How can I create a good environment for my fish to spawn? | Ponds & Lakes Q&A

Q: How can I create a good environment for my fish to spawn?

Q: How can I create a good environment for my fish to spawn?

Darren – Salyersville, KY

A: A little candlelight, some smooth jazz playing in the background, a private spot beneath the water hyacinth … sounds romantic, doesn’t it? Well, when you’re creating an ideal spawning environment for your game fish, they really need little more than the right set up. The key is knowing what that set up should be – and here’s where to start.

  1. Know Your Fish: Do you know what kinds of fish live in your pond or lake? Before you begin to prepare your fishes’ love nest, you need to know what kinds you have, as different species have different needs. For instance, a spawning Bluegill prefers water temperatures that are 65 to 80 degrees Fahrenheit and some gravel or sand substrate for nest-building purposes. Check with your region’s fisheries and wildlife department for more information about fish common in your area.
  2. Adjust the Environment: Once you know the type of fish you have and their preferred setting for spawning, recreate that environment. In a large lake or pond, you won’t be able to adjust the ambient water temperature, but you can use an aerator to be sure you’re giving the fish enough oxygen, add gravel in the shallow areas and provide hiding spots, like the Porcupine Fish Attractor Spheres, to protect the fish and their young fry. If they feel comfortable, they’ll be more likely to get in the mood for love.
  3. Add Safe Havens: Finally, create some specific areas for spawning fish. Bluegill, for example, will appreciate the Pond King Spawning Discs, which are 20-inch concave poly discs that resemble nests where the fish can deposit their eggs. Artificial habitats, can provide escape areas for smaller fish when placed in water 3 to 4 feet deep. Aids like these also provide a spot for algae – a.k.a. fry food – to flourish.

When you want to set the mood for your finned friends, follow these three simple steps. You’ll create a spawning friendly environment and a lake full of healthy, happy game fish.

How are algae able to grow in the winter when everything else is dormant? | Ponds & Lakes Q&A

Q:How are algae able to grow in the winter when everything else is dormant?

Q: How are algae able to grow in the winter when everything else is dormant?

Patrick – Vandalia, IL

A: Algae can be tough little buggers. An estimated 72,500 algal species exist worldwide, and some of them can thrive in inhospitable conditions, including areas with ice and snow. With a handful of nutrients and a little bit of light, they’re able to grow – even in the 39 degree water under the ice in your lake.

But if your lake’s water is clean and clear during the spring and summer, how can it explode with algae in the winter?

Food Aplenty

Algae feed on byproducts of decomposing organic debris, like phosphorous and nitrogen, in the water. During the warmer months, natural bacteria would typically break down these nutrients, leaving little food for the organisms. But in the cooler months, those bacteria go dormant. That means the algae enjoy a feast – and a population explosion.

If you keep a hole in your lake’s ice, you can help control the nutrient density with a product like Pond Logic® EcoBoost™. This bacteria enhancer, which has no temperature restrictions, binds suspended organics while providing trace minerals to fish. Simply mix it with water and pour it into the lake.

Let There Be Light

Algae also require sunlight to thrive – but not much. Even through a clear, solid sheet of ice, algae can get enough light to use for photosynthesis. When that light is impeded, however, the algae won’t grow as quickly.

A layer of thick snow cover is Mother Nature’s way of preventing light from penetrating the water, but you can also use pond dye, to block those rays. The blue or black dye comes water soluble packets that are simple to use: Just toss two packets per acre into the lake, and the shade will inhibit algae growth.

Algae’s Benefits

Believe it or not, algae growth in the winter does have its benefits. It helps to filter the water, and on warmer days it’s a great snack for your fish. Plus, when the algae photosynthesize, they give off oxygen as a byproduct – which is then available for your fish (and other aquatic critters) to breathe.

Don’t worry: The algae won’t take over your pond like it does in the summer. It can grow, but the cold temperatures aren’t ideal for explosive outbreaks. If you’re concerned, however, try some EcoBoost and Pond Dye. They’re safe for your fish, and they’ll keep that algae under control until spring.

Mike – Little Rock, AR

A: Yes, those little freshwater crustaceans can indeed live in your pond – as long as you provide the living conditions they need to thrive. Here’s what you need to know about growing a healthy crayfish population.

