Reproductive biology of the loliginid squid, Alloteuthis subulata, in the north-east Atlantic and adjacent waters
A study of the reproductive biology of the loliginid squid, Alloteuthis subulata in the North Sea, Irish Sea and Portuguese waters was carried out. A predominance of small squid (<50 mm ML) during autumn was observed in all three areas. Multi-modal size-frequency distributions were apparent in both sexes. The greatest complexity was observed in Portuguese waters, with males exhibiting possibly ...
متن کاملLength-Weight relationship, Condition factor and length frequency of rock oyster, Saccostrea cucullata in coastal waters of Persian Gulf
This study aimed to achieve length frequency, condition factor and length-weight relationship of the rock oyster, Saccostrea cucullata in the coastal waters of Persian Gulf. Sampling was carried out by 0.25 m2 quadrat through intertidal zone from winter 2015 to autumn 2016. According to the results, length-weight relationship calculated as W=0.000004L2.79 for both sexes. In addition, coefficien...

The aim of this study was to record the length-weight relationship and condition factor of A. maculatus from Persian Gulf coastal waters. The specimens were collected on a monthly basis from April to March 2013. Overal 766 specimens were caught. Size and weight of collected fish ranged between 13/2-48 cm and 31.2-1820 gr. The Condition of the growth fish was allometrically negative with b val...
متن کاملLength-weight relationships, condition factor and morphometric characteristics of ten Spirlin (Alburnoides Jeitteles, 1861) species from Iranian inland waters
The length-weight relationships, condition factor and morphometrics of 10 species of the genus Alburnoides are provided from Iranian inland water. The a values ranged from 0.0037 (Alburnoides damghani) to 0.0128 (Alburnoides namaki), the b values ranged from 2.87 (A. namaki) to 3.50 (A. damghani) and the coefficient of variation (r2) ranged from 0.90 (Alburnoides samii) to 0.99 (A. namaki). Of ...
متن کاملReflective properties of iridophores and fluorescent 'eyespots' in the loliginid squid Alloteuthis subulata and Loligo vulgaris.
Observations were made of the reflective properties of the iridophore stripes of the squid Alloteuthis subulata and Loligo vulgaris, and the likely functions of these stripes are considered in terms of concealment and signalling. In both species, the mantle muscle is almost transparent. Stripes of iridophores run along the length of each side of the mantle, some of which, when viewed at normal ...
