Free-living amoebae infecting freshwater and marine fish include those described thus far as agents of fish diseases, associated with other disease conditions and isolated from organs of asymptomatic fish. This survey is based on information from the literature as well as on our own data on strains isolated from freshwater and marine fish. Evidence is provided for diverse fish-infecting amphizo...

Metazoan parasites can threaten the sustainability and profitability of finfish sea-cage aquaculture. It is critical, therefore, to identify local parasite species and determine which are potentially harmful. Although several studies have documented parasite species on wild and farmed fish from aquaculture sites, few have used qualitative risk analyses to determine the likelihood and consequenc...

The development of the marine aquaculture industry has led to the generation of significant amounts of fish wastes. Marine farm wastes exert adverse effects on the surrounding area of the cages. On the other hand, wastes of fish and other aquatic animals are regarded as major sources of valuable natural bioactive compounds, including enzymes, proteins, bioactive peptides, oil, amino acids, coll...

Six commonly freshwater ornamental fish, namely Poecilia rediculata (guppy); Poecilia sphenops (black molly); Cichlosoma sp. (Cichlidae); Xiphophorus maculatus (platy); Carassius auratus (goldfish) and Symphisodon discus (discus) were examined for parasites during a four years study (19982002) in Turkey. The parasites species found included: Ichthyobodo sp., Ichthyophthirius multifiliis, Chilod...

In several arenas—legislative, academic, corporate, advocacy, and scientific—the welfare of fish has increasingly attracted attention due in part to the expansion of the aquaculture industry, as well as the growing understanding that many handling methods, management systems, and slaughter practices can induce pain and therefore reduce animal welfare. Unlike other animals raised for human consu...

R ay C. Fish (1902–1962) was a leading f igure in Houston’s natural gas industry and a philanthropist. He believed in the American dream of “opportunity for success.” The Ray C. Fish Foundation was established so that others might be encouraged to broaden man’s self-knowledge and to keep the American dream alive. After its founder’s death from heart disease, the Fish Foundation granted $5 milli...
