Embodiment 1

[0046] A method for studying the individual growth of the kite squid by using the growth pattern of the inner shell forecarp, comprising the following steps:

[0047] (1) Extraction: Use a scalpel, scissors and other similar tools to carefully extract the inner shell of the squid to prevent the inner shell from breaking and breaking;

[0048] (2) Cleaning: Clean the surface of the inner shell with clean water;

[0049] (3) Preservation: store the cleaned inner shell in a refrigerator at -20°C;

[0050] (4) Soaking: Soak in distilled water for 5 minutes to restore the inner shell to its natural state;

[0051] (5) Staining solution configuration: add 0.1g alizarin red powder into 100ml distilled water to make 0.1% alizarin red dyeing solution;

[0052] (6) Dyeing: the inner shell is placed in 0.1% alizarin solution and soaked for about 24 hours;

[0053] (7) Rinse: Rinse the dyed inner shell sample with running water for about 12 hours, until the inner shell does not flow ou...

Abstract

The invention discloses a method for researching growth of sleeve-fish individuals based on inner shells and front carapaces. The method includes the steps of soaking, dyeing, rinsing, removing water on surfaces, marking, counting growth lines, calculating growth of the individuals and the like. The method for researching growth of the sleeve-fish individuals based on the inner shells and the front carapaces provides a new solution for direct estimation of the sleeve-fish individuals, and has a remarkable value on research and commerce.

Description

technical field [0001] The invention belongs to the field of fisheries, and in particular discloses a method for studying the individual growth of squid fish by using the inner carapace carapace, and relates to the observation and measurement method of the growth pattern of the inner carapace carapace of the squid fish. Background technique [0002] Squid is a general term for molluscs, cephalopods, and guniformes. They are important marine economic species and are widely distributed in oceans and Antarctica in the world. As the key content of squid fishery biology and ecology, growth has been widely concerned by scholars at home and abroad. Otolith is considered to be a reliable material for studying the growth of squid colonies, but it is not suitable for studying the growth of squid individuals. [0003] The length of the inner shell of squid is basically equal to the length of the carcass, and there are relatively obvious growth lines on the surface of the inner shell, ...
