Charter Trips Increased in 2015 Despite Lower Chinook Salmon Catch Rate
According to Michigan DNR Charter Survey Program data, catch rate declined from 7.3 Chinook salmon per charter excursion in 2012 to 2.3 Chinooks per excursion in 2015. Even so, charter captains logged 12,758 trips in Michigan waters of Lake Michigan in 2015 – the highest charter effort recorded since 1991 and a modest increase from 2014.
So why didn't the fishery crash like Lake Huron did when Chinook catch rates dropped in the mid 2000s?
One possible answer is that recession and high gas prices played an important role in the decline of Lake Huron's charter fishery. Another is that Lake Michigan still provides better fishing for Chinook salmon than Lake Huron did in the late 2000s.
The graph above shows the relationship between Chinook salmon catch rate and charter effort. On Lake Huron (blue diamonds) there is a dramatic difference between low-catch rate years and high-catch rate years. Effort on Huron was high in most years when Chinook salmon catch rate was above 2 per trip. On Lake Michigan, catch rate has been above 2 per trip every year since recovery from BKD and charter fishing effort has been remarkably consistent.
Fun Fishing for Freshwater Drum
They are not the most glamorous fish in the Great Lakes, but drum (a.k.a. sheephead) offer some pleasant surprises to open minded anglers. They provide fast fishing for children learning to battle big fish and can even be used in recipes as a substitute for shrimp.

A Mussel Goes Fishing
Many native mussels (Family: Unionidae) use lures to attract fish. These lures are fashioned from the marsupial gills of female mussels, and they contain mussel larvae known as glochidia. When a fish bites the lure, it gets a mouth full of glochidia. The glochidia then live as parasites in the fish's gills for a short time before developing into juvenile mussels.
The Plain Pocketbook (Lampsilis cardium) in this video is using a lure in attempts to to attract a host fish. What does the lure look like? What type of fish might it attract?