Home Sweet Home

Also known as crawdads and crawfish, North American crayfish belong to the family Cambaridae. More than 300 species live in rivers, brooks, ponds and even special “crayfish farms” across the country. Most types prefer fresh flowing water that doesn’t freeze in the winter, but some thrive in swamps and ditches.

During the day, crayfish hunker down underneath rocks to hide from predators like fish, birds and alligators. But at night, they slowly cruise the river bottom in search of food. Their preferred meals are anything decaying, including dead insects, worms, algae and fish, but they’ll also snap up small, live fish that are swimming by if they’re feeling too lazy to forage. They’ll also get their greens by gobbling through algae and aquatic plants.

These decapod crustaceans can grow up to 6 inches in length. They’re related to lobsters, crabs and shrimps, and they’re prized cuisine among foodies (etouffees anyone?) and larger fish, like bass and bluegill. Crayfish and dwarf crayfish are also kept as colorful pets in aquariums.

Welcome Residents

Crayfish can make a fun addition to your pond. They nibble on aquatic plants, so they help control weed growth. They eat decaying material, so they – along with Pond Logic® MuckAway™ – will help keep pond muck to a minimum. They’ll entertain your son (and his friends) for hours as they turn over rocks and hunt for crayfish. And they make for some delicious eating for you and your resident fish!

These guys will dig to create burrows in the bottom of your pond – but don’t worry. They won’t likely cause any leaks. It’s important, though, to control their population. Crayfish reproduction is tied to fluctuating water levels, so manage their population growth by stabilizing the water level in your pond, and use basket traps or lift nets baited with meat to remove large numbers.

Create a comfortable environment for crayfish by providing clean, aerated water and some rocks for burrowing. They’ll find their own food – or become food if they venture too close to your Fish Attractor Spheres!

A: Surface area and pond depth are important measurements to know. They’ll help you determine dosage rates with chemicals like algaecide. They’ll help you calculate the right-size aeration system for your pond. And they’ll help you figure out how many and what types of fish to stock.

Finding those magic numbers isn’t difficult – but it does require some tools, the right equation and a little bit of work. Before you head out to your pond, grab a rope marked at 1-foot increments, a weight that’s heavy enough to sink to the bottom, and something for notetaking.

Calculating Surface Area

The easiest ponds to measure are those that resemble a rectangle, but you can figure out the surface area of a circular, triangular or odd-shaped pond, too. First, you’ll need to measure (with your marked rope) or pace off (one step is about 3 feet) some specific distances, depending on the shape of your pond. Then, plug those numbers into one of these formulas:

  • Square/rectangle: Calculate length and width; L x W = Surface Area
  • Circle: Calculate radius; Pi x R2 , or 3.14 x R x R = Surface Area
  • Triangle: Calculate base and height; (0.5 x B) x H = Surface Area
  • Odd-shaped: Use a handy online tool like Bing Maps to measure the pond. Online tools may be easiest, especially for irregularly shaped ponds.

To determine how many acres your pond is, you’ll then divide that surface area figure by 43,560 (one acre).

Calculating Depth

Figuring out your pond’s depth is a bit trickier, particularly if you have plant shelves or if the pond has a slope. Grab your marked string, the weight, something to write with, and a boat or canoe. Then, head out to the pond and follow these directions:

  1. Securely attach the weight to one end of your string.
  2. Climb aboard your boat or canoe with your weighted string and note-taking materials in hand.
  3. Travel to at least five points in various areas your pond, more if your pond is particularly large.
  4. Drop the weight into the water and note where you feel it hit the bottom. Repeat until you’ve gone to all the different spots and gathered a good sampling of your pond’s depth.

Why They’re Important

Now that you know your pond’s size, why are those calculations important?

You’ll need the numbers to determine dosage rates on chemical products like those found in Pond Logic® ClearPAC® PLUS. If the pond has been around more than three to five years, chances are good that you’ll need to address problems like muck accumulation and string algae growth in the spring.

Those numbers will also help you select the right-size Aquastream™ Fountain and Airmax® Aeration System. For instance, if your pond is less than 6 feet deep, our Shallow Water Series™ Aeration System is a good choice; if your pond is greater than 6 feet deep, our Pond Series™ Aeration System is the one for you.

Since you’ll be able to calculate how many acres your pond is, you’ll also be able to determine what types of fish you can have and how many of them you can keep. Finally, because you’ll know the various depths of your pond, you’ll be able to stake out safe swimming areas for children – but don’t forget to put out your life ring!

