Tropical fishes: patterns and propensities
Journal of Fish Biology, 1998When key biological statistics (growth parameters, mortality rates, etc.) of a large number of fish species are plotted against other variables (notably maximum size and mean habitat temperature), clear trends or patterns tend to emerge. These patterns are usually not perceived as requiring explanation, as reflected in the rarity of pertinent ...

Fish zoonoses of the tropics: A Review
Journal of Agriculture, Forestry and the Social Sciences, 2021The possibilities of pathogens transmitting zoonotic diseases to fish or aquatic environments are dependent on seasons, patients’ contact with fish or fish related environment, nutritional habits and the immune system level of the exposed individual.

Lymphocystis disease in imported tropical fish
New Zealand Veterinary Journal, 1981Abstract Lymphocystis disease, affecting snake-skin gouramis (Trichogaster peltoralis) and blue gouramis (T. tricopterus), was diagnosed histologically in 2 shipments of imported tropical fish. Typical virus particles were readily demonstrated by electron microscopy in negatively stained preparations and in sectioned tissues.

Publisher Summary This chapter describes the equations that are commonly used to explain the growth of tropical fishes and presents the range of growth rates and maximum sizes that are achieved. By focusing on tropical fishes, it raises the question as to whether the growth of tropical fishes displays any particular features not shown by fishes from ...

Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences, 1966
Abstract Labroides dimidiatus, a Tropical Wrasse, removes ectoparasites from the bodies, fins, and even the buccal and gill cavities of other fish (figure 1, plate 22). These often show special invitation postures and the ‘cleaner’ occasionally displays in a sort of dance in which the caudal fin is spread and the posterior part of the

Visual pigments of tropical freshwater fishes
Life Sciences, 1967Abstract Data from the analysis of retinae from 55 species of tropical freshwater fishes are not consistent with the classic view of the distribution of visual pigments among vertebrates. Retinene1 pigments were just as common as retinene2 pigments among true freshwater fishes.

Publisher Summary Fishes of the tropical region constitute one of the most fascinating subjects of study in comparative biology. The myriad radiations and adaptive modifications displayed by different groups of tropical fishes cover practically all important phenomena in evolutionary biology.

Tropical fish medicine. Anesthesia in fish.
The Veterinary clinics of North America. Small animal practice, 19881. Before using anesthesia in fish, check water quality parameters for tropical fish aquariums in the locality. 2. Monitor any changes in water quality that result from anesthetic administration, especially pH and alkalinity. Have adequate buffering agents available to counter these changes. 3.
