Distribution and ontogeny of digestive enzymes in larval yellowtail and winter flounder

Autor: C. J. Baglole, Glenda M. Wright, Gregory P. Goff

Publikováno v: Journal of Fish Biology. 53:767-784

The distribution of digestive enzymes was studied using histoenzymological methods in yellowtail and winter flounder larvae reared on three different diets: live food, weaned at day 15, or starved. Alkaline phosphatase, dipeptidyl peptidase IV, amino

A comparative histological and histochemical study of the post-gastric alimentary canal from three species of pleuronectid, the Atlantic halibut, the yellowtail flounder and the winter flounder

Autor: Gregory P. Goff, H. M. Murray, Glenda M. Wright

Publikováno v: Journal of Fish Biology. 48:187-206

The histology and mucus histochemistry of the pleuronectid post-gastric alimentary canal was examined using light and electron microscopy. Distinct differences in goblet cell mucus histochemistry were observed between species, with the two closest ta

A study of the posterior esophagus in the winter flounder, Pleuronectes americanus, and the yellowtail flounder, Pleuronectes ferruginea: morphological evidence for pregastric digestion?

Autor: Harry M. Murray, Gregory P. Goff, Glenda M. Wright

Publikováno v: Canadian Journal of Zoology. 72:1191-1198

The morphology and the histochemistry from the mucus of the posterior esophagus of the winter flounder and the yellowtail flounder were examined using light and electron microscopy. The esophageal mucosa of both species was organized into elaborate b

A comparative histological and histochemical study of the stomach from three species of pleuronectid, the Atlantic halibut, Hippoglossus hippoglossus, the yellowtail flounder, Pleuronectes ferruginea, and the winter flounder, Pleuronectes americanus

Autor: Harry M. Murray, Glenda M. Wright, Gregory P. Goff

Publikováno v: Canadian Journal of Zoology. 72:1199-1210

The morphology and the histochemistry of the mucus of the pleuronectid stomach were examined using light and electron microscopy. The stomach of the winter flounder (Pleuronectes americanus) and the yellowtail flounder (Pleuronectes ferruginea) posse

Seasonal Reproduction and Plasma Levels of Sex Steroids and Vitellogenin in Atlantic Halibut (Hippoglossus hippoglossus)

Autor: Birgitta Norberg, David A. Methven, Gregory P. Goff, Laurence W. Crim, Ingvar Huse, Joseph A. Brown

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 49:754-759

Atlantic halibut (Hippoglossus hippoglossus) collected off Newfoundland first mature at about 80 cm fork length (FL) for males and about 115–120 cm FL for females. Captive Newfoundland halibut did not release milt or eggs or have detectable levels

Ontogeny of the digestive tract during larval development of yellowtail flounder: a light microscopic and mucous histochemical study

Autor: Gregory P. Goff, Harry M. Murray, C. J. Baglole, Glenda M. Wright

Publikováno v: Journal of fish biology. 51(1)

The histological development and mucous histochemistry of the alimentary tract in larval yellowtail flounder were studied using light microscopy. Samples were taken when the larvae were first offered food at 3 days post-hatch, then at 7, 10, 29, 36,

Environmental influences on annual variation in nest success of smallmouth bass,Micropterus dolomieui, in Long Point Bay, Lake Erie

Autor: Gregory P. Goff

Publikováno v: Environmental Biology of Fishes. 14:303-307

Successful production of young in smallmouth bass,Micropterus dolomieui, nests varied between 33 and 88 percent over two years. Six variables were measured at each successful smallmouth bass nest. Discriminant analysis indicated that the combined inf

Field studies of the sensory basis of homing and orientation to the home site in Ulvaria subbifurcata (Pisces: Stichaeidae)

Autor: John M. Green, Gregory P. Goff

Publikováno v: Canadian Journal of Zoology. 56:2220-2224

The roles of olfaction and vision in the homing behaviour and orientation to a home site in Ulvaria subbifurcata were investigated. These were examined by studying the home-site fidelity and the homing performance of normal, blind, and anosmic fish a
