Did I mention they are free? No cost? Zippo? Well, you have to print them or use them on a screen with your students but these are a really good resource. Check them out.

The Leaf Pack Experiment – A Free Workshop

The Leaf Pack Experiment is a fun, hands-on research and outreach tool for non-scientists which demonstrates how our actions on land impact life in streams and water quality. Leaf Pack promotes inquiry-based interdisciplinary watershed education and engages diverse audiences in conducting their own experiments, gathering relevant ecological data, exploring food webs, learning classification skills, using technology to share data, comparing data with those of other communities and applying that information to protect local watersheds.

Join us at this workshop and you learn how

Art Ideas From A Teacher

Lynn Nichelini teaches at the Santa Margarita Children’s Center in Marin. She found these very cool “little fish” and has shared the source and some ideas of how she uses them in her classroom.

She uses them in a variety of ways including…
– with blue playdough
– to make impressions in clay/playdough
– for sorting/measuring/weighing activities
– stream/lake provocation (blue material for water, wood pieces, rocks) for pretend play
– visual for drawing

Keeping Invaders Out – Wardens and Biologists Make A Great Team

Hatching fish in your classroo helps instill a sense of stewardship within students. They learn to care about their local environments and work to protect and preserve these valuable resources. Some people grow up not caring about the environment or the impact they have on the world.

This article provides an inside look on how law enforcement wardens work to protect California from unscrupulous individuals who sell illegal animals and plants for profit.

Why Are My Eggs Hatching Early?

I have received several inquiries regarding eggs that are hatching seemingly early. A few teachers have reported eggs hatching before they even made it into the fish tank. As sponsor, you may be the first point of contact for teachers.

All in all – we are experiencing a successful year. The eggs are healthy, we are seeing good survival rates, and most of all – students are learning about fish and aquatic habitats. Yes, some classes have to change their release date to accommodate early hatch and fast development.

Here are a few insights:

  • Hatching fish in classrooms is not an exact science – there are some variables we do not control.
  • The water at the source hatchery fluctuates based on weather. The temperature I give you (and which is recorded on the 772 permit) is an average, not a constant. February had some warm days and this may have impacted the development of the eggs.
  • The eggs will develop at different rates both at the source hatchery and in classrooms. The eggs are addled (shocked) at the hatchery when a large percentage of the eggs have “eyed” and again, some will be further along the process and others a bit behind.
  • The eggs we use have undergone a process to sterilize the eggs to keep the fish from being able to reproduce. This is a new process for CDFW and for most fish hatcheries in general. It appears that triploid (sterilized) eggs develop more rapidly than do diploid (fertile) eggs.

Please keep in mind that this is an educational program on what fish need to survive. There are aspects to the process we simply do not control. This alone is a good topic for conversation with students – the fact that humans attempts to control nature have not always worked out as we had originally envisioned. For example, 60 years ago we built dams to store water and protect against floods. To mitigate the loss of habitat, hatcheries were built to make up for lost habitat. Today we find that hatcheries alone are not enough to maintain anadromous fish populations and the old models for having adequate water storage to protect against floods may not be sufficient. More than a century ago we saw burning of fossil fuels as the path to development and progress and now we face issues that may be related to the excessive burning of these fuels.

Interestingly, not all tanks are experiencing this early hatch. There is a bit of variation around the bay area despite the fact that most tanks are running at similar temperatures.

For next year, we will see if we can get eggs that are a couple of days “younger” into classrooms.

If you have questions, please let me know. You are doing a great job and if the eggs hatch early, it is not because you are doing something wrong. Sometimes we are less in control than we like to think we are.

Getting Eggs To Your Classroom

By now, most of you have eggs (or fish) in your classroom. Most of you are fortunate to have a coach who delivers the sweet bundle directly to your classroom. Some of you pick up your package of eggs from a hatchery or other site.

These eggs have made a long and complex journey to reach your classroom – one involving both natural and human made systems. Here a bit of information on what it takes to get these precious eggs into your classroom.

Adult fish are spawned in a hatchery – rainbow trout come from the Mt. Shasta Hatchery in Northern California and the steelhead from the Warm Springs Hatchery in Sonoma County. The eggs are allowed to develop for about 35 days until they develop the eye spot. At this point the eggs are addled to help remove weaker eggs. Rainbow trout eggs are then ready to be transferred from the source hatchery to the Silverado Fisheries Base in Napa. The eggs are then carefully counted, bundled and wrapped, ready for delivery to your classroom.

 

Meanwhile, your application is being processed to ensure only teachers who have completed the required training and have successfully completed the program in the past receive eggs.

Your sponsor picks up the eggs and your permit either from the hatchery or a centralized meeting spot (e.g. Berkeley marina) and the eggs are delivered to your classroom. This is a fun and amazing process to watch as groups of coaches, most of them fly-fishers, meet to collect the exact number of egg packages, match these to your permit, place them carefully in ice chests and zoom off to classrooms all around the greater Bay Area.

It is a large and complex system involving 3 hatcheries, 380 classrooms, 30 sponsor/support organizations, and a gaggle of CDFW staff. Eggs are sent as far as Watsonville, Mendocino County, Lake County, and Tracy – not to mention the 9 Bay Area Counties.

All of this is done because the people behind the scenes believe in you and your ability as a classroom teacher to help students learn the value of quality habitat and how individual actions can impact the survival of wildlife.

The Classroom Aquarium Education Program in the San Francisco Bay Area is the single largest program of its kind in the entire United States. We have enjoyed tremendous environmental successes over the past decades and programs such as this and teachers such as you deserve a fair share of the credit.
