Some species are halophiles, and can be found in hypersaline lake environments, an example of which is the Makgadikgadi Pan. Uses. Daphnia spp. are a popular live food in tropical and marine fish keeping.
Daphnia populations can be found in a range of water bodies, from huge lakes down to very small temporary pools, such as rock pools (Figures 2.18 and 2.19) and vernal pools (seasonally flooded depressions). Often they are the dominant zooplanktor and form, as such, an essential part of the food web in lakes and ponds.
I have found that lakes/ponds located in limestone-based areas are good sources of Daphnia, but have never found D. hyalina in small lakes/ponds. But no matter where you are in the world, the chances are there is a locally occuring species of daphnid which is as good as any for fish food purposes.
This species of water flea can be found in rocky pools along the Atlantic coastline of the northeastern United States. It is not considered to be widespread in this area, but is regularly found in certain pools in Maine. ... Daphnia, but can cause problems when space and resources are limited.

I have a lot of fun collecting and researching daphnia, and over time have found that it doesn't take a lot of effort or expense. While I have found a good number of technical articles on daphnia, much of what I have learned on an amateur level has come more by experimenting and making mistakes, than from any written material.
Use a turkey baster to feed the daphnia tank green water several times per day. It is said that keeping pond snails in with your daphnia can help produce food for daphnia from the snail's own waste.

Background information on Daphnia Part 1 - Physical description Daphnia, commonly called water fleas, are a freshwater zooplankton found in ponds and lakes all over the world. Daphnia received the name water flea due to their jerky swimming motions.
I found through this study that the Daphnia population increased more in the control and non-polluted pond water than in the polluted pond water (Figure 6) . One of my favorite things about conducting research projects is that you get to meet different people. During the first months of research, I made a visit to the campus of Iowa State ...
