Public aquariums are increasing in popularity. The 19 articles in this section reflect this trend and range from reviews of the roles of aquariums and their future developments, through to the specialized breeding requirements for pelagic jellyfish, Broad-mantle squid and anemone fish. There is a comprehensive review of North American aquariums, plus descriptions of the conservation activities of the Wildlife Conservation Society of New York and the National Aquarium in Baltimore (NAIB). Examples of exhibits with a freshwater theme and a marine environment are given respectively by the aquarium in Chattanooga, USA, and in Grenaa, Denmark. A report is given on the formation of the Fishes and Aquatic Invertebrate Taxon Advisory Group in Great Britain and its co-operation with groups in the USA and continental Europe. A delightful article describes sea slug nudibranchs and their husbandry at Seattle Aquarium, while preliminary data are presented on the possible reproductive biology and culture requirements for cleaner prawns. There are a number of articles on sharks, including a description of the successful Shark Experience in Vallejo, California, a report on the treatment of goitre and a review of husbandry considerations from NAIB. Finally, there are articles on the listing of teleost fish species considered difficult to maintain in captivity, the use of logos to inform the public about possible hazards in keeping certain fish species in home aquariums and the use of ozone to improve water quality in aquatic exhibits.
There are 17 articles in "the developing zoo world" section and the first presents an important overview of the evolving role of modern zoos and aquariums in relation to field conservation with examples where a more holistic approach has been made. This is followed by a report on the conservation activities of Allwetter Zoo, Munster, in Vietnam. The management of Giant tortoises and the breeding and development of such varied species as Savi's pipistrelles, Maned wolves and White-lipped peccaries are described and there is a review of the social parameters which influence breeding in White-faced sakis in captivity. Detailed observations on the suckling behaviour of a Grey seal at Harderwijk Marine Mammal Park, the successful hand-feeding of a Black rhinoceros calf while it was housed with its mother at Dvur Kralove Zoo and the development of feeding behaviours of Giraffe calves at Brookfield Zoo, Chicago, are described. The effects of inbreeding in the captive population of Indian rhinoceroses are discussed, as is the relationship between inbreeding and juvenile mortality in a group of Nile lechwe at Rome Zoo. There are detailed reports on the development of a new exhibit for Tigers and Otters at Melbourne Zoo and modifications to a Gorilla enclosure at Zoo Atlanta and an Asian elephant enclosure at Zurich Zoo. A review on the status of the captive population of Snow leopards well demonstrates the need for captive-breeding programmes. A detailed article from the Zoological Parks Board of New South Wales highlights the advantages of developing local, national and international zoo-based education in the form of formal programmes for schoolchildren, less formal but targeted education of the public and the provision of specialized professional training for zoo workers and wildlife managers in developing countries.
The directory of zoos and aquariums, together with the index and list of regional and national associations comprising 98 pages is followed by a 115-page list of vertebrate species bred in captivity in 1993, a 51 -page census of rare animals in captivity as at 1 January 1994 and an up-to-date list of authorized international studbooks and registers. Cumulative author and subject indexes for Volumes 30-34 complete the volume.
