In this paper the authors have analyzed the heavy metals influence on the ichthyo fauna state and systematized it, classified the aquatic ecosystem states, developed the mathematical model for their identification based on a modified Perceptron, to create a functional and information-logical model of ...
The combination of two devices of cost effective, sidescan sonar and towed camera was used for mapping of benthic habitat. The application of this system in shallow water allowed the recognition of habitat more detailed and validated the acoustic images through the videos, establishing a ground truth. ...
Among the several ways that human activities interfere in oceanic environment, acoustic noise is recognized as one of the most pervasive. Man-produced noise can have important consequences in marine fauna, since it impacts animal hearing as well as physiological and behavioral responses of oceanic organisms, ...
The study area encompasses the Puyuhuapi fjord (300 m depth) and Jacaf channel (200-400 m depth), located at ~44° S in Patagonia. The Puyuhuapi fjord is connected to the open ocean by two mouths, where at one mouth, a shallow sill inhibits ventilation of deep fjord water. This study is aimed to improve ...
The platform STELLA MARE (Sustainable TEchnologies for LittoraL Aquaculture and MArine REsearch) has for objective to bring responses in the management of the sea in relation with the professional fishing. In this paper, we introduce an experiment on the monitoring of Homarus Gammarus. Using a passive ...
Currently, one alternative for dietary fish oil (FO) in aquafeeds is vegetable oils (VO) that are devoid of omega-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFAs). Entirely new sources of n-3 LC-PUFA such as eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids through de novo production are ...
Cytochrome P450 monooxygenases (P450s) are heme-thiolate proteins whose role as drug targets against pathogens, as well as in valuable chemical production and bioremediation, has been explored. In this study we performed comprehensive comparative analysis of P450s in 13 newly explored oomycete pathogens. ...
Although there are considerable site-based data for individual or groups of ecosystems, these datasets are widely scattered, have different data formats and conventions, and often have limited accessibility. At the broader scale, national datasets exist for a large number of geospatial features of land, ...
The invasion of anthropogenic carbon dioxide (CO2) into the ocean is shifting the marine carbonate system such that saturation states of calcium carbonate (CaCO3) minerals are decreasing, and this is having a detrimental impact on early life stages of select shellfish species. The global, secular decrease ...
Tick-borne diseases are a growing public health concern as their incidence and range have increased in recent decades. Lyme disease is an emerging infectious disease in Canada due to northward expansion of the geographic range of Ixodes scapularis, the principal tick vector for the Lyme disease agent ...
Objective Perivitelline fluid (PVF) of the horseshoe crab embryo has been reported to possess an important role during embryogenesis by promoting cell proliferation. This study aims to evaluate the effect of PVF on the proliferation, chromosome aberration (CA) and mutagenicity of the dental pulp stem ...
There is increasing evidence of the contribution of irrigation water in the contamination of produce leading to subsequent outbreaks of foodborne illness. This is a particular risk in the production of leafy vegetables that will be eaten raw without cooking. Retailers selling leafy vegetables are increasingly ...
The binding interaction between gallic acid (GA) and lysozyme (LYS) was investigated and compared by molecular dynamics (MD) simulation and spectral techniques. The results from spectroscopy indicate that GA binds to LYS to generate a static complex. The binding constants and thermodynamic parameters ...
The Karoun River is major source of water for warmwater fish culture industry in southwest of Iran. The aim of the present study was to investigate the distribution of mercury in tissues of marketable common carp and in bottom sediments of fish farms in Khouzestan province. This study was carried out ...
This study was conducted to determine the effects of mannan oligosaccharide (MOS) on growth, some immune responses and gut lactic acid bacteria of common carp. Four experimental diets containing 0%, 0.05%, 0.10% and 0.20% MOS were prepared. Each diet was randomly allocated to triplicate groups of fish ...
We developed a 2D deterministic and probabilistic model to describe Jack Mackerel (Trachurus murphyi) potential habitat using satellite oceanography data and positional variables. The period of analysis was from January 2011 to December 2014, one test by fortnight, i.e., 96 tests in 4 years. Catches ...
Identifying the various drivers of marine ecosystem regime shifts and disentangling their respective influence are critical tasks for understanding biodiversity dynamics and properly managing exploited living resources such as marine fish communities. Unfortunately, the mechanisms and forcing factors ...
The distribution of fish in the water column, particularly of demersal species near the seabed, is relevant to the detection and assessment of fish populations. Here, acoustic data recorded during six consecutive seasons on the Patagonian stock of argentine hake (Merluccius hubbsi) provided detailed ...
We have been using scientific echo-sounders to map and quantify Engraulis anchoita in the Southern coast of Brazil. This is a low trophic level species and a link from primary producers to top predators. Echo-records collected along thousands of nautical miles contain information about migratory habits ...
In a fishery assessment context, Artificial Neural Networks (ANNs), among other techniques, have been intensively tested for the identification of fish species and pursuing the automatic classification of the schools, based on descriptors extracted from digital echosounder recordings. Prediction of ...
