Fish labelling method is a recognized fish monitoringmethod, has been more than a hundred years of history.By this method, we can understand the rules, fish seasonal migration, the amount of resources, survival / mortality.Conventional external markers provided by our companyinclude T standard, China standard, line / scale, Petersen disk, hard / soft plastic labels etc.. Accept a large amount ofcustomization service.

Advantage

 – cheap price, simple technology, application of fast.

 – are applied widely, meet most of the fish, and other organisms.

 - easy to identify

 - a number, can realize the individual identification

 - apart from the number, can also be printed more information, researchers are reporting to

 - wide application area

 – for statistical analysis and evaluation provide largeenough data

 – longer retention time, the type of course also depends on the marker

Shortcomings

 - rate of return is variable, because they often rely on allfisheries.

 – may cause infection of fish growth, health and survival.

 - labeled biological attachment can be a problem.Increasing the activity of resistance of fish or shellfish, also increased the difficulty of identifying markers.

 - possibly fish are aquatic vegetation or gear stuck.

 - Tag loss rates may be high, depending on the species and is marked on the tag type, fish personnel labeling technique.

 – not suitable for very small fish.

 – may affect the behaviour of fishes (swim / predator /avoidance).
