US Fish and Wildlife Service
A member of the US Fish and Wildlife Service survey crew lies beside the gigantic 108.8kg lake sturgeon pulled from the Detroit River.
Jason Fischer was shocked at what his crew had just caught.
Fischer, a US biologist who works with a Michigan-based Fish and Wildlife Service office, was on the water late last month, putting out setlines with hooks to catch and survey the lake sturgeon population in the Detroit River. It was his first setline survey with this three-person crew, and until then, his research had focused on egg and larval stages – "we're talking about a fish less than an inch".
