Assessing population structure of European Anchovy (Engraulis encrasicolus) in the Central Mediterranean by means of traditional morphometry

open access: yesAdvances in Oceanography and Limnology, 2011
For the first time the structure of the anchovy stock was investigated in the Strait of Sicily: sampling locations were in Sicily, in Tunisia and in the Adriatic Sea.

Otolith shape discrimination of Liza ramada (Actinopterygii: Mugiliformes: Mugilidae) from marine and estuarine populations in Tunisia [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2017
Background. The thinlip grey mullet, Liza ramada (Risso, 1810), is widespread in Tunisia. Despite its economic importance, the stock discrimination of this fish is poorly understood.

Otolith shape classification for fish stock discrimination

open access: yesInternational Image Processing, Applications and Systems Conference, 2014
The shape analysis of otoliths, which are calcified structures in the inner ear of teleostean fishes, is known to be particularly relevant to address species identification and stock discrimination. Generally, scientists use classical methodologies of statistical analysis and shape recognition such as Fourier shape descriptors and Principal Component ...

Fuzzy cross-entropy, mean, variance, skewness models for portfolio selection

open access: yesJournal of King Saud University: Computer and Information Sciences, 2014
In this paper, fuzzy stock portfolio selection models that maximize mean and skewness as well as minimize portfolio variance and cross-entropy are proposed. Because returns are typically asymmetric, in addition to typical mean and variance considerations,

Next generation sequencing of Y-STRs in father-son pairs and comparison with traditional capillary electrophoresis

open access: yesForensic Sciences Research, 2021
To evaluate the promising advantages of massively parallel sequencing (MPS) in our casework, we analysed a total of 33 Y-chromosomal short tandem repeats (Y-STRs) with traditional capillary electrophoresis (CE) and 25 Y-STRs using the newer MPS ...

Otolith morphometrics distinguish difficult species of rockfishes in the Gulf of Alaska

open access: yesFrontiers in Marine Science, 2015
The oceans around Alaska are home to at least 40 species of rockfishes (Sebastidae). A number of these species are commercially important and are subject to strict catch limitations.
