4. This transitional period is typically characterized by an emphasis on production volume that precedes the adoption of farm biosecurity, hygiene and management standards. In this context, non-therapeutic antimicrobial use may serve to increase growth and...
utilizing sterilized sea-water (15-35 ppt), usually by autoclave or ultra-violet light, or artificial sea-water made in the lab, usually in closed-loop or in a biosecure, indoor culture room, usually with positive air pressure, and with controlled personnel access, usually with disinfection ...
Then, ten numbers of shrimp were separately transferred to 20 l plastic bucket containing different concentrations of DCTN, P25-TiO2, and DP-TiO2 in 5 l of sterile seawater (30 ppt) at 27 °C. Without any material supplement considered as normal control. The mortality was counted and the ...
concentrations (0-40 ppt) and to be produced in fresh water (Michelotti et al.2018; Liebl et al.2016; Gracia-López et al.2006). Moreover, they are highly prized for the quality of their meat and valued for sport fishing (Passini et al.2019). Processing the fillet is easy, with hi...

The seawater temperature ranged between 14.1 °C and 15.0 °C during the study period with an average salinity was 33 ppt at the surface and 34 ppt at 5 m depth. The pH values were between 7.8 and 8.2 and the dissolved oxygen concentration was in range of 8.1 to 9.0 mg/L. The...
machine (AO LING HENG YE, LA-160, China). 30 and 35 °C groups were achieved by the heater (SUN SUN, AR-450, China). The same feeding protocol was used as described above, and the residual feed was counted daily. The seawater salinity was 25 ppt, and the photoperiod was 14L:10D...
Three salinities, 12, 22, and 32 ppt, were used in a semi-commercial RAS for salmon post-smolt treatment. From the study, sampling was done in the MBBR inlet, outlet, and biofilm. Biofilm communities are higher regarding their Bray–Curtis similarities in comparison between time points. ...
prolifera to hyposaline conditions, from 30 ppt to 10 ppt, has a significant impact on growth rate and photosynthetic performance, decreasing growth rate by 65% [139]. Lu et al. (2006) [129] also found that after only 4 days of exposure of Ulva fasciata to hyposalinity (10 ppt), ...
Water was pumped from Nea Michaniona (Thermaikos Gulf) and freshwater was added to reach 29 ppt salinity. Fresh water was added only to replace evaporation and sludge removal losses. The aquaculture water salinity was between 29 and 31 ppt, and the pH was stable at 8 with minor ...
