Aroclor 1254

Rainbow trout (Salmo gairdneri) peripheral blood lymphocytes and splenocytes were found to have spontaneous cytotoxic activity against cultured mammalian and fish tumor cell lines. P 815 and YAC 1 target cells were found to be highly sensitive to trout natural killer (NK) cell lysis, while K 562 and ML cells were low and EL 4 was resistant. NK cell activity was not significantly altered by a 12-mo dietary exposure of fish to various concentrations of Aroclor 1254 and/or mirex.

Rostral Pars Distalis

Pituitary glands from 'donor' rainbow trout were transplanted into the anterior eye compartment of 'recipient' fish to examine the nature of hypothalamic control of the follicle cells in salmonid fishes and to explore the possibility of using the eye as a site of pituitary implantation that permits successful recovery of the grafted gland. After 7 weeks the transplanted prolactin cells appeared less active than in in situ glands and some of the follicle cells appeared to be undergoing degenerative processes. This inhibition of prolactin cell activity was thought to be due to the higher osmotic pressure of the ocular fluid.The follicular formation of the prolactin and non-granulated cells was retained in transplanted glands, although the follicle lumina were smaller than in in situ glands and commonly contained cellular debris. This may suggest that the lumina are sites of cellular degradation and possibly stores of precursor substances.

Preferred temperatures of underyearling rainbow trout (Salmo gairdneri) were determined in both vertical and horizontal temperature gradients. No statistically significant difference was found between the preferred temperatures by the two different methods. This suggests that the nature of the gradient plays a lesser role than generally believed in laboratory investigations of temperature preference.
