After collection total length (mm) was measured for each fish and lapilli
otoliths were extracted.
Therefore, this study was conducted to evaluate the relationship between
otolith weight and observed age (calculated by reading annuli on sectioned
otoliths) in the stocks of S.
Ages determined from the use of
otoliths and scales collected from river herring were compared to quantify aging bias and precision.
Life-history transects were collected across the
otoliths perpendicular to growth rings to generate time series.
In the present study, we carried out a morphometric comparison (body and
otoliths) of the Pacific thread herring O.
This happens when the small calcium particles called
otoliths that are attached to the inner ear fibres within the fluid of the inner ear canals move out of their space.
The keys to Llopiz's research are tiny calcium carbonate stones, called
otoliths, that grow from birth in fishes' heads.
Characteristics of annual rings on scales,
otoliths, vertebrae, opercular bones and cleithra of two loaches, Misgurnus anguillicaudatus and Paramisgurnus dabryanus collected from Zhengzhou city, Henan Province, China, and the precision of age estimations from the five different structures of these two loaches were investigated in this study.
The
otoliths are used in various studies such as age determination, fish growth and population dynamics all over the world (Bostanci et al.); however, the
otolith morphology and shape indices for D.
After ultrasonic cleaning, the
otoliths were baked in an oven for 24 hour at 50C until a constant mass and weight to the nearest 0.01 mg were achieved.
A chemical element called strontium accumulates on the
otoliths (ear bones) during the lifetime of the fish, similar to the way rings form in a tree.
