Assessment of Potential Health Risks Associated with the Intake of Heavy Metals in Fish Harvested from the Largest Estuary in Colombia

This study assesses the potential human health risks posed by six heavy metals (Hg, As, Pb, Cd, Cu, and Zn) found in five of the most consumed fish species (Mugil incilis, Centropomus undecimalis, Cathorops mapale, Eugerres plumieri, and Elops smithi) collected by the riverine population living in Ciénaga ...

‘Get a Fish’ vs. ‘Get a Fishing Skill’: Farmers’ Preferred Compensation Methods to Control Agricultural Nonpoint Source Pollution

Ecological compensation is an important means for controlling agricultural nonpoint source pollution, and compensation methods comprise an essential part of the compensation policy for mitigating this form of pollution. Farmers’ choice of compensation methods affects their response to compensation policies ...

Diversity of the southern Africa Lacustricola Myers, 1924 and redescription of Lacustricola johnstoni (Günther, 1894) and Lacustricola myaposae (Boulenger, 1908) ( Cyprinodontiformes, ...

Abstract Through the analysis of a comprehensive database of COI sequences, with the sequencing of 48 specimens, a first insight into the genetic diversity, distribution and relationships between the southern Africa “Lacustricola” species is presented. Species from “Lacustricola” occur mainly in freshwater ...

Field testing of impressed current anodes and long-term reference electrodes for cathodic protection of harbor and jetty facilities in sea water (Russian)

Transneft operates four marine terminals nowadays. Due to steady upgrade and ramping up of their throughput capacity, the issues of harbor infrastructure integrity maintenance and safe operation become of a vital importance. In particular, to enhance corrosion reliability of marine harbor and jetty ...

Ship Target Detection Based on LightGBM Algorithm

Along with the increasingly prominent role of ship automatic detection in the search and rescue of distressed ships, combating illegal fishing, marine traffic control and marine warfare, this paper proposes a ship detection method based on shape and texture features. Firstly, this article extracts the ...

Machine Learning-Assisted Anomaly Detection in Maritime Navigation using AIS Data

The automatic identification system (AIS) reports vessels' static and dynamic information, which are essential for maritime traffic situation awareness. However, AIS transponders can be switched off to hide suspicious activities, such as illegal fishing, or piracy. Therefore, this paper uses real world ...

Effects of Nutrient Limitation on the Synthesis of N-Rich Phytoplankton Toxins: A Meta-Analysis

Eutrophication has played a major role in the worldwide increase of harmful algal blooms (HABs). Higher input of key nutrients, such as nitrogen (N) and phosphorus (P), can stimulate the growth of harmful algal species in freshwater, estuarine, and coastal marine ecosystems. Some HAB-forming taxa, particularly ...

Enrichment, Source Apportionment and Health Risk Assessment of Soil Potentially Harmful Elements Associated with Different Land Use in Coastal Tidelands Reclamation Area, ...

Coastal tidelands are important ecological habitat resources and valuable resources for agricultural land reclamation. Enrichment of potentially harmful elements (PHEs) in soil caused by anthropogenic activity is an important factor implicated in the ecological deterioration of soil in China. A total ...

Opportunities and challenges of phenomics applied to livestock and aquaculture breeding in South America

On The Application of SiO2/SiC Grating on Ag for High-Performance Fiber Optic Plasmonic Sensing of Cortisol Concentration

This paper reports on high-accuracy simulation of a grating structure based fiber optic plasmonic sensor for salivary cortisol sensing. Gratings of SiO2 and SiC (one at a time) in combination with a thin Ag layer are considered to be in direct contact with analyte medium (solutions containing different ...

Dietary diversity and fish consumption of mothers and their children in fisher households in Komodo District, eastern Indonesia

Small-scale coastal fisheries contribute directly and indirectly to the food and nutrition security of marine-dependent households. Fishers can apportion part of their catch for household consumption or use the income earned to purchase staples and other desired foods. Fish are an important animal-source ...

MapReduce-Based BP Neural Network Classification of Aquaculture Water Quality

As information technology develops and prevails across the globe, the informatization and data processing efficiency in the aquaculture field are exerting increasing impact on the intelligent conversion of this field. The aquaculture water quality indicators were analyzed by a feedforward error back ...

Implementation of Water Quality Management Platform for Aquaculture Based on Big Data

In order to ensure the quality and quantity of aquaculture, aquaculture farmers need to grasp the water quality in time. However, most farmers have to collect water quality data manually at present, and cannot store and reuse that information rapidly. This paper aims to use SpringBoot framework and ...

Smart and Sustainable Home Aquaponics System with Feature-Rich Internet of Things Mobile Application

Food security has been a recurring issue for many countries in the world including Singapore. This issue is exacerbated by growing world population and climate change, which inevitably leads to an increased demand for food. In recent years, large scale aquaponics has shown efficient production of edible ...

Understanding the Land Use and Water Systems of the Mekong River

The Mekong River region’s long-term social and economic sustainability is being threatened by the growing development of hydropower and its impacts on the river, surrounding populations, and vital industries. In this study we have analyzed these unintended impacts through data analysis in hopes of quantifying ...

Feasibility of Internet of Things and Agnostic Blockchain Technology Solutions: A Case in the Fisheries Supply Chain

Along with Internet of Things -IoT-, distributed ledger/blockchain technology can provide substantial benefits to the management of supply chains. However the adoption of blockchain-based solutions may face substantial challenges such as scalability, which happens when several parties have to access ...

Viability Analysis of a Stock-Capital Fishery Model

This work is based on C. Clark, F.Clarke and G. Munro (C.C.M) fishery model, [1], where the dynamic is the evolution of both stock and capital controlled by the investment and the part of the capital dedicated to the harvest. The contribution of the present work consists of substituting the profit maximization ...

An in-feeding and object release apparatus

The present invention relates to a method and a device for individual feeding of fish into a processing line. Such method and device may, for instance, be used for receiving, gilling and gutting freshly caught fish in a processing line on board a fishing vessel. For instance, the in-feeding apparatus ...

Anti-Fouling Effects of Saponin-Containing Crude Extracts from Tropical Indo-Pacific Sea Cucumbers

Sea cucumbers are bottom dwelling invertebrates, which are mostly found on subtropical and tropical sea grass beds, sandy reef flats, or reef slopes. Although constantly exposed to fouling communities in these habitats, many species are surprisingly free of invertebrate epibionts and microfouling algae ...

Visual Storytelling, Intergenerational Environmental Justice and Indigenous Sovereignty: Exploring Images and Stories amid a Contested Oil Pipeline Project

Visual practices of representing fossil fuel projects are entangled in diverse values and relations that often go underexplored. In Canada, visual media campaigns to aggressively push forward the fossil fuel industry not only relegate to obscurity indigenous values but mask evidence on health impacts ...
