Several sport fish have bounced back with management. Often sport and commercial fisherman fought the restrictions of the management plan but are glad now that the populations have rebounded.
Redfish (red drum) are very popular in the south and on the gulf coast and actually all the way up to Maine. It was overfished and the population had crashed. Texas declared it a sport fish which stopped commercial fishing and put controls on limits by sport fishermen. Other states put on restrictions as well. Redfish is popular because it is in many places, is good eating and will go after a range of baits and lures, and it puts up a good fight. The population has been making a come back since the restrictions were put in place.
Rockfish / Stripped Bass
Perhaps the most popular sport fish on the East Coast. It is generally called striped bass but is known as rockfish on the Chesapeake Bay. It had been almost wiped out by sport and commercial fisherman. It has been an important fish for a long time. In 1639 one of the first ever environmental laws was passed. Massachusetts declared it illegal to use striped bass for fertilizer.
Because striped bass’ territory covers at least 12 states, regulation would be difficult so the federal government stepped in with some oversight. The law had teeth because if a state didn’t come up with an acceptable plan to protect rockfish, the government could ban all fishing for striped bass in that state.
In Maryland and Virginia, the Chesapeake Bay is the spawning ground for 80-90% of all striped bass on the East Coast. In 1985, the Maryland governor banned all sport and commercial fishing of rockfish in Maryland. A number of other states follow and the ban lasted several years. The fish started to bounce back and a few years back was considered completely restored to historical levels. But in the last few years, the population has dropped some and fishermen have been asked to observe a voluntary fishing limit of one fish per day in a certain size range and none in a smaller size range. It is hoped this gives the 2011 juveniles a chance to get to be breeding stock.
A top predator on the great lakes, the muskie was almost wiped out by the topmost predator of all, man. Over the last 30 years, 5 clubs of anglers have helped bring the muskie back. Each club has a large pond that they fill int the spring. Then food gets tossed in to accelerate algae growth. Then zooplankton start growing and feeding on the algae. At this point, the DNR brings along newly hatched muskie which feed on the zooplankton. More food is dumped in on a weekly basis to sustain the growth of the algae and the zooplankton. The DNR keeps track of their growth and once they reach a certain size it is time to release them. They need to be released because at this size they switch to being carnivores and would start cannibalizing each other. So the ponds are slowly drained and when it is low enough the small muskie are collected and transported to the lake. There are now self sustaining populations in the Great Lakes and rather than continuing to stock those, most of the newly raised muskie are taken to smaller lakes to help those populations bounce back.
So these and others, such as steelhead trout in some areas show that conservation efforts can make a difference.
