First, you should find out what bloodworm are.. you will quickly find out that they are a type of midge larvae. To breed them, you will need small ecosystem.
Daphnia are very easy in comparison, you shouldn't have any problems with those.
i just use frozen food, but i have just bougth a brine shrimp hathcery, which is quite simple, not sure if daphnia are bred/hatched in the same way though.
so far from frozen, but you can make DIY hatcherys, basically a 1litre bottle, salt, brine shrimp eggs (can get off ebay) and an airstone and light, leave for 24-48hrs and suck newly hatched shrimp from the bottom.
If you look on youtube theres a lot of videos of how to make one.
