This fish caught by Brent Hanley near Hanois lighthouse off Guernsey's south-west coast on 15 October 2011 will be submitted as a British angling record. It weighed 1 lb. 14 oz. and 3 drams. The fish had suffered some damage to the second dorsal fin rays during its infancy. Although the ray membrane was intact, five rays were missing. The ratio of the height of the dorsal fin lobe to the length of the pectoral fin keyed out to a Guinean or a greater amberjack, but the gill raker count was too high for these fish. Based on the gill raker count alone, this fish was identified as an Almaco jack, Seriola rivoliana.
Jacks in the genus Seriola are becoming more frequent visitors to the western English Channel. The first Seriola jack captured in Bailiwick of Guernsey records, was landed by George Staples on 7 September 2000 off the east coast of Herm Island. This fish was identified, based on the gill raker count and the fin ratios as a Guinean amberjack, Seriola carpenteri, but some doubt has now been cast on the original identification, and the individual fish, which was destined for the Natural History Museum in London, can no longer be located.
