Missouri Lifts Restrictions on Otter Trapping

For the first time in recent history, the state of Missouri has lifted harvest level restrictions on the river otter, marking a high point in one of the most successful conservation stories in the United States.

Just a few decades ago, Missouri’s otter population was considered almost nonexistent, with only an estimated few dozen otters left in isolated locations.  The plight of the otter in the state was probably due to a combination of over-trapping and shooting.  You see, otters were once a very valuable furbearer, and they eat lots of fish, which doesn’t sit well with many anglers and commercial fishing interests.

While unregulated trapping surely played a part in the otter decline, it was trappers who helped restore a species that now numbers over 15,000 individuals.  Otters were captured from neighboring Louisiana, using the same conventional methods that recreational trappers use to catch the critters for their fur.  They were then transferred to Missouri and released in suitable habitats.

Beginning in the early 1980’s, Missouri transplanted 845 otters into 43 different streams.  With strict regulations in place to limit harvest, otter populations began to grow exponentially.

The years of otter transplants and limited harvest paid off, and a healthy population of otters exists throughout the state.  The success of the otter project may have been too great, however and the species, according to the experts, may be exceeding healthy (and socially acceptable) levels.

Like with many animals, an overpopulation of otters can mean increased spreading of disease, starvation, and a depletion of the food base.  Many Missourians are concerned that otters are having an impact on fish populations in small ponds and large rivers alike.  The Missouri Department of Conservation receives numerous ‘problem otter’ calls, and has documented fishery declines in high-density otter areas.

Fortunately, the Department has the ability to manage otter populations at a healthy and publicly acceptable level by allowing limited otter harvest during trapping seasons.

The first otter trapping season opened in 1996, and has expanded over the years to encourage increased otter harvest.  Still, harvest levels haven’t been high enough to meet management objectives.  Otter fur prices are much lower than they were historically, and trappers are few and far between compared to days of yesteryear.  So there haven’t been enough trappers out in the woods to harvest otters in high enough numbers to keep their populations in check.

Which brings us to today, where Missouri has decided to lift the harvest level restriction on otters, allowing each trapper to take an unlimited number of otters.  The DOC will continue to monitor harvest levels and make future regulation changes if otter populations decline or grow to unhealthy levels.

The Missouri model is similar to how many U.S. states are managing their furbearer populations.  It’s this level of sophisticated wildlife management what will ensure both healthy furbearer populations and regulated trapping continue for generations to come.
