Components of antenatal care received by women in fishing communities on Lake Victoria, Uganda; a cross sectional survey

Background Uganda has one of the highest maternal deaths at a ratio of 336 per 100,000 live births. As Uganda strives to achieve sustainable development goals, appropriate antenatal care is key to reduction of maternal mortality. We explored women’s reported receipt of seven of the Uganda guidelines ...

Shifting food web structure during dam removal—Disturbance and recovery during a major restoration action

We measured food availability and diet composition of juvenile salmonids over multiple years and seasons before and during the world’s largest dam removal on the Elwha River, Washington State. We conducted these measurements over three sediment-impacted sections (the estuary and two sections of the ...

Turbulence Modelling Capabilities of ILES for Propeller Induced URN Prediction

Over the last decades underwater radiated noise due to human shipping activities increased significantly, which has proven adverse effects on the perception of fish and marine mammals. To protect and preserve marine biology, regulations regarding acoustic emissions of ships and specifically underwater ...

Riding the Chine: A Case Study in Commercial Fishing Vessel Stability

While transiting off the Southeastern Connecticut coast in 2019, F/V Emma & Maria experienced a knock down incident. This paper investigates the causal factors of this event, specifically focusing on stability challenges common to the New England commercial fishing fleet. After identifying contributing ...

Hull Form Performance of a Coastal Patrol Boat in the Gulf of Guinea

A revival of piracy activities and an increase in illegal, unreported, and unregulated fishing in the Gulf of Guinea forced governments to take actions against those illicit maritime activities. A new vessel type was selected to help in fighting these threats. The rapid patrol boat RPB33 is designed ...

Amino Acid Profile and Protein Quality Assessment of Macroalgae Produced in an Integrated Multi-Trophic Aquaculture System

Seaweeds are a recognized source of bioactive compounds and techno-functional ingredients. However, its protein fraction is still underexplored. The aim of this study was to determine the total and free amino acid profile and protein content of four seaweeds species (Porphyra dioica, Porphyra umbilicalis,Gracilaria ...

Fine-scale population structure and evidence for local adaptation in Australian giant black tiger shrimp (Penaeus monodon) using SNP analysis

Background Restrictions to gene flow, genetic drift, and divergent selection associated with different environments are significant drivers of genetic differentiation. The black tiger shrimp (Penaeus monodon), is widely distributed throughout the Indian and Pacific Oceans including along the western, ...

Development of a SNP linkage map and genome-wide association study for resistance to Aeromonas hydrophila in pacu (Piaractus mesopotamicus)

Background Pacu (Piaractus mesopotamicus) is one of the most important Neotropical aquaculture species from South America. Disease outbreaks caused by Aeromonas hydrophila infection have been considered significant contributors to the declining levels of pacu production. The current implementation ...

Microbial Conversion of Shrimp Heads to Proteases and Chitin as an Effective Dye Adsorbent

As a green and effective technique in the production of a large number of valuable products, the microbial conversion of chitinous fishery wastes is receiving much attention. In this study, protease production using the Paenibacillus mucilaginosus TKU032 strain was conducted on culture media containing ...

Nilonema gymnarchi (Nematoda: Philometridae) and trace metals in Gymnarchus niloticus of Epe lagoon in Lagos State, Nigeria

The presence of trace metals in the sediment, water, and biota of the Epe lagoon has been recently linked to oil exploration and municipal perturbations around the lagoon. The study was aimed at assessing the concentrations and associated health risks of Fe, Zn, Cu, Ni, Pb, Cd, Cr, Mn, Co and V in the ...

Impact of unequal distances among acoustic sensors on cross-correlation based fisheries stock assessment technique

Cross-correlation based fisheries stock assessment technique utilized array of multiple acoustic sensors which were equidistant pair. However, at practical implementation of this technique, equal distances among acoustic sensors is sometimes challenging due to different practical phenomenon. Therefore, ...

A spatiotemporal comparison of length-at-age in the coral reef fish Acanthurus nigrofuscus between marine reserves and fished reefs

Quantitative assessments of the capacity of marine reserves to restore historical fish body-size distributions require extensive repeated sampling to map the phenotypic responses of target populations to protection. However, the “no take” status of marine reserves oftentimes precludes repeated sampling ...

Modelling parameter uncertainty reveals bushmeat yields versus survival trade-offs in heavily-hunted duiker Cephalophus spp.

Reliably predicting sustainable exploitation levels for many tropical species subject to hunting remains a difficult task, largely because of the inherent uncertainty associated with estimating parameters related to both population dynamics and hunting pressure. Here, we investigate a modelling approach ...

Investigating impacts of and susceptibility to rail noise playback across freshwater fishes reveals counterintuitive response profiles

Abstract While the expansion of anthropogenic noise studies in aquatic habitats has produced conservation-based results for a range of taxa, relatively little attention has been paid to the potential impacts on stream fishes. Recent work has shown responses to road noise in single species of stream ...

Application of Image Detection of Algae on Aquaculture

Due to the pollution of oceans and overfishing, the catching numbers of wild fish have been greatly reduced. So the aquaculture fishery has gradually become one of the important industries in Taiwan. However, aquaculture still needs to conform to natural ecosystem food chain, and the lowest producer ...

Multiplexed Immunosensor Based on the Amperometric Transduction for Monitoring of Marine Pollutants in Sea Water

Environmental pollutants vigilance is one of the main problems that the aquaculture industry has to face with the objective to ensure the quality of their products and prevent entrance in the food chain that finally may arrive to the consumer. Contaminants such as hormones, antibiotics or biocides are ...

Monitoring Harsh Coastal Environments Using Polarimetric Sar Data: The Case of Solway Firth Wetlands

In this study, the capability of polarimetric Synthetic Aperture Radar (SAR) measurements to monitor harsh coastal areas is addressed. A meaningful showcase is presented that refers to the Scottish Solway Firth (SF) wetlands, an important coastal ecosystem severely affected by extreme weather conditions. ...

Accelerating Sustainable Development with Earth Intelligence

The global community is increasingly recognizing the value of scalable and accurate Earth Intelligence in the pursuit of the United Nations Sustainable Development Goals (SDGs). This paper reviews several case studies where public and private sector organizations are leveraging Earth Intelligence, a ...

Towards Automatic Detection of Dark Features in the Barents Sea using Synthetic Aperture Radar

Increased human presence and commercial activities in the Barents Sea (fishing, offshore oil and gas exploration) are amplifying the need for large-scale operational ocean monitoring of the eventual oil spills in the region. The geographical location and climate impose additional constraints on satellite-based ...
