In this study, a female specimen of common sole (Solea solea) with 36.7 cm in total length and 466.0 g weight was caught off Ordu region (eastern Black Sea, Turkey) trammel net at 10 m water depth on May 6, 2021. The age determined to be 6 years old. Measured were the maximum value Solea solea Turkish coast Sea.

We solve the problem of designing a simple device that uses rotary motion to drill a hole with a cross-section that is a regular polygon with an odd number of sides: the main idea is to use a polygonal trammel and a family of rotors. By using different rotors, one can produce a hole with a cross-section that is in any proportion of the trammel size from zero to exactly one. The key geometric id...

Crustaceans (Arthropoda) are a diverse and abundant group with chitinous exoskeleton, living on coastal/estuarine environments, at community invertebrate fauna.
