The mapping swath and along-track resolution can be simultaneously enhanced by using multireceiver synthetic aperture sonar (SAS). Unfortunately, the SAS parameters, including the pulse repetition frequency, SAS moving velocity, and the along-track aperture of the receiver array, are rigorously limited. Any deviation from the strict requirements could result in sampling that is not uniform. Based on the matrix inversion (MI) m...

Biocontrol is a key strategy for disease control, as it is environmentally friendly and widely applicable. This review elaborates on biocontrol in aquaculture, particularly in shrimp culture. Biocontrol in shrimp culture mainly relies on four strategies: (i) direct kill pathogen by Bdellovibrio or bacteriophages; (ii) suppression of intestinal pathogens with probiotics; (iii) reduction of environmental pathogens via probiotics...