Setting Pond Resolutions for 2015

If you were one of the many pond owners plagued by algae, muck, excessive weeds or green water last year one of your 2015 New Year resolutions may revolve around your pond or water garden.

Evaluate

The beginning of the new pond season is the perfect time to evaluate and tweak your pond maintenance practices and take inventory of leftover pond supplies from last year. Since pond maintenance begins once the ice thaws from your pond, there is no better time to start planning for the upcoming season than now.

First, before you buy new pond maintenance products, recall your pond issues from last season. Were you continuously fighting algae? Unsure the last time you applied your beneficial bacteria? Do you have out of control cattail growth? After you identify your issues, pick one or two items to tackle in 2015.

One great product for any pond (earth bottom pond or water garden) is aeration. Aeration is always a great way to keep your pond water balanced and healthy. Installing an aeration system in your pond will circulate the entire water column and keep oxygen plentiful. Aeration systems help reduce pond muck formation and weed growth while keeping your fish safe and comfortable.

If your pond receives constant sunlight, consider shading the water with pond dye. To keep your pond water clear and remove accumulated pond muck treat your pond with beneficial bacteria. Airmax® can help you eliminate the guesswork when choosing the appropriate pond maintenance products by providing the most effective pond care products in one kit. Use the ClearPAC® to treat earth bottom ponds and lakes or the DefensePAC® for water gardens.

Make a Plan

Next, make a plan. Check over any unused pond products from last season. Create a list of any supplies you are low on or anything you are out of. If you are having trouble calculating how much product you will need for season long treatment or have any questions on a particular product you can always call a Pond Guy or Gal toll free at 866-766-3435.

If you don’t have a pond, water garden or water feature yet you can start researching and designing the pond of your dreams now. There is a wide variety of information available on our blog that explain the differences between various water features and ponds. Pond kits are available for purchases that contain all of the items you need to build a water garden. If you prefer something less time consuming, maybe you would like to consider a pondless waterfall. Whichever the case early planning will help make your pond project a success.

Can Aquatic Weeds Go Dormant? | Ponds & Lakes Q&A

Q:Will my fountain be enough to keep my fish safe this winter?

Q: Can Aquatic Weeds Go Dormant?

Jackie – Kalamazoo, MI

A: Yes, those insidious aquatic weeds can go dormant in the cold season, lying in wait in your lake’s muck and sediment, until spring when the hours of sunlight and temperatures increase. The good news is that you can battle them – even in their overwintering state. Here’s how.

Growth Patterns

When temperatures drop and the sun hovers lower in the sky, you’ll start to see those aquatic weeds retreat and hole up for the winter. The duration of their dormancy will depend on where you live (the weed growth patterns in a California pond, for instance, will differ from those in a Minnesota pond!). But, in general, you can expect to see different pond weeds disappear and reappear at different times of year based on environmental temperatures.

If your pond or lake freezes over, the perennial weeds will typically die back in the winter and re-emerge in the spring. Some plants, however, will continue to grow throughout the cold season, though at a much slower rate than you’d see in the warmer summer months.

Controlling Winter Weeds

Because you’ll probably see little to no greenery growing, it will be a challenge to control winter weeds. Methods that work in the spring and summer – like treating with temperature-sensitive herbicides and algaecides – won’t work in the colder temperatures. So what can you do? Here’s what we recommend:

  • Remove Weeds: If there’s no ice on your pond, you can pull on your hip waders and manually remove the weeds with a Weed Raker. This go-to tool efficiently pulls out aquatic weeds by their roots, slowing their regrowth, and also removes decaying matter.
  • Pond Dye: Pond Dye, available in convenient liquid quarts, will shade the water blue or black and reduce the amount of sunlight reaching the weeds and algae growing at the bottom of your lake. Less sunlight means fewer weeds, regardless of the temperature or time of year.
  • Aerate the Water: If you’re not using your lake as an ice rink, crank on your Airmax® Aeration System. The action created by the aerator will circulate the water and reduce the muck buildup throughout the winter.
  • Feeding Fish: Your fish will enter into a semi-dormant state when the water dips below 50 degrees, so there’s no need to feed them. Doing so will add to the lake’s nutrient load (i.e. weed fertilizer …), which is not what you want to do.

If wintertime weeds are taking over your pond, consider trying some of these time-tested tricks. They’ll minimize the nuisance growth during the cold season and reduce the amount of work you’ll need to do in the spring.
