Free-swimming fry are as in previous rounds not totally free-swimming.  They are staying tight in the spawning substrate.  Very few evident swimming in open of the tank even as I pulled it out to look.  Then, as I replaced it several dozen came out briefly before swimming quickly back into the substrate.  Previous iterations of early rearing also showed strong association between cover and even first feeding Pirate Perch.  The cover / spawning substrate used this time is much closer to natural root-wads.

 

Freshly hatched BS applied today and the Pirate Perch fry were all about that.

It appears the attraction of the fry to the substrate is based on vision.  The fry do not loiter in the open when displaced by moving substrate.

Evidence for growth is strong.  They are no sticking to substrate like glue swimming vigorously to get back in when dislodged.

Tomorrow is a big day because going to Poplar Bluff to collect 4 male and 8 females to breed in a new and improved setup.  New setup has a 125-gallon aquarium with a much better nesting substrate for egg collection and filming.  Male - Male interactions are what I really want to see.

 

This round a better feed (Otohime) will be used.  Fish will be trained to approach feeder before actual training to eat feed commences.

I left a big gap in this I see.  Fish were collected about 2 weeks after attempt noted above.  Breeding season missed based on condition of fish collected.  

 

Fish have been held in two stock tanks over the summer where natural forages were encouraged and additional pond harvested forage in the form of mosquito larvae and water fleas were applied as supplements.  The Pirate Perch fat as I have ever had them during the warm season.  Temperatures dropping and forages I can get from ponds increasingly markedly.  The fish are not putting weight. They are being exposed to a natural photoperiod and near natural temperature regime.  In about a month they will be given a photoperiod that approximates spring followed by a rise in temperature.
