What is the sensitivity of fish?

Thus, two-color interphase FISH provides a sensitive method for analyzing chromosome fusion events without the need for a prior cell culture. Another research application of interphase FISH makes use of chromosome-specific paints to obtain information about the organization of chromosomes within the nucleus.

The ide has a higher number of scales along its lateral line (55–61), a rounder body, and a bigger mouth and head.

    How are the fish weights calculated?

    The fish weights are calculated with the formulas below. If a fish girth is not specified, the default value Fish Girth = 0.58 * Length is used. Fish Weight = Length * Girth * Girth / 900.

    What is the default value for fish girth?

    If a fish girth is not specified, the default value Fish Girth = 0.58 × Length is used. You can also calculate the weight of tarpon and other saltwater fish .

    How much surface area do I need for my fish?

    The calculator reflects this by providing two extremes. For slender fish, we use the value of 12 square inches of surface per length-inch of fish (or 30 sq cm/1 cm of fish) For full-bodied fish, we use the value of 20 square inches per inch (50 sq cm/1 cm) of fish. Cold water tanks and marine tanks have higher surface requirements.

    Can back-calculations be used to estimate the size of fish?

    Indeed, back-calculations can be (Campana 1990). Un fortunately, this is n ot the case for the MF model where estimates of fish size “a” at otolith fo rmation are required. This pa rameter will always be very usually form just prior to hatching. For ex am ple, average values of body length at of 0.96, 0.97 a nd 0.98, re spectively.
