To conserve and manage fish stocks in fisheries, people monitor the growth and quantities of fish by collected underwater videos and images. However, the efficiency of finding fish from videos and images is limited by manual operation. In this paper, we propose an automatic method to improve the efficiency ...
Seawater chlorophyll-a (Chla) represents algal biomass in ocean and is a major index of eutrophication. In this paper, bootstrapped artificial neural network (BANN) model is developed for predicting the seawater Chla concentration around the north Pacific Rim. Three-layer ANN structure is applied and ...
Thermocline has a significant impact on marine fishery, navy submarine activity, ocean circulation and internal wave. In consideration of long range, low cost, and high maneuverability, the AUV (Autonomous Underwater Vehicle) is an ideal platform for ocean local precisely thermocline tracking. Combining ...
Acoustic systems are used widely to provide quantitative estimates of biomass for fisheries and ecosystem assessments. Traditionally, these systems are attached to surface vessels, but increasingly they are being fitted to remote operated vehicles, autonomous vehicles and towed platforms. These platforms ...
In this study the cranial nerves development of H. huso are explained from 1 to 54-days-old (1, 3, 6, 15, 21 and 54 days). Despite all the researches on fish brain, there are no study on nerves evolution on H. huso during their larvae life. For this research 40 samples of larvae H. huso were obtained ...
The present study was conducted to evaluate the effect of fish oil supplementation prior to mating on secondary sex ratio of pups (the proportion of males at birth) in bitches. Sixty five bitches (German Shepherd, n = 35; Husky, n = 30) were enrolled in the study. Bitches (140-150 days post-estrus) ...
Here we provide data on accessibility of nucleolus-like bodies (NLBs) of fully-grown (GV) mouse oocytes to fluorescence in situ hybridization (FISH) probes and anti-nucleolar antibodies as well as on oocyte general morphology and large scale chromatin configuration, which relate to the research article ...
Nascent transcripts being copied from specific human genes can be detected using RNA FISH (fluorescence in situ hybridization) with intronic probes, and the distance between two different nascent transcripts is often measured when studying structure–function relationships. Such distance measurements ...
Objective Advanced maternal age (AMA) is an important factor in decreasing success of assisted reproductive technology by having a negative effect on the success rate of intra-cytoplasmic sperm injection (ICSI), particularly by increasing the rate of embryo aneuploidy. It has been suggested that the ...
The aim of this paper is to analyze the current international regulation of exploration and exploitation of gas and oil in the ocean in order to provide legal recommendations to preserve marine biodiversity and to prevent climate change in oceans. Offshore oil and gas exploration has been increasing ...
This article analyzes mismatches between syntactic and prosodic constituency in Irish and attempts to understand those mismatches in terms of recent proposals about the nature of the syntax-prosody interface. It argues in particular that such mismatches are best understood in terms of Selkirk’s (2011) ...
Background Following extreme climatic warming events, Eocene Lagerstätten document aquatic and terrestrial vertebrate faunas surprisingly similar to modern counterparts. This transition in marine systems is best documented in the earliest teleost-dominated coral reef assemblage of Pesciara di Bolca, ...
The grass carp (Ctenopharyngodon idella) is a herbivorous, freshwater fish species of the family Cyprinidae, and the only species of the genus Ctenopharyngodon. Neoplasms in fishes are generally less aggressive than neoplasms in mammals and are most commonly discrete, focal and benign neoplasms. A 3-year-old ...
In this article, the authors identify the correlative and complementary relations among multiple modalities. They then propose a multimodal ensemble fusion model to capture the complementary relation and correlative relation between two modalities (images and text) and explain why this ensemble fusion ...
The Automatic Identification System is an electronic system enabling vessels to send localization messages. Those messages are used for several uses such as fleet control, traffic control or boarding prevention. Sent messages contain errors, falsifications and undergo spoofing due to the unsecured channel ...
Study the consumer behavior has been always of great interest to researchers, specifically, when the researchers want to study the choice behaviors of customers with instant purchase. The aim of current study is to affect customer choice behaviors by making several changes in e. menu design, exactly ...
In support of ecosystem and fisheries studies, the CSIRO has developed and deployed a variety of towed and tethered acoustic and optical systems to quantify fish biomass and characterize the ecosystem. The most recent of these platforms — the acoustic and optical system (AOS) — was designed to provide ...
Aquatic unmanned robotic systems have gained popularity due to their abilities to perform a wide range of applications at low cost and no risk to human lives. This research investigates the development of the navigation system of “HPftN”, an Autonomous Surface Vehicle (ASV). The PID control system composed ...
This paper used DIDSON to get information of underwater fish and carried out the real-time multiple-target tracking, particularly the targets were dense. Analysis of fishery resources was also done through the data post-processing. Realtime data processing mainly included DIDSON image building/enhancement/filter, ...
As the main nutrient inputs of ECS, nutrient concentrations of the Yangtze River increase significantly due to high-speed economy development, which play a very important impact on the East China Sea ecosystem. In this study, by integrating MEC model and Ecosim model, we analyzed the impacts of Yangtze ...
