Background. The barred spiny eel, Macrognathus pancalus Hamilton 1822 (known also as the striped spiny eel) has high food- as well as ornamental value in India and its neighbouring countries. The natural resources of this species are declining due to over exploitation and habitat changes. The aim of this study was to provide necessary inputs on food habits, reproductive biology, and fishery of the...
One specimen (TL = 532 mm, W = 662 g) of the yellowmouth barracuda, Sphyraena viridensis, was caught by an angler on 3 August 2008 in front of the Port of Rijeka (Northern Adriatic). Being caught at the geographic latitude of 45°17′N, makes this record the northernmost occurrence of this species in the Mediterranean.
Background. The examination of morphological features related to feeding in fish, as well as their relation with body length, are of increasing scientific interest. In the present study, information on intestine (gut) morphometrics that appear in the relevant literature has been compiled, analysed, and discussed. Materials and Methods. Search of gut-related bibliography was conducted, using online...
Background. Hatching is a process in which the embryo emerges from the egg by breaking the protective egg shell. Our preliminary observations indicate that hatching duration and time-distribution may vary among and within the fish species, and that some embryos fail to hatch or hatch incompletely, probably due to the “incorrect” hatching way. So the aim of this study was a detailed description of...
In this study, parameters of the length–weight relation (LWR) were estimated for fifteen species of Gerreidae (mojarras) caught from the Pacific- and Atlantic coast of Mexico, including the Gulf of California. The Pacific species were: Diapterus aureolus, Diapterus brevirostris, Eucinostomus currani, Eucinostomus dowii, Eucinostomus entomelas, Eucinostomus gracilis, Eugerres axillaris, Eugerres lineatus,...
Background. Stocks of many marine fishes are in decline and a number of studies suggest that for some species the impact of recreational angling may be important. To date, only recreational (leisure) fishing surveys have been conducted in Portugal, with no studies on beach angling competitions, dynamically increasing in number over the past 10 to 20 years. In view of the above, we decided to evaluate...
