There have been recent changes in the Caspian Sea ecosystem, such as those due to changes in sea level or those caused by the invasive ctenophore, Mnemiopsis leidyi. It is believed that these changes had significant impacts on the absolute and relative abundance of the commercially important anchovy kilka (Clupeonella engrauliformis) and common kilka (C. cultriventris caspia) leading to decline...

Anchovy fillets that had undergone osmotic dehydration and response surface methodology (RSM) were used to determine the influence and optimal values of the process variables. Also the optimal processing conditions were determined in order to reduce the solid gain and water loss ratio (SG/WL) and firmnessfor the anchovy fillets. A three-levelcentral composite rotatabledesign (CCRD) involving th...
sagax and round herring Etrumeus whiteheadi are the major components of the pelagic fishery in the southern Benguela upwelling system, which encompasses the west coast of South Africa and the western Agulhas Bank at the southernmost extremity. Commercial catches since the 1970s have, until recently, been dominated by anchovy. The species is relatively short-lived (≈ 3 years) and the fishery is ...
BACKGROUND Aerosolization of seafood and subsequent inhalation, during processing is a potential high-risk activity for allergic respiratory disease. OBJECTIVES To quantify total thoracic particulate, protein concentration and specific fish (pilchard, anchovy) antigen concentrations in fish processing plants; to determine the correlation between these exposure metrics; and to identify the maj...
The aim of the present study was to investigate the age structure, length-weight relationship, sex ratio, sexual maturity stages, growth parameters, natural and fishing mortality coefficients of three species of kilka including common, anchovy and bigeye kilka. The fork length–weight relationship of common, anchovy and bigeye kilka were calculated as W=0.000153 FL2.37, W=0.000349 FL2.18 and W...
In this study, the identification of dominant fish species in East Sea was conducted using dB-difference method. The survey two frequencies 38 and 120 kHz transect 6 southern part Sea.

In the Pacific Ocean, air and ocean temperatures, atmospheric carbon dioxide, landings of anchovies and sardines, and the productivity of coastal and open ocean ecosystems have varied over periods of about 50 years. In the mid-1970s, the Pacific changed from a cool "anchovy regime" to a warm "sardine regime." A shift back to an anchovy regime occurred in the middle to late 1990s. These large-sc...
This paper aimed to investigate the fishery and biological characteristics of anchovy Kilka in Iranian waters of the Caspian Sea from 2005-2007, including length and age structure ,Von Bertalanffy growth parameters, length and age at first capture, condition factor, sex ratio, natural and fishing mortality. The examination of catch data approved that Kilka population in the Caspian S...
Large quantities of DDT and polychlorinated biphenyls (PCBs) have been historically discharged to the Southern California Bight (SCB). While these contaminants have bioaccumulated in sediment-associated fishes, little data exist on concentrations of these compounds in pelagic forage species that are the likely food source for larger predatory mammals and birds. The goal of the present study was...
