Fisheries co-management is a resource management regime that closely cooperates with local fishers' activities and administrative agencies' legal management measures. In Japan, historically the fisheries policy has been implemented through co-management. In order to promote and to improve fisheries ...
This paper proposes the use of Deep learning for Marine Resources classification (DeepMaRe), especially the classification of fish images captured in non-structured scenarios. Tests conducted using two state of the art deep CNN architectures show that Deep learning can be used efficiently in this type ...
This study aimed to develop a detailed behavior observation method for deep water fish using pingers and a quantitative echo sounder. We focused on alfonsino (Beryx splendens) inhabiting deep water. The survey was conducted at two locations: one where fishermen operate (experimental area) and another ...
Nowadays, as a sub topic of computer vision and fishery industry, fish recognition is still a challenging work not only because of biodiversity, but also because of the complex background of images. In this paper, we aim to classify different fish images obtained from cameras of fishing vessels. Fish ...
In this paper, we introduce a convolutional neural network based on the state-of-the-art detector, named YOLOv2, to classify and detect images of fish. Meanwhile, we have adopted the relevant customization techniques to optimize the architecture of model. The Nature Conservancy Fisheries Monitoring ...
Conventional tagging methods using plastic streamer tags have been the most widely used tool for elucidating fish movements in the last half century. These methods for fish tagging and tracking are error-prone for tracking global fish populations due to the requirement of fishermen to log details of ...
Red snow crabs are an important resource for the fishing industry. They live at the bottom of the sea, and fish traps are used by fishermen to catch the snow crabs. The fishing period is typically one week, and ideally, the traps should have bait available for the entire duration in order to catch the ...
Determination of appropriate fishing spots is one of the most important activities in the fishing industry. Inspired by the approach followed by fishermen to determine fishing spots, this paper presents a new machine-learning method for uncovering oceanographic patterns related to good fishing spots. ...
An increased awareness of the mounting pressure on the marine ecosystem as well as the enormity of the recreational SCUBA dive industry has brought about a greater awareness of the challenges facing the marine environment. One key issue is destructive fishing. Destructive fishing is a blanket term used ...
Abstract Evolutionary responses to indirect selection pressures imposed by intensive harvesting are increasingly common. While artificial selection has shown that biochemical components can show rapid and dramatic evolution, it remains unclear as to whether intensive harvesting can inadvertently induce ...
Surfactants are compounds that can reduce the surface tension between two different phases or the interfacial tension of the liquid between water and oil, possessing both hydrophilic and hydrophobic moieties. Biosurfactants have traits that have proven to be advantageous over synthetic surfactants, ...
ABSTRACT Rainbow trout (Oncorhynchus mykiss) was recognized as a typical ‘glucose-intolerant’ fish and poor dietary carbohydrate user. Our first objective was to test the effect of dietary carbohydrates themselves (without modification of dietary protein intake) on hepatic glucose gene expression (taking ...
Background: Due to the widespread different pathogenic strains, Escherichia coli lead many severe to normal diseases worldwide. Finding the relation of clones with genomic content and clinical features is a key point to recognize the high potential-invasive strains. Specific virulence factors include ...
Aim: This study aimed to investigate the protective effect of Rosmarinus officinalis (L.) essential oil on rooster sperm motility during 4°C short-term storage. Materials and Methods: R. officinalis essential oil was analyzed using gas chromatography coupled to mass spectrometry to identify the active ...
A parasite exhibiting Oomycete-like morphology and pathogenesis was isolated from discoloured eggs of the European lobster (Homarus gammarus) and later found in gill tissues of adults. Group-specific Oomycete primers were designed to amplify the 18S ribosomal small subunit (SSU), which initially identified ...
Proteins from different fish species and different raw materials such as fish fillets and by-products have shown promising cardioprotective effects in rodents and humans, including effects on cholesterol metabolism. Blue whiting is used mainly to produce fish meal for the feed industry and during this ...
Sewage irrigation has a strong influence on the physical, chemical, and biological properties of soil. However, the effects of sewage irrigation on the pore characteristics of soil are not well understood. This study compares the effects of sewage irrigation and groundwater irrigation on computed tomography ...
Pollutants from pig farms in Mexico have caused problems in many surface water reservoirs. Growing concern has driven the search for low-cost wastewater treatment solutions. The objective of this research was to evaluate the potential of an in-series constructed wetland to remove nutrients from wastewater ...
Quorum sensing (QS) is a mechanism dependent on bacterial density. This coordinated process is mediated by the synthesis and the secretion of signal molecules, called autoinducers (AIs). N-acyl-homoserine lactones (AHLs) are the most common AIs that are used by Gram-negative bacteria and are involved ...
This study aims to evaluate the acute toxicity of pymetrozine to juvenile Procambarus clarkii. Two 96-h toxicity tests were conducted to assess the lethal concentration 50 (LC50) values, behaviors, and histopathology (at 50% of the 96 h LC50) after pymetrozine exposure. The results showed high toxicity ...
