Trout Overview

When it comes to taking care of our fish the first thing you have to consider is their new habitat. If you move a fish to an area that it is incompatible with it, it will die relatively quickly. The first thing you should check for in a new area is water temperature and pH level. You want to make sure the temperature is no higher than 60-65°F, trout like cooler fresh water. Trout like most other fresh water fish like neutral pH levels. A range of 6.5-8.5 is acceptable, but if the water is too acidic or alkaline (basic) will be fatal to the trout. If you have a healthy stream the fish will survive fine, by eating other smaller fish or insects. We use Melick fish food in our ponds to ensure well fed fish. If you would like to purchase the food we use it is available upon request.

Out in the River

Trout can be caught with the traditional and well known rod and reel method. Fly fishing is excellent way to catch trout. There are three main sections of water to look for when you are out in the water. Riffles are shallow, swift moving sections of the river. They are most likely to contain small fish during the morning and evening. Runs are deeper and have a more moderate current. They can hold trout any time of the day if there is sufficient cover. Pools are much deeper and move slower. In this section of the water you should find larger trout trying to rest during the middle of the day.

Some suggested gear for on the water are fishing lines that are stream tested for 4-8 pounds. Salmon roe (eggs), worms, minnows, cut bait, marshmallows, wax worms, corn worms, and stone flies are some good options to use as bait.

Trout Anatomy

Like most fish, colors and patterns vary do to camouflage and mating attractions. The more vivid the colors the closer it is to maturity and is ready to mate. These fish have an adipose fin found right above the tail fin. This fin looks like a small lump. Early hypothesis about the use of this fin was to store fat. This little lump is only found on salmonidae, charcins and catfish. Recent findings in 2012 from Buckland-Nicks and coauthors prove that this fin helps the fish to move 8% faster and more efficient. This lump contains a bundle of sensory nerves. It is now theorized that this fin is a precaudal flow sensory organ. There are two anal fins below the tail fin that aid in stability. They have one caudal fin more commonly referred to as a tail fin. This species tail fin is categorized as a homocercal caudal fin. This means the vertebrae extend a short distance into a symmetric lob of the tail fin. This fins purpose is for propulsion. They have one dorsal fin to prevent the fish from rolling over, as well as turning and stopping. Trout have two pectoral that are right behind their gills. This fins function is for a dynamic lifting force, helping the fish move up and down. Finally they have two pelvic fins that also assist the fish in moving up, down, making sharp turns and also stopping.
