Seine netting is a type of netting used in fish management.
A seine net can be between 10 and 1200 metres in length and looks similar to a standard landing net used by anglers. The netting is weighted at the bottom with counteracting floats at the top resulting in a net wall within the water. It plays a large role in fishery management where its main purpose is the removal of fish from a body of water for stock reduction or survey purposes. Smaller nets can also be used as stops in ponds or raceways.

Occupation distribution of India in various sectors - primary secondary and tertiary?
occupational structure This refers to the aggregate distribution of occupations in society, classified according to skill level, economic function, or social status. The occupational structure is shaped by various factors: the structure of the economy (the relative weight of different industries); technology and bureaucracy (the distribution of technological skills and administrative responsibility); the labour-market (which determines the pay and conditions attached to occupations); and by status and prestige (influenced by occupational closure, life-style, and social values). It is difficult to attach causal primacy to any one of these factors; moreover, their role in shaping the occupational structure changes over time, as society changes. For example, during the early phase of European industrialization, the dominance of manufacturing made for a preponderance of manual occupations, while in recent times the shrinking of this sector, together with the growth in services, has made for an expansion of white-collar occupations. The distinction between manual and non-manual occupations has also become blurred.
The occupational structure is described and analysed by means of various classificatory schemes, which group similar occupations together according to specific criteria such as skill, employment status, or function. Such classifications are also used as a basis for the empirical analysis of economic and social class
