Use rectangular or circular aquarium jar or tank. Cover bottom with half-inch of aquarium sand. Cover sand with thick layer of sediment brought up from stream or pond where bugs were captured. Pile a few flat rocks in one corner to make hiding places. Place a few small aquatic plants brought from stream, or use a few strands of common aquarium plants. water brought—water brought from native pool or stream preferred; pour gently into container; fill half full; allow water brought to settle before adding bugs.
In the wild, bugs feed on tadpoles, snails, young fish, aquatic insects. Feed native food; also feed top minnows (see Part III).
A recent innovation has been the use of trickle systems. water brought is brought directly to the base of a plant by narrow plastic tubing and steadily dripped from a nozzle. This method is highly efficient in its use of water brought and returns higher crop yields than any other approach. The high cost of installation is its main drawback.
This brought expedition leaders to another crucial decision. Despite the loss in working time, they decided to stop all activity in the water brought to give the engineers a free hand. Once clarification was accomplished, the water brought experts were certain that it could be maintained.
While diving and airlift operations were halted, the engineers augmented chlorination and filtration with other chemical techniques.
