Walter as all my only experience is from my outdoor cultures were as soon as the culture is infected with duckweed, algae or any other aquatic plant the daphnia production is greatly reduced. Also those who collect daphnia from the wild tell me that the best collecting ponds have plenty of greenery around the edge providing fallen leaves to add mulm ect the water is relatively free of aquatic plants. Perhaps its the O2 / Co2 cycle of the plants reducing the amount of oxygen in the water in the relative confines of the 4 or 5 gallon bowls that work best for me. Mulm is important as it is were the resting eggs of the daphnia are deposited to overwinter or to restart the population after the culture has crashed due to lack of food or water fouling.

On a more personal note sorry about the delay to answer the above questions but family matters have been pressing (also why Viviparous pages not updated yet). Back on course soon.

Secondly if the Lady from Canada who contacted me with a view to obtaining some Goodieds to breed can contact me again if she is still on this list. I have lost her e-mail address and do have a contact address for her.
