Microinjection of Marine Fish Eggs
2018Microinjection is a powerful tool for studying embryonic development and analyzing gene functions in fish. This technique was first applied to model species of fish such as zebrafish and medaka whose egg chorions could be removed or softened before microinjection.

Overdispersion In Marine Fish Parasites
Journal of Parasitology, 2012A modification of Taylor's Power law was used to compare the degree of overdispersion in frequency distributions from 38 datasets of marine parasites, data that had originally been collected for fish stock discrimination. The results strongly indicate that the overriding factor contributing to overdispersion in these helminths and crustaceans is the ...

Natural hybridization is reproduction (without artificial influence) between two or more species/populations which are distinguishable from each other by heritable characters. Natural hybridizations among marine fishes were highly underappreciated due to limited research effort; it seems that this phenomenon occurs more often than is commonly ...

Forty-seven species of parasites are listed, 46 from the Pacific coast, and 2 from the Caribbean of Costa Rica (one in common between both coasts but in different host fish). Sixteen (34%) were newly described species with speci- mens collected in Costa Rica. Forty species (85%) are worms (38 platyhelminths,

Nature, 1958
IN the course of a comparative investigation of the vitamin contents of different organs from fish1, a rather interesting relative distribution, and in some cases unusually high concentrations, of vitamin B12 were observed. As the importance of vitamin B12 in marine ecology has been emphasized in recent reports2–6, a brief account of the main findings ...

Publisher Summary This chapter describes the culturing of marine teleost fish tissues. Fish are killed by severing the spinal cord just posterior to the head. Scales are removed and the skin is wiped with 70% ethanol. The tissue to be cultured is removed aseptically and consecutively washed for 10-minute periods in three aliquots of modified Hanks ...

Maintaining Healthy Marine Fish
1998At times, disease is a major factor limiting the commercial farming of marine fish, and it can be a source of frustration and disappointment with fish kept for research and ornamental applications.

The study of fish reproduction has grown in importance as global fish populations decline and aquaculture becomes more prominent, two disciplines for which understanding fish reproduction determinants is critical. Spawners and their reproductive strategy are particularly sensitive to changes in environmental factors such as oceanographic conditions ...
