Spawning of zebra mussels (Dreissena polymorpha) and rearing of veligers under laboratory conditions Spawning of zebra mussels (Dreissena polymorpha) and rearing of veligers under laboratory conditions
The spawning cycle of the zebra mussel, Dreissena polymorpha, is amenable to laboratory manipulations. Techniques are presented that can be used to initiate spawning and rear veligers from fertilized egg to settlement stage. Spawning can be induced in sexually mature mussels by temperature flucuations or by the addition of ripe gametes. Embryonic survival is excellent until the straight...

Techniques for rearing and releasing nonmigratory cranes: Lessons from the Mississippi Sandhill Crane program Techniques for rearing and releasing nonmigratory cranes: Lessons from the Mississippi Sandhill Crane program
Captive-reared Mississippi sandhill cranes (Grus canadensis pulla) reared at the Patuxent Wildlife Research Center (Patuxent) have been released at the Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR) since 1981. Of 131 birds released through December 1990, 103 were reared by foster parents. The remaining 28 were experimentally hand-reared in 1989 and 1990. After refining...
