Who doesn’t love salmon? Not only is it delicious, but it’s also incredibly healthy for you! This fish is relatively easy to farm. All you need is a pond built to the right specifications, and soon you’ll have a fresh supply of salmon right in your backyard. To help you get started, we’ve answered some of the most common questions about raising salmon in ponds.
Steps
Is it possible to raise salmon yourself?
Yes! You can absolutely raise salmon on your own. In fact, raising fish at home is quite similar to growing vegetables in a garden. All you need to do is create a suitable environment, introduce the salmon, and feed them. Once the fish reach full size, you can harvest them whenever you like.
- Just like garden vegetables require care and maintenance, you will need to regularly monitor and care for the salmon raised in your pond.
Can salmon be raised in freshwater?
Yes, you can raise salmon in freshwater with a closed-loop system. Wild salmon generally live in saltwater, but once a year, they swim into freshwater to spawn. However, salmon can also be farmed in tanks or specially designed freshwater systems that prevent the fish from escaping and protect them from sea lice, which often affect wild-caught salmon confined by nets.
- There have been significant advancements in freshwater salmon farming, including the development of fish feed, which reduces the reliance on wild fish to feed the farmed salmon.
- Selecting strong, healthy broodstock helps ensure a good salmon breed for freshwater environments.
How would you build a salmon pond in your backyard?
Dig the pond in a naturally low-lying area where water tends to collect. Look for a spot in your yard where rainwater often pools after heavy showers to find a low area. Sketch the desired size and shape of your pond. You can dig it with a shovel, hire someone to do it, or rent an excavator to dig the pond, making sure that the depth of the pond is 2.5 to 3 meters to give the salmon cooler water when they need it.
- No matter the pond’s size, the general rule is that there should be a deep area at least 2.5 meters deep, covering 5-10% of the pond’s surface to ensure the fish have enough space and oxygen.
- If you lack experience digging, consider hiring a contractor with the right tools and machinery.
- Before you begin digging, contact local utility companies to make sure there are no underground power lines in your yard. If you're in the United States, you can call 811 for this information.
Place mortar-mixed sand, geotextile fabric, or pond liner fabric at the bottom of the pond. Mortar-mixed sand is a fine concrete sand that helps create a smooth surface for the pond liner. Spread an even layer of sand over the entire pond floor. Then, lay down a layer of geotextile fabric over the sand. Finally, you’ll place a layer of pond liner fabric (a rubber material that helps the pond hold water) on top of the geotextile fabric. The combination of sand, geotextile fabric, and pond liner will prevent water loss and create a smooth surface at the pond's bottom for the fish.
- The geotextile fabric will protect the rubber liner.
- Press and smooth the pond liner as flat as possible. Water will help keep the liner in place.
Do I need to test the water quality in the pond?
Yes, it's essential to maintain a balanced pH level. Checking water quality is quite simple. Choose a basic at-home water test kit, collect a water sample, and use the color code to read the results. The ideal pH level should be close to 7. If adjustments are needed, you can use one of many commercial products available to balance the pH in the water.
- Salmon may not survive if the pond water's pH is too high or too low.
- If you prefer natural products, you can use crushed coral to raise the pH or root wood or limestone to lower the pH.
Do you need to oxygenate the pond water for the fish?
Yes, you need at least one method to provide oxygen to the pond water. Fish species that live in flowing waters, such as salmon, require high oxygen levels dissolved in the water. Consider installing a fountain or artificial waterfall to create flow, or use another structure that generates oxygen before the water flows into the pond. You can also use pipes or a dam to direct the water flow into the pond and help oxygenate the water.
How do I introduce the fish into the pond?
Introduce the salmon into the pond along with the water when purchasing the fish. You can buy either young salmon or fully grown salmon from hatcheries or order them online. When you purchase or order the salmon, they will be placed in plastic bags or containers filled with water. Place the container in the pond to allow the water temperature to match the pond's, then release the salmon into the pond along with the water from the container so the fish can adjust to their new environment.
- Soak the container in the water for 15 to 30 minutes to acclimate the temperature.
- While you can introduce salmon eggs into the pond and hope for them to hatch, starting with either young or adult salmon is much easier.
How should you feed the salmon in the pond?
Feed them quality salmon feed regularly, but avoid overfeeding. High-quality salmon food will provide the necessary nutrients for the fish raised in the pond. Check the feeding instructions on the packaging to determine how much to feed based on the number of fish. Be careful not to overfeed, as this can lead to bacterial or fungal issues.
How long will it take to raise salmon?
It will take about 2 years for the salmon to reach full size. The time from raising to harvesting the salmon depends on the age of the fish when they are introduced to the pond. If they are freshly hatched from eggs, it will take about 2 years for them to reach maturity. However, if you start with already grown fish, you can harvest them whenever you like!
- After about 2 years, pond-raised salmon will typically reach a length of about 50 cm.
Tôi có thể duy trì cá hồi nuôi trong ao bằng cách nào?
Để cho cá hồi sinh sản và tránh thu hoạch quá mức. Miễn là bạn không thu hoạch toàn bộ cá hồi trong ao, chúng sẽ đẻ trứng, sinh sản và tạo thêm lứa cá hồi mới! Hãy chăm sóc cá, cho ăn đều đặn và chỉ bắt cá lên khi bạn định ăn cá, và ao cá của bạn sẽ là nguồn cung cấp cá tươi bền vững!
Lời khuyên
- Thường xuyên kiểm tra độ pH của nước. Bất cứ sự thay đổi đột ngột nào cũng có thể dẫn đến tình trạng cá chết.
Cảnh báo
- Many regions have laws or regulations regarding the practice of raising fish in private ponds. Be sure to thoroughly check the local laws to avoid any violations.
