Hatch Charts: moving water, standing water.

The study of insects can show the condition of the water and what's going to work best to catch a fish. The better condition of a stream, river or lake also means better fishing and larger fish. The health of a stream that hold anadromous fish should be high so that fry can become strong which would yield a high escapement. Stoneflies and Mayflies are the most sensitive to environmental impacts, and human disturbance. Some caddis are sensitive human disturbance and will start to decrease when the stream degrades. A good stream or river would have the below four orders of species in a seine sample taken from a riffle. As a stream degrades the species count will lower, worms and chironomidae will mostly likely be the only specimens, since their abilities to live in sediments. Some Baetis (Blue-Wing Olive) and Caddis will live in these conditions but Stoneflies will be absent. A good example that I see allot is the N.F. Stillguamish and the S.F. Stillguamish. The NF has abundance of Caddis, Baetis, Dipterans, and Crayfish in its higher stretches. Where the SF has nothing from gold basin down, this mainly is because of the slide which create a massive amount of silt.


Mayflies (Ephemeroptera):

Mayflies are strong swimmers that are misunderstood by most fishermen. These little guys are a trouts dersert and a trout will go out of it's way to dine on one. Fly proportion charts are completly wrong for the most part when it comes to duplicated a mayfly. There are four types of mayflies; Crawlers, Clinger, Burrowers and Swimmers, they are each broken into families which I dicuss here. For the most part they look allot alike as adults where size and color sperate them apart. But for the nymphs they are very diffent and have very diffent cahraestic when it comes to habitat and movement. Make sure to study a certian family & genus before trying to imatate it. anonother thing to consider it that location has allot to do with what species some one might be talking about, a March Brown (east coast) and a March Brown (west coast are completly different and that is why learning the latin name will help. After learning the latin names try only to use the latin name when dicussing a pattern so that others know exactly what species is being dicussed. As you will see below there are common names that conflict, this is important to remember. I will only list the most common.

Common; This list has became to large for this intro page please follow this link if you would like to learn more.

Crawlers, Clinger, Burrowers, Swimmers

To view more try going here, or look at the hatch charts I have for Washingtons rivers and lakes.

 


Caddis (Trichoptera):

Caddis are one the most abunant aquatic insect in the world. As most kids are taught that they are periwinkles, this is wrong and should be corrected. There are many types of caddis some build house around thier body made from matter that sorrunds them other are net-makers that build nets under water to trap free living organisms. Some are preditors that are free living. Their name is latan for hair-wing, after the way thier wing appears to made of fibers of hair. They have three major life cycles that are important to fishermen. Larva, Pupa, Adult. Larva is what stage they are in for most of thier life, clinging to rocks and moving around on stream floors. Pupa is the stage where they leave their protection to swim to the suface to hatch, this stage is short but trout feed on this stage selectivly. Adult is after they hatch to fly away and mate, a caddis adult flutering about on the surface is a treat to a trout.

To dispute common name with latan is not as important as with mayflies but one should learn the correct names. most caddis look alike in adult and pupa stage it is thier charsetic that seperate them as larva. I will do my best to explain charastics: continue to caddis page.


Stonelflies(Plecoptera):

These insect are rarely a source of food for trout, they live in fast oxgen rich water.
