adspersus, to Cadmium. IV. Effects on the Immune 

 System. By Richard A. Robohm and Maureen F. 

 Nitkowski. October 1974, p. 15-20, 1 fig., 1 table. 



ABSTRACT 



Two elements of the immune .system in ounners. Tautogolabrus 

 adspersus, were examined after 96 h exposure to cadmium; 1) 

 clearance of intracardially injected bacteria from the bloodstream 

 and 21 ability to produce antibody against intraperitoneally injected 

 sheep red blood cells (SRBC). Exposure to 12 ppm cadmium 

 increased the rates of bacterial uptake in phagocytes of the liver and 

 spleen but significantly decreased the rates of bacterial kiUing 

 within these cells. Exposure of fish at 3 to 24 ppm cadmium failed to 

 influence antibody production against SRBC. These re.sults indicate 

 that cadmium affects one aspect of cellular immunity but not 

 humoral immunity in cunners. This effect may increase susceptibil- 

 ity to infection.

ABSTRACT 



In the liver of cunner, Tautogolabrus adspersus. exposed to 3 

 ppm and to 24 ppm Cd for 96 h. aspartate aminotransferase activity 

 was 71% and 59%, respectively, of the activity in Hvers of control 

 fish. 



In the livers of cunners exposed to 24 ppm Cd. nictinamide 

 adenine dinucleotide reductase activity required 20 mM Mg for 

 activation of the same order that 2 rnM Mg produced in control 

 livers. 



Although individual variation precludes generalization here, 

 what may be a metal complexing group of proteins in the serum of 

 cadmium exposed cunner warrants further electrophoretic study.

 W. Newman and Sharon A. MacLean. October 1974, p. 

 27-33. 8 figs., 1 table. 



ABSTRACT 



The histopathological effects of acute exposure of cunner. 

 Tautogolabrus adspersus, to water containing cadmium chloride 

 were manifested in the kidney, intestine, hemopoietic tissue. 

 epidermis, and gill. Few significant changes were noted in fish 

 exposed to concentrations le.ss than 48 ppm for 96 h. The results 

 implicate renal failure as the probable cause of death after acute 

 exposure to cadmium. 



682. Heat Exchange Between Ocean and Atmosphere in the 

 Eastern North Pacific for 1961-71. By N. E. Clark, L. 

 Eber, R. M. Laurs, J. A. Renner, and J. F. T. Saur. 

 December 1974, iii -i- 108 p., 2 figs., 1 table, 5 plates. 



ABSTRACT 



Summaries of large scale heat exchange between ocean and 

 atmosphere in the eastern North I'acific Ocean are presented for the 

 period 1961 through 1971. The summaries are based on computa 

 tions made from synoptic marine radio weather reports and include 

 1) monthly values of total heat exchange and departures from a 

 long-term mean; 2) long term monthly mean values of the total heat 

 excnange. incoming solar radiation, effective back radiation, and 

 evaporative and sensible heat transfer; and 31 annual cycles of total 

 heat exchange for selected areas. 



Outstanding spatial and temporal features of the heat exchange 

 values are discussed. However, little detail is given since this is a 

 summary report, and the readers can draw their own conclusions 

 depending upon the intended use of the charts. 



Comparisons are also made between the total heat exchange 

 values and those given in two other reports. Discrepancies between 

 values given in this report and those published in the other reports 

 are attributed to differences in empirical equations u.sed to make the 

 heat exchange computations, differences in data processing 

 techniques, differences in the observed data used in the 



computations due to different methods of acquisition, and the 

 possibility of ocean climate changes.

ABFL-3. Salmon Fry Production in a Gravel Incubator 

 Hatchery, Auke Creek, Alaska, 1971-72. By Jack E. 

 Bailey and Sidney G. Taylor. November 1974, iv + 13 p., 

 12 figs., 6 tables. 



ABSTRACT 



Survival and physical characteristics of pink salmon fry, 

 (hicorhynchus gorbuscha, incubated in two types of boxes, each box 

 containing about Im^ of gravel, and a Health incubator were 

 compared with fry from natural spawning to evaluate the use of 

 boxes to product fry. The gravel incubators were seeded at 

 densities of 74.200 to 198.000 eyed eggs/m '. Survival from eyed 

 eggs to emergent fry ranged from 79 to 97% in artificial incubation, 

 but the number of incubators tested was too small to define any 

 relationships between survival and incubator type or egg density. 

 With artificial incubation in gravel, survival from potential eggs in 

 females to emergent fry was 69%, whereas with natural spawning 

 and incubation in the creek, survival was about 12%. 



Fry emerged from gravel incubators about 3 days earher than 

 from the streambed. The gravel incubator fry were larger than tray 

 fry but smaller than creek fry. The smaller size of the gravel 

 incubator fry could not be explained entirely on the basis of early 

 emergence. 



Further studies were recommended to determine whether the 

 muskeg sediment that accumulated in the incubators, the low 

 oxygen level (57 to 69% saturation), or the substrate particle size 

 and composition inhibited growth of the embryos.
