Description
Technical field
The utility model belongs to experimental provision technical field, relates to particularly a kind of easy device of shellfish filtration rate of mensuration.
Background technology
Filtration rate is one of important physical signs of filter-feeding bivalve shellfish, is the basic parameter of bivalve shellfish energetics, can be used for calculating the scope for growth (SFG:Scope for growth) of bivalve shellfish in specific sea area.In addition, filtration rate is also to carry out carrying capacity to assess necessary parameter.Domestic having carried out some research aspect filter-feeding bivalve shellfish filtration rate, compared with international development, in the research of experimental technique, also have a certain distance.Therefore the data that we obtain, need further to carry out in a deep going way in this respect research, so that more can reflect shellfish physiological property.Meanwhile, working out more accurate, simple, easy-operating filtration rate assay method also enjoys popular confidence.
Filtration rate refers to the cumulative volume of unit interval filter-feeding shellfish institute filtered water, is one of important physical signs of shellfish.For many years, although the many research that people carry out the mensuration of filtration rate, due to the difference of assay method, the difference of experiment condition, differs greatly the result of measuring, and is difficult to carry out the comparison between data, even occurs the result that some are conflicting.
Clear filter in France is referred to as hydrostatic method, Fox et al. (1937) and Jorgensen (1943) first Application.This is the current method of comparatively general a kind of indirect determination filtration rate in the world, is placed in container bait concentration in sampling and measuring water at regular intervals by shellfish and seawater and bait.According to the change calculations filter rate clearly (CR) of bait concentration.In the time that shellfish is 100% to the retention rate of bait particle, filter rate clearly equals filtration rate.
CR＝(V/n?t)×l?n(C
