of elvers ( Anguilla anguilla L.) were examined by microspectrophotometry and high performance liquid chromatography. The glass elver stage had a mixture of rhodopsin P501 1 and porphyropsin P523 2 with the former predominating (P501 1 :P523 2 = c. 60:40). Mor...

Summary: | The visual pigments in the retinal rods of elvers ( Anguilla anguilla L.) were examined by microspectrophotometry and high performance liquid chromatography. The glass elver stage had a mixture of rhodopsin P501 1 and porphyropsin P523 2 with the former predominating (P501 1 :P523 2 = c. 60:40). More mature pigmented elvers had a predominance of the porphyropsin P523 2 (P501 1 :P523 2 = c. 10:90). The shift between the proportions of each pigment was monitored over a 7‐month period and was shown to occur in individual retinal rods. This shift is a reverse of the pigment shift that occurs in adult eels during their downstream migration. |
