摘要:
Five interspecific and 18 intergeneric sunfish crosses were attempted by artificial stripping and fertilization techniques. Hatching success appeared to be related to phylogenetic relationship. In interspecific crosses, hatching success was 64–122% as high as in the parental control cross. In intergeneric crosses it varied from less than 1 to 104% as high as the parental cross, but in only 5 of the 18 intergeneric crosses was hatching success more than 60% as great as in the control cross.

摘要:
The chromosomes of sea-run Atlantic Salmon from three North American rivers were studied with cell culture preparations. Extensive data from Machias River (Maine) specimens showed a sharp mode of 54 chromosomes. Modes of 55 for the Narraguagus River (Maine) and 56 for the Miramichi River (New Brunswick) represented much smaller percentages of their counts. A relatively constant arm number of 72 indicates a Robertsonian pattern of polymorphism.

摘要:
Chinook salmon (Oncorhynchus tshawytscha) eggs and alevins were exposed continuously to low levels of gamma radiation from a60Co source, from the instant of fertilization until the yolk sac was completely absorbed. The irradiated fish were compared with a similar stock that was not exposed to irradiation. The level of irradiation exposure was gradually increased from 0.5 roentgen/day for the 1960 brood year, to 1.3 roentgens/day in 1965, 2.8 roentgens/day in 1966, 5.0 roentgens/day in 1967 and to 10.0 roentgens/day, a total of 820 roentgens, for the 1968 brood year.

摘要:
It appears that nature has experimented extensively with various modes of gene duplication in fish. We witness extreme diversity in the genome size as well as in the degree of gene duplication among fish. There are those that have increased their genome size exclusively by repeated tandem duplication of chromosomal segments. They show no proportional increase in the number of functional gene loci. In this group, the trend for progressive elimination of excessive genetic redundancy appears to have started in modern times.
