I have done some reading on previous culture methods and have gained some information.
The eggs seem to require just some flow, I have purchased Iodine for the purpose of keeping bacteria growth down. You use it to do dips.
As far as tanks I am doing doing one system which is kept normal (rectangular) and another which has been altered with Acrylic sheets that are siliconed in. They are curved to allow the system a rounded environment. As the photos show. The rectangular system is divided in the middle will be opened up as the squid get big enough. If I start noticing problems in their behavior then I will slowly start moving them into the rounded out system
I read in one document that hatchlings can be in rectangular aquaria. So I am not to worried. I have seen enough and read things that lead me to believe that this type can be in that type of system. (Side note, O'Shea implied in one of his statements on this site that he had squid in rectangular aquaria before and that had worked, but the expedition he was apart of was on a boat whos motor/motors? vibrated enough to cause a problem with the on board tank/s?) The vibration on the rectangular tank has also been tested and has proven to be very low. So we shall see.
Once hatched they will be grown out and the survivors will be either transferred to the other tank which is set up with curved Acrylic sheets to allow for a rounded environment and a proper current. If they stay healthy in the hatchery tank then the partion that divides that tank will be removed and that will be the home. I am prepared for either scenario. Any extra squid will be given away. Potentially to a local fish store for temporary display as they don't live long.
This particular species, from what I have read, is the best squid for captivity/laboratory cultures.
They can be breed and kept through multiple generations. I do believe their physiology, which is similar to that of a cuttlefish as far as movements go, is a beneficial factor in their success.
