Naturalized knowledge‐first and the epistemology of groups

open access: yesPhilosophy and Phenomenological Research, Volume 109, Issue 3, Page 856-873, November 2024.

open access: yesAquaculture, Fish and Fisheries, Volume 4, Issue 3, June 2024.
This study investigated the culture suitability of dhela fish in polyculture with carp species in pond aquaculture systems. Results showed that including dhela in polyculture with carp species did not affect total production but significantly increased net profit and benefit–cost ratio compared to systems without dhela. This suggests that incorporating
