Problems solved by technology

[0004] Otoliths and horny jaws are considered to be reliable materials for identifying the age of squids. In the past, some studies tried to use the growth lines of the cuticle on the surface of cuttlefish bones to identify the age of squids, but it was difficult to interpret the early growth lines. and cannot be used for age determination

Embodiment

[0041] Embodiment: Utilize cuttlefish bone to identify the method for the age of West African commercial squid

[0042] Such as figure 1 with figure 2 as shown, figure 1 Schematic diagram of cuttlefish bone morphology of West African commercial cuttlefish,

[0043] figure 2 Schematic diagram of splicing of cuttlefish bone growth pattern in West African commercial cuttlefish.

[0044] The operation steps of this embodiment are as follows:

[0045] (1) Extraction: carefully extract the squid inner shell with a scalpel and scissors to prevent the squid bone from breaking and breaking;

[0046] (2) Soaking: Soak with alcohol to remove mucus and impurities on the surface of the squid bone;

[0047] (3) cleaning: clean the cuttlebone surface with hairbrush and clear water;

[0048] (4) Preservation: the cuttlebone after cleaning is stored in a refrigerator at -20°C.

[0049] (5) Drying: take out the cuttlefish bone, and dry the exposed moisture of the cuttlefish bone with ...

Abstract

The invention relates to the field of aquatic science, and particularly relates to a method for identifying the day age of cuttlefish by utilizing cuttlefish bones. The method comprises a method for grinding the longitudinal section of an inner shell and observing and counting growth lines, and comprises the main steps of drying, marking lines, cutting, grinding, polishing, marking points, fixing,counting the growth lines and the like. The invention solves the problems that the inner shell is easy to break during grinding and the growth lines are not easy to observe and count, and provides amethod capable of quickly and accurately grinding to the optimal plane and accurately interpreting the number of the growth lines.

Description

technical field [0001] The invention relates to the field of fisheries, and relates to a method for observing growth lines of cuttlefish bones, in particular to a method for identifying the age of cuttlefish by using cuttlefish bones. Background technique [0002] Sepia is an offshore species, mainly distributed in the offshore waters of various countries, and also distributed in my country. The annual production of this species accounts for about 50% of all inshore cephalopods, and it has become one of the important fishing species in my country's inshore fisheries. As an economically important cephalopod at present, its age, growth, migration, feeding and other basic biology and ecology studies have been paid more and more attention by researchers. [0003] Age and growth are not only important research contents of cephalopod fishery biology and ecology, but also the basis of resource protection and management. Cephalopods have the characteristics of short lifespan, fast...
