![]() The objective is to highlight how inland fisheries have been changingĪnd the associated challenges for governance and tenure. Key elements of tenure systems, rights and governance issues in the vast, diverse and complex inland fisheries of India are summarized. APIS allows mapping of all uses of the terms in current literature to an APIS score, though some results might differ from current usage. Secondly, it creates an eight level scale, the aquaculture production intensity scale (APIS), that provides three levels of extensive systems, two level of semi-intensive systems and three level of intensive systems. Firstly, it defines extensive, semi-intensive and intensive aquaculture in terms of production functions. The resulting framework accomplishes two things. The terms are then mapped onto the three production function groups. This is done with extensive literature review to find the meaning of the terms. This paper aims to use three kinds of production function groups the input, treatment and output functions to describe and define the terms extensive, semi-intensive and intensive explicitly. The industry has a relatively coordinated understanding of these terms, but an explicit general definition does not seem to exist. For example, 500 N/C is equal to 500 V/m, and 1,000 N/C is equal to 1,000 V/m.Aquaculture intensity has been used for years as a means to gauge how much production a site makes using three terms: extensive, semi-intensive and intensive aquaculture production systems. When F is inserted into the original electric field strength formula, the results are returned as newton per coulomb (N/C), which directly equate to volts per meter. In this case, F again represents force, k equals the coulomb constant, Q refers to the source charge (in coulombs), q is the test charge (in coulombs) and d is the distance between Q and q. The value of F is calculated by using the following formula: In this formula, E represents the electric field strength, F refers to the force exerted by the source charge (in newtons) and q is the test charge (in coulombs). The electric field strength can be represented mathematically with the following formula: This is because electric field strength is specified in terms of linear displacement (per meter) rather than a surface area (per meter squared). distance curve is a direct inverse function and not an inverse square function. In addition, the field strength is inversely proportional to the distance between the source object and the test charge vector point. ![]() The electric field strength at a specific vector point is directly proportional to the electric charge - in coulombs ( C) - of the source object. The test charge makes it possible to measure the electric field strength of the source charge at the vector point where the charge is positioned. This test charge should have a small positive charge that does not interfere with the source charge. To measure the field strength, a test charge positioned at one of the vector points within the electric field of the source object is needed. Each vector point reflects both the magnitude and direction of the electric force at that point. The field strength of the source object can be measured at specific vector points within that field. The field exerts a force on other charged objects in the vicinity, repelling like charges and attracting opposite charges. Electric field strength is also referred to as electric field intensity.Īny electrically charged object produces an electric field. ![]() A field strength of 1 V/m represents a potential difference of 1 V between points separated by 1 meter. The standard unit is the volt per meter ( V/m or V Electric field strength is a quantitative expression of the intensity of an electric field at a particular location. ![]()
