Abstract:
... Cryptocaryoniasis is a severe disease of marine cage culture fish, caused by the protozoan Cryptocaryon irritans. However, the sources of C. irritans infection in cage culture farms are still unclear. Previous studies confirmed many cases of biological fouling on the nets of the culture cages. Therefore, we speculate that fouling may be a key infection source of the cryptocaryoniosis outbreaks. Th ...

The study uses both 2018 data from a sample of micro- and small-sized farmers in these States, and the Mexican government’s multidimensional poverty methodology. Results show fewer tilapia farmers in extreme or moderate poverty compared to ...

This study investigated the seasonal population dynamics of ectoparasites infecting captive snubnose pompano (Trachinotus blochii) breeders in marine cages in the Philippines. The pompano breeders were found to be naturally ...

Abstract:
... The hyporheic zone is an important habitat for benthic invertebrates and early‐developmental stages of gravel spawning fish. However, the eutrophication of running waters and, in turn, the excessive periphyton biomass leads to its biological clogging. The result of these processes is oxygen depletion and a reduction in the habitat quality of the hyporheic zone. This study assessed whether top‐down ...
