ALEXANDRIA -- Hanson High School students did a little fishing for a hands-on ecology class project Wednesday morning at Lake Hanson.


As a joint project with the South Dakota Department of Game, Fish and Parks, the class netted fish in the lake, located south of Alexandria. They then collected data on what was caught.

It's an ongoing project for the past 20 years, according to Hanson teacher Steve Pociask.

"We do it every spring," Pociask said. "We are getting lengths, numbers and weights for each net."

Five nets were placed in the lake Tuesday and sat overnight to trap fish. The nets are placed in the same location every year.

Wednesday, students retrieved the nets from the lake and analyzed fish that were caught. The fish were counted, weighed and measured. Then, those numbers were compared with previous year's data. Each year's data is sent to the lake association and GF&P.

Northerns, bullheads, bass, catfish and crappies were some of the species that were pulled from the nets this year.

The main reason for the class is to get the students outside for hands-on learning, said Pociask.

"It is kind of a neat project," he said. "Kids get to work with professionals and it keeps their minds engaged and focused, especially this time of year."
