This study was conducted to examine morphometric and meristic characteristics alongside pigmentation patterns of bream larvae, Abramis brama orientalis, in four stages of larval development. Morphological characters including total length (TL), standard length (SL), notochord length (NL), head length (HL), head depth (HD), eye diameter (ED) and mouth width (MW) were examined from hatching time ...

Pleuronectiforme fishes of the Persian Gulf coastlines along Khuzestan, Bushehr and Hormozgan provinces were morphometrically and meristically studied from April 2003 to September 2005, in order to identify species. In this experiment, 1551 fish samples were caught by trawl or collected from fish markets. The sampling was carried out in 27 regions seasonally. Thirty six traits and parameters in...

A detailed systematic account of Sepia (Hemisepius) typica, an endemic southern African species cuttlefish, is presented. An analysis morphological data (morphometric and meristic characters) suggests that S. typica a single well-established without morphs or subspecies. It is, however, highly variable, perhaps more so than other small sepiids from the region, there are slight, but significant ...

Morphometric variation in the squid Loligo forbesi was investigated to quantify effects of region, season, sex and maturity. Practical exercises were carried out using this species and the congeneric Loligo vulgaris to evaluate differences in measurements by different workers. The utility of meristic characters was also examined. Consistent significant differences were found between measurement...

Yellowfin tuna, Thunnus albacares (Bonnaterre, 1788) and bigeye tuna, Thunnus obesus (Lowe, 1839) are two of the most economically important tuna species in the world. However, identification of their juveniles, especially at sizes less than 40 cm, is very difficult, often leading to misidentification and miscalculation of their catch estimates. Here, we applied the mitochondrial DNA control re...

From 2009 to 2011 eleven specimens belonging to four bathygadid species of the family Bathygadidae were captured in two different locations in the northern waters of Spain. The morphometric measurements and meristic characters of these specimens are given. The specimens were identified as belonging to the genera Gadomus Regan, 1903, and Bathygadus Günther, 1878, including the following species:...
