Collective term for the particulate material suspended within the water column. Seston includes particulate organic matter such as plankton and organic detritus as well as inorganic particles such as silt. (Anonymous (1998) AQUALEX.

Acoustic models are models that use analytical and numerical scattering models, for example to to predict acoustic backscatter from aquatic organisms. (Adapted from https://asa.scitation.org/doi/10.1121/1.4937607)
Entrainment is the unwanted passage of fish through a water intake, which is generally caused by an absent or inadequate screen surrounding the water intake. (https://dep.wv.gov/oil-and-gas/Water%20Management/Documents/Entrainment%20and%20Impingement%20Prevention%20BMPs_Final.pdf)
Note
Intaking of free-floating organisms from surrounding waters through power plant screens.

This condition can be found in carcasses of cattle or sheep and sometimes pigs and turkeys soon after slaughter. The carcass meat is darker and drier than normal and has a much firmer texture. The muscle glycogen has been used up during the period of handling, transport and pre-slaughter and as a result, after slaughter, there is little lactic acid production, which results in DFD meat. This meat is of inferior quality as the less pronounced taste and the dark colour is less acceptable to the consumer and has a shorter shelf life due to the abnormally high pH-value of the meat (6.4-6.8). DFD meat means that the carcass was from an animal that was stressed, injured or diseased before being slaughtered. (FAO, 2001. Guidelines for Humane Handling, Transport and Slaughter of Livestock, RAP Publication 2001/4)
