Effects of different stocking densities on the CO2 fluxes at water-air interface and the respiration metabolism in sea cucumber Apostichopus japonicus (Selenka)

open access: yesFrontiers in Marine Science, 2022
Recently, abundant research has been devoted to investigating the variations of CO2 concentration in the atmosphere. However, the information of CO2 fluxes at the water-air interface remains limited, especially those from the respiratory metabolism of ...

RESOURCE PRODUCTIVITIES AND PRODUCTION FUNCTIONS [PDF]

open access: yesAustralian Journal of Agricultural Economics, 1957
This paper is mainly intended to provide a vehicle for discussion of recent research in measuring resource productivity using what has come to be known in agricultural economics as the Cobb-Douglas approach. I have attempted to draw together most of the points that have been raised by others together with some comments.

Persistence of Digestive Enzyme Activities of Sea Cucumber (Apostichopus japonicus): Evidence From Diet Switch After Evisceration

open access: yesFrontiers in Marine Science, 2022
A two-stage diet-switch experiment was conducted to examine the hypothesis that the changes in digestive enzyme activities of sea cucumber (Apostichopus japonicus) induced by historic diets might persist in the regenerated intestines.
