Further Observations and Experiments on Goitre (so Called Thyroid Carcinoma) in Brook Trout (salvelinus Fontinalis)
1. Goitre in fish is a non-infectious, non-contagious, symptomatic manifestation of a fault of nutrition, the exact biochemical nature of which has not been determined. 2. Feeding the highly artificial and incomplete diet of liver is the major etiological factor in bringing about this fault of nutrition which is at once corrected by feeding whole sea fish. 3. Water plays no essential part in th...
متن کاملObservations and Experiments on the So-called Thyroid Carcinoma of Brook Trout (salvelinus Fontinalis) and Its Relation to Ordinary Goitre
Is this thyroid hyperplasia true carcinoma? In view of the facts that young fish are more affected than old fish, that iodin stops the hyperplasia and causes it to return to the colloid state, that removal of the fish from the ponds to the open brook also affects a cure, that the clinical incidence of tumors is directly related to the water supply, and that the severity of the disease as determ...
متن کاملExercise training in skeletal muscle of brook trout (Salvelinus fontinalis).
1. The differentiation of myotomal muscles in the brook trout (Salvelinus fontinalis Mitchill) has been investigated using p-phenylene diamine stained semi-thin sections and cytochemical and quantitative determinations of enzyme activities. 2. Evidence is presented that the range of fibre size in white muscle represents stages in growth rather than distinct fibre types. 3. Electromyography show...
متن کاملObservations on the Etiology of Goitre in Brook Trout
The arrangement and number of the ponds and troughs, the water supply, the strain of brook trout, and their distribution in the ponds and troughs according to age, have remained unchanged since our first observations in 19o9. The crowding has gradually increased during these years, but the general external appearance of cleanliness of the ponds and troughs has not changed. Those containing the ...
متن کاملHave brook trout (Salvelinus fontinalis) displaced bull trout (Salvelinus confluentus) along longitudinal gradients in central Idaho streams?
Invasions of non-native brook trout (Salvelinus fontinalis) have the potential for upstream displacement or elimination of bull trout (Salvelinus confluentus) and other native species already threatened by habitat loss. We summarized the distribution and number of bull trout in samples from 12 streams with and without brook trout in central Idaho and used hierarchical regression analysis to con...
