Gyotaku Fish Print Activity for Kids

Today we are going to continue with our ocean science-themed activities for kids, with a fish printing activity based on the Japanese art form, gyotaku.

Gyotaku is wonderful because it incorporates both art and science into a combined learning experience. While making colorful prints, children observe the fish closely. In the process they learn about fish external anatomy, and also details useful in identification of individual species. See this index for an extensive list of examples of gyotaku fish prints by artist Joe McAuliffe.

Gyotaku started in Japan as a way for fishermen to record their catch. Traditionally, gyotaku prints were made by applying inks to an actual fish and then pressing thin, but tough paper onto it. Today you can buy rubber or plastic replicas to use for printing. You can print on paper or cloth as you choose. The fish example above is printed on cloth.

You will need:

  • Fish or fish model
  • Block printing inks
  • Cloth or paper
  • Plates or trays for holding the ink
  • Brayer (hand roller for loading and applying ink)
  • Newspapers, old tablecloths or sheets to cover printing surface
  • Fish external anatomy illustrations, such as at South Carolina Department of Natural Resources.

The process is relatively simple, but may require practice to achieve the desired results. If you are using actual fish, you will need to wash it with water to remove mucous/debris from the surface. Dry the fish. Place some block printing ink into the plates or trays, and ink up the brayer by rolling it through the ink. Apply the ink evenly to the fish. Now you may either press the paper onto the fish or press the fish onto the paper, as evenly as possible. Play around with the technique to see which way works best for you and how much ink is needed. Set the paper or cloth aside and allow to dry.

Traditionally not much else is added to the print, but you can use your imagination. This gyataku print includes seaweed.

There are loads of places to learn more about gyotaku on the Internet, just load up your favorite search engine and go.

Where to get supplies:

Acorn Naturalists sells a number of gyotaku supplies.

 

Models to use for printing are also available on Amazon (photo is affiliate link).

Sea Horses and Other Fish

Our family finally made it to the beach and had a lot of fun. We visited the Monterey Bay Aquarium and saw the “Secret Life of Sea Horses” exhibit. It was awesome, take a peek (the aquarium was packed, so excuse the noise):

What kind of creatures are sea horses? Are they fish? They have an exterior that looks rather hard, so some people might wonder if they are crustaceans. The tiny fins and gills give it away though, sea horses are fish! If you replay the video, look for the tiny gills and fins moving.

Sea horses and their relatives, the pipefish and seadragons, are called gasterosteiform fish because they lack scales and have bony plates instead. They are poor swimmers and often rely on camouflage to hide from predators. The seadragons in particular have so many leafy flaps on their bodies they look like floating seaweed instead of animals.

Sea horses are carnivores and eat small crustaceans, such as tiny shrimp and planktonic invertebrates.

This pretty silly video from National geographic gives more fun facts.

Activities:

1. Gyotaku and fish anatomy

Are you familiar with the Japanese art of gyotaku, making prints or rubbings from fish?

Traditionally, prints were made by applying paint to actual fish. Today you can buy rubber or plastic replicas, including those for sea horses. You can print on paper or cloth as you choose. This particular fish is printed on cloth.

Our instructions for making gyotaku (previous post).

2. Moving Through the Water.

Different fish have different shaped bodies. Do some move through the water more easily than others?

Check the CDAS website or the Catalina Island Marine institute for an introduction to fish body types.

Gather:

  • modeling clay
  • string or yarn
  • scissors
  • sink with water

Cut a few pieces of string about 18 inches long (at least two). Form a few golf ball-sized lumps, the same number as pieces of string. Take a small lump of clay and wrap around one end of the string, so the string is embedded. Form the lump into a rough sea horse shape (perpendicular to string).

Now take another ball of clay and wrap around another piece of string. Form this into a typical fish “tube” shape wrapping around the string.

This shape is called fusiform.

Put each shape into the sink and drag across the water. Does one shape move more easily than others?

Try some other fish shapes as well. Which shape moves through the water most easily?

Now it is time to finish our summer beach science series and get ready for fall. We’ll miss the sand between our toes (although I think I still have some in my hair), but look forward to a brisk change of pace and some autumn foliage.
