Krill fishery

Krill fishery is the profitable fishery of krill, small shrimp-like marine animals that live in the oceans world-wide. Estimates for how much krill there is vary wildly, depending on the methodology used. They range from 125–725 million tones of biomass globally. The total global harvest of krill from all fisheries amounts to 150 – 200,000 tones annually, mainly Antarctic krill (Euphausia superb) and North Pacific krill (E. Pacifica).

Krill are rich in protein (40% or more of dry weight) and lipids (about 20% in E. superb). Their exoskeleton amounts to some 2% of dry weight of chitin. They also contain traces of a wide array of hydrolytic enzymes such as proteases, carbohydrates, nucleases and phospholipids, which are intense in the digestive gland in the cephalothoraxes of the krill.

Time server

A time server is a server computer that reads the actual time from a orientation clock and distributes this information to its clients using a computer network. The time server may be a local network time server or an internet time server. The majority important and widely-used protocol for distributing and synchronizing time is the Network Time Protocol, though other less-popular or outdated time protocols continue in use. The time reference used by a time server could be another time server on the network or the Internet, a connected radio clock or an atomic clock. The most common true time source is a GPS or GPS master clock. Time servers are sometimes multi-purpose network servers, dedicated network servers, or dedicated devices. All a dedicated time server does is provide accurate time.
