Carapace length

A new freshwater ostracod genus, Comalcandona gen. nov., and its type species (Comalcandona tressleri sp. nov.) are described from John Knox Ranch, Comal County, Texas, USA. The new genus differs from the related genera in the presence of the shallow pits on the trapezoidal shape of the carapace and presence of one well-developed anterior claw (posterior claw and both anterior and posterior setae are absent) on the uropod, a diagnostic character.

The length - weight relationship of Charybdis natator (Herbst, 1794) was studied from Gulf of Mannar for a period of one year. The interrelationship between carapace width, carapace length, chelarpropodus length, weight and abdominal width in males as well as females, were estimated. Fishing activities are carried out throughout the year.

The study, estimated to contribute to generate information to elucidate morphometrics and length-weight relationship and the relative growth of some body parts of the mud crab Scylla serrata. A total of 100 crabs were collected, from January 2018 to January 2019, from Sudanese Red Sea coast of the commercial catch land at Port Sudan. Each specimen was sexed and measured.

The characteristics of age distribution and growth parameters of lobster population (N. norvegicus) in Icelandic waters were analysed based on length frequency distribution and cohort slicing method. The lobster population had twenty five age groups in which the mean carapace length (CL) was ranged from 7.22 mm at the first age to 76.08 mm at the twentieth five ages.
