How much water does a fish hatchery use?
- Interestingly, water is a key component in raising fish. On average, the Salmon River Fish Hatchery uses a water flow of approximately 10,000 gallons per minute from wells and a local reservoir. Water temperatures range from 34 to 74 degrees Fahrenheit due to seasonal fluctuations.

just returning hatchery fish. Control the number of hatchery fish on the spawning grounds. For example, trap returning adult fish at a weir, send the appropriate number of natural-origin and hatchery-origin fish on their way and harvest the surplus hatchery fish. As closely as possible, mimic natural rearing conditions in the hatchery.
CDFW's high public use areas, including visitor centers and license counters, are temporarily closed to help slow the spread of COVID-19 (coronavirus). Before heading to a CDFW facility, contact the regional headquarters office to determine if that facility is open.

Fish raised at the Salmon River Hatchery come from a variety of sources. Steelhead, chinook salmon, and coho salmon all develop from eggs taken from wild broodstock that return to the hatchery to spawn. Brown trout raised here are transferred in as fingerlings from other DEC hatcheries. Pacific salmon (Chinook and Coho) and steelhead eggs are placed in special incubators that are supplied with a constant flow of water. The water temperature is what determines the amount of time it takes for the eggs to develop. Shortly after the eggs hatch, the sac fry are transferred into rearing units. At first, these tiny fry are nourished by the yolk sac that protrudes from their abdominal region. After most of the yolk sac has been absorbed, the fry are ready to feed and a dry starter diet is provided. Since dry diets are available in a variety of food sizes, the size can be increased accordingly as the fish continue to grow. The amount of food to be fed each day is also adjusted as necessary t...
Self-guided tours of this accessible facility are available to observe what happens inside a working fish hatchery. There are informational exhibits and mounted fish. Accessible bathrooms are available as well. For current information on the fish and the hatchery call 315-298-5051. There is designated accessible parking at the hatchery entrance.

Due to construction, the Salmon River Fish Hatchery & the grounds (fish ladder, observation decks) remain closed to the public. The Salmon River Fish Hatchery is located on County Route 22, one mile northeast of the Village of Altmar, Oswego County. The Hatchery is open to the public from April 1st (weather permitting - call the hatchery for the spring opening date) to November 30th, 8:30 am to 3:30 pm daily. Tours for organized groups may be arranged in advance by contacting the Inter-regional Environmental Educator at 315-314-0768 or emailing the Salmon River Fish Hatchery. For more information on this and any of the other DEC hatcheries, you may contact the hatchery directly at 2133 County Route 22, Altmar, NY 13302, P:315-298-5051 or contact any of the DEC's regional fisheries offices.

The Current Brainerd Hatchery was established in 1986. Why was it established?To raise walleyes and white suckers. White suckers haven’t been raised since 1996. What is the general technology used for the hatchery?It is a flow through system where water enters the top and cascades down to the bottom and into two holding tanks, going through each hatching jar on its way down. Has the technology been modified since establishment?Major improvements were made in 2009. A telephone alarm system was added as well as a chlorine detector, recirculation abilities, and touch screen controls for temperature regulation. This was done to save money and help the environment by using less water and natural gas. It also eliminated the need for night watchmen. Other improvements have been new hatching jar valves and hoses and the addition of a big screen display for showing walleye production movies during tours. We also started treating all eggs with iodine in 2009. This is to hopefully eliminate an...
In general, fish management tools fall into one of four categories: 1. protecting and restoring habitats and water quality; 2. regulating the harvest; 3. stocking; and 4. public education. Lake surveys and research provide the information used to select appropriate management tools. WALLEYE MANAGEMENT Minnesota has more walleye, walleye lakes, and walleye anglers than any other state. Each year, anglers harvest about 3.5 million walleye. The best way to maintain walleye numbers is to protect critical habitats. Shore land zoning and related laws aid fish by controlling development and protecting spawning sites and aquatic plants that fish use for cover. Stocking is another management tool used. Minnesota’s cool water hatcheries produce 2 - 5 million walleye fingerlings and millions of fry each year. Stocking can provide walleye fishing in lakes that lack spawning habitats but can otherwise support walleye. Stocking is also effective for lakes that have been “rehabilitated” or occasio...
What types of research help with management decisions for this hatchery?We have been tagging fish in the spawning run to see when and if they return. This helps us get an idea of when and how often they come up the river to spawn, how far they travel, and the amount of mortality. This could potentially dictate how many eggs we take to the hatchery. We currently put any extra walleye fry back into the water they originally came from. Studies are also being done to see if these excess numbers actually hurt the lake and we are trying to find the point where stocking should be cut off. This will help us from taking too many eggs. What other factors are involved with management decisions involving this hatchery?We study our lake surveys and assessments to determine where walleye stocking may benefit a lake and where it would be a waste of time. This tells us how many walleyes we will need and in return how many fish to raise in the hatchery. Another factor that we can’t plan for is winte...
