In this study, seven oligonucleotides primers were shown to generate the shared loci, specific loci, unique shared loci to each species and shared loci by the three species which could be obviously calculated. Euclidean genetic distances within- and between-species were also calculated by complete linkage method with the sustenance of the hierarchical dendevrepogram program Systat version 13. T...

A simple model formalizes present ideas concerning the biological and physical oceanographic processes which may influence growth and survival of larvae of the northern anchovy Engraulis mordax. The model simulates the distribution of prey in a turbulent water column. Scale analysis is used to deduce the thickness of the food layer which can be maintained in the face of turbulent dissipation an...

In the 1980s, personnel from the Instituto del Mar del Peru collaborated with foreign experts to reconstruct time series of (1) catch and biomass of the Peruvian anchovy Engraulis ringens back to 1953, along with parallel time series of (2) abundance of anchovy predators and competitors, and (3) abiotic parameters indicative of the dynamics of the Peruvian upwelling system. This contribution do...

The halophilic proteinase showed a maximal activity at 50°C and pH 9~10, in 20% NaCl and was highly stabilized by NaCl. It was able to hydrolyse natural actomyosin (NAM), collagen and anchovy protein. For NAM hydrolysis, the myosin heavy chain was completely digested by halophilic proteinase as evidenced by the lowest band intensity remaining, but partially hydrolysed actin. The SR5-3 proteinas...

The perceived value of oyster reefs as fish habitat has led to many restoration projects in areas of historically high oyster populations. This study evaluated fish usage of a limestone cobble mimic oyster reef in Barataria Bay, Louisiana, as compared to a mud-bottom reference site. Emphasis was given to species of economic and ecological importance, including spotted seatrout (Cynoscion nebulo...

Atlantic-Mediterranean anchovies were genetically characterized at two polymorphic nuclear loci (intron 6 of two creatine-kinase genes) and compared to reference Engraulis albidus and E. encrasicolus samples from the northern Western Mediterranean to provide new insights into their geographic structure. Northeastern Atlantic anchovy, represented by one sample from the Canary archipelago and one...

 The present study was carried out during 2006-2007 along the southern Caspian Sea. The species composition showed that the common kilka, Clupeonella cultriventris caspia, is dominant species with 89% and then anchovy, C. engrauliformis, has shown only 8.7% while it was already dominant species in the past decades. The overall results indicated that common kilka was replaced with anchovy kilka ...

Recruitment of bay anchovy (Anchoa mitchilli) varies annually in Chesapeake Bay, and levels and patterns are related to variability in hydrological conditions and the spatial distribution of spawning stock biomass. Midwater-trawl surveys, conducted three times annually from 1995-1999, over the entire 320-km length of the Bay, provided information on annual and regional patterns of recruitment, ...

Anchovies have been traditionally captured and processed for human consumption for millennia. In the case of Spain, ripened and salted anchovies are a delicacy, which, in some cases, can reach high commercial values. Although there have been a number of studies presenting DNA methodologies for the identification of anchovies, this is one of the first studies investigating the level of mislabell...

The present study considered the situation of kilka stocks in last decades by using overfished biomass threshold, fishing effort ratio and fishing mortality proxy during 1991-2010. The CPUE index of anchovy and mixed-species of kilka indicated an undepleted from 1991 to 2000. In 2000, the CPUE ratio declined to close to the “in danger” region, and subsequently collapsed to “overfished” region f...
