Who ever said trout don't thrive in south Jersey? One concern some of our teachers with large populations of fish have is a catastrophic loss in the future due to the large biomass in those tanks. I believe that a combination of factors will prevent total loss, although that always remains a possibility in any tank. Cannibalism right now will continue and will lower populations just as it does in nature. Water chemistry issues, seemingly under control in our tanks at the moment, might also cause problems - again due to a large biomass. Teachers and students will find a need to do more frequent water changes as the fish grow in size unless they have a small population already.

Cinamminson H.S. reports somewhere between 60 and 80 surviving fish and all are doing well. Middletown M.S. has 25 fish remaining after "loaning" about a dozen fish a couple of weeks ago to another tank that was in need of fish. Seems like I'm hearing that water quality issues have leveled off and we've gotten through a steep learning curve in that area. Much work will be done this summer to streamline the site to add resources for help with ammonia levels and bacteria colonies so future schools have an easier time with the program. Keep up the great work, all! I'd love to see some of the work that the students are doing in the classroom, email me or feel free to post content at any time.

We still have over 100 fish and they are really growing. I think a few of the larger ones are eating all the small ones. Hi Everyone!!! We still have over 100 fish and they are really growing.

My first year and we've been doing extremely well. We have approximately 50-60 still growing strong. Several of them are about two inches long. In the last coupleof weeks we have an increase in mortality. Mark Ludwig from LV Moore in Roselle.
