The first full week of no trap netting on Gloucester Pool in search of muskies for an egg collection is now behind us and crews from Midhurst and Aurora went back to their busy routines with other field and office work.\u00a0 Both Blue Jay Creek and Fleming Hatchery staff remained very busy as well doing their utmost to ensure each precious egg and newly hatched fry was getting the best care possible. Thankfully those big muskie-to-be, have the most dedicated hatchery staff imaginable to ensure their well-being.\u00a0 In this week\u2019s update we are fortunate to have two good week-ending reports \u2013 supplied from Paul Vieira at Blue Jay and Mark Newell, at Fleming.<\/p>\n

Blue Jay Creek::<\/strong><\/p>\n

Egg survival was poor maybe due to the late spawning?<\/p>\n

All of the Musky have hatched and fish are living off of their yolk sacs, feeding will start soon. They look like Balsam Fir needles.<\/p>\n

Presently we have 40 fry from the Pointe Au Baril family<\/p>\n

1200 fry from G Pool family<\/p>\n

 <\/p>\n

Paul M still has feelers out with our lake unit colleges in case they come across any ripe fish, it is pretty late in the game though.<\/p>\n

Fleming College:<\/strong><\/p>\n

Similar story here\u2026 right down to the balsam fir needles! I\u2019ve used that comparison many times over the years!<\/p>\n

We are expecting swim up to begin at any time. The battle of feeding strategies is on repeat in my brain as I try to figure out how to maximize success of the few fry we do have. Current count is around 1575 but there are maybe 5% of those that are really borderline\u2026 alive but bent, stunted or otherwise challenged. So call it 1500 quality looking fry.<\/p>\n

\u00a0I wouldn\u2019t wish this scenario on anyone, it is going to be a tough go!<\/p><\/blockquote>\n

Bent Muskellunge fry. This pic taken 1st week of June shortly after hatch.\u00a0 It shows some of the severely challenged fry removed by the hatchery staff.\u00a0 There was a higher than usual proportion of these in this particular family. <\/strong><\/p>\n

\u00a0\u2026 warm temp at collection or old donor fish (senescence)? Combination?<\/strong><\/p>\n

 <\/p>\n

Fathead Minnow Fry:<\/strong><\/p>\n

These tiny almost transparent newly hatched Fatheads can be great food for baby muskies!\u00a0 However once they have a taste of these will they ever accept manufactured diet? Unlikely! <\/strong><\/p>\n

However, Mark Newell from Fleming is preparing for all eventualities saying <\/strong><\/p>\n

\u201cIt may come to the point where we may HAVE to feed the young muskie these fatheads so we are scrambling right now to figure out how to optimize our production, harvest and sorting of these young fry\u201d.<\/em><\/strong><\/p>","protected":false},"excerpt":{"rendered":"
