Kokanee and freshwater sockeye salmon fishing are quickly becoming one of the most popular sought out fisheries in the Pacific Northwest. Kokanee are second only to rainbow trout as the most popular game fish in B.C and Wood Lake continues to provide a great sport fishing opportunity for kokanee. Now with the return of the Columbia-Okanagan River sockeye salmon, there are sport fishing opportunities like no other in the Okanagan.

The popularity of these fisheries can create some challenges however. Some anglers prefer to harvest a limit of the larger sized fish, while releasing the smaller, more abundant kokanee in the process. Others will catch and release fish once their daily limit has been reached in order to continue fishing. This leads to the question: Does releasing kokanee and sockeye increase mortality rates?

91裸聊视频淭丑别 warmer summer months, known as the danger months, are a good time for anglers to strongly consider stopping catch and release kokanee fishing due to increased 尘辞谤迟补濒颈迟测,91裸聊视频� said Okanagan fisheries biologist Jason Webster from Chara Consulting.

As summer water temperatures climb to 21 C, catch and release mortality rates for kokanee and salmon species increases. Kokanee and sockeye commonly move deeper in the water column in July and August, seeking out cooler water temps in the 5 to 10 C range.

滨迟91裸聊视频檚 not uncommon to catch kokanee or sockeye in 60 to 90 feet of water during the summer months. This means a hooked kokanee or sockeye may ascend through a 20-plus degree temperature change in a short period of time which is extremely stressful to the fish and even deadly. Most kokanee simply 诲辞苍91裸聊视频檛 have the energy needed to swim back down to the cold depths in which they came from. Even though the fish may swim away appearing to be unharmed, there is still a chance that it 诲辞别蝉苍91裸聊视频檛 fully recover.

91裸聊视频淭谤辞濒濒颈苍驳 with downriggers can be a very effective method to catch fish on large lakes in summer 尘辞苍迟丑蝉,91裸聊视频� explained Freshwater Fisheries Society of BC scientist Dr. Paul Askey. 91裸聊视频淭丑别 reason why downriggers are so effective is that fish are forced to congregate at specific depths in the water column where they can find temperatures that meet their thermal tolerance limits. However, for this same reason, fish are put under a lot of stress when they are hooked and reeled to the warm surface water. This is not an appropriate method to practice catch-and-release because we expect a high portion of released fish will die. Basically anglers should view summer downrigger trolling as a catch and kill method of 蹿颈蝉丑颈苍驳.91裸聊视频�

Rick Simpson from the BC Wildlife Federation inland fisheries committee added:

91裸聊视频淭丑谤辞耻驳丑 my hands-on experience kokanee and sockeye can easily die when released in high water temperature conditions. 滨迟91裸聊视频檚 better to be safe and keep the fish as part of your daily limit. Let the fish dictate on what size your limit will be for the 诲补测,91裸聊视频� said Simpson.

In the cooler months such as early spring, kokanee are found closer to the surface because the water temperatures are much cooler. At this time, even though 颈迟91裸聊视频檚 not recommended, releasing a kokanee would probably result in a more positive outcome. If an angler chooses to catch and releasekKokanee there are some preventative steps to take to decrease mortality.

91裸聊视频� Use single hooks on lures and bend down the barb for easy release.

91裸聊视频� Minimize the fight time. Tired and stressed fish have higher mortality rates.

91裸聊视频� Minimize handling, which can cause scale loss and later infection. If you must handle a fish, wet your hands first.

91裸聊视频� Use rubber or coated nylon nets which will reduce injury to the 蹿颈蝉丑91裸聊视频檚 slime layer and fins and tangling with hooks.

91裸聊视频� Quickly remove hooks with forceps or needle-nosed pliers. Netted fish can remain submerged in the water while removing hooks. Many fish, especially small ones, can easily be released in the water without netting or handling them.

91裸聊视频� Minimize time exposed to air, especially when the weather is warm. A fish held out of the water is suffocating.

91裸聊视频� Allow netted fish to recover while in the net along the side of the boat (or shore) before releasing.

91裸聊视频� If the fish is bleeding from the gills or was exhausted from the fight, 颈迟91裸聊视频檚 unlikely it will survive after release.
