KIDS: Polk Elementary School Feeding the Fry

{Spotlight Page Header} In the Spotlight
Polk Elementary School - Feeding the Trout Fry
The trout have been moved to the big tank from the egg basket, and are now actively feeding. The students share the feeding and maintenance duties. Care must be taken not to over-feed the fry which could result in uneaten food providing a environment that would encourage the growth of bacteria. Students must carefully monitor the color and clarity of the water, and quickly remove any dead fry. While there have been some losses, most of our fry are health and active.
Many of the trout fry have developed Parr Marks, which are vertical marks on the sides of the fish. They will keep these until their skin is pigmented enough to cover them, usually about one year. Our trout fry are now Parr Fry and they will be in this stage until they are released in the Spring.
