    Description / Table of Contents: Summary 1. The continuing increase in demand for shrimps and prawns in the world markets, at a time when the basic understanding of the biology and ecology of Penaeid shrimps permits a more precise definition of the parameters of their culture, has provoked enlightened support of research and a considerable investment in field evaluation by several industry and government agents in the United States in an effort to establish a viable cultural enterprise. 2. Reproduction biology, spawning and larviculture, are reviewed here as they apply to the production of postlarvae ofPenaeus duorarum, P. setiferus, andP. aztecus. Intensive culture in high-density postlarvae-stocked ponds, and extensive culture by postlarval seeding of natural embayments are compared and evaluated. 3. Management practices as exercised in the maintenance of high productivity conditions in the ponds, and embayments; feeding with appropriately formulated rations; and harvesting techniques are discussed for both cultural systems. 4. Potential growth rates, product yields and production costs can now be postulated, and the economic return on investment from a commercial venture can now be estimated.
    Notes: Kurzfassung Der zunehmende Bedarf an Garnelen für Speisezwecke hat in den USA zu beträchtlichen Investitionen geführt mit dem Ziel, rentable Verfahren für eine umfangreiche Zucht von Penaeiden zu entwickeln. Als erfolgreich hat sich die Züchtung von den im Golf von Mexiko auftretendenPeneus duorarum, P. setiferus undP. aztecus erwiesen, deren Fortpflanzungsbiologie und Larvenkultur beschrieben wird. Die Möglichkeiten für eine Intensivkultur der Decapodite dieser Arten in Teichen und deren Aufzucht bis zum adulten Stadium in abgeschlossenen Meeresbuchten werden unter Berücksichtigung der Futteransprüche und Fangmethoden diskutiert.

    Notes: Abstract Seasonal changes in gonald size and stages of gametogenesis in the black abalone Haliotis cracheroidii were related to changes in environmental parameters. H. cracheroidii showed an annual reproductive cycle terminating in a synchronized spawning in late summer. Gametogenesis was initiated immediately after spawning. Gametes were present in the gonad through the winter months. Gametogenesis was initiated a second time in the spring months. Maximal gonad growth (to a gonad index of 20%) occurred during summer months prior to spawning. Changes in gonad size andperiods of initiation of gametogenesis revealed no apparent correlation with changes in seasonal water temperature. Changes in gonad size showed no apparent relation to change in day length. Total polysaccharide levels in foot tissue changed seasonally, indicating that food availability is probably not a factor in directly regulating gonad growth. Gonad index data for the chiton Katharina tunicata (collected over a 10 year period) showed no apparent correlation to seasonal change in water temperature.

    Notes: Abstract A procedure is described for the preparation of 90 g batches of NiS. Molten NiS has been shown to exert a pressure of about 9 atm of sulphur and to be compatible with liquid B2O3. Near single crystals of NiS(h) have been grown by the high pressure liquid encapsulated Czochralski technique. Evidence suggests that the as-grown crystals exhibit variable stoichiometry and an annealing procedure which gives apparently homogeneous samples is described.
