Water Quality Prediction for Smart Aquaculture Using Hybrid Deep Learning Models

IEEE Access, Journal Year: 2022, Volume and Issue: 10, P. 60078 - 60098

Published: Jan. 1, 2022

Water quality prediction (WQP) plays an essential role in water management for aquaculture to make production profitable and sustainable.In this work, we propose hybrid deep learning (DL) models, convolutional neural network (CNN) with the long short-term memory (LSTM) gated recurrent unit (GRU) WQP.CNN can effectively fetch characteristics, whereas GRU LSTM learn long-term dependencies time series data.We conduct experiments using two different datasets present extensive study on impact of hyperparameters performance proposed DL models.Furthermore, CNN-LSTM CNN-GRU models are compared baseline LSTM, CNN also attention-based models.The results show that outperformed all other terms accuracy computation time.

Food adulteration refers to the alteration of food quality that takes place deliberately. It includes addition ingredients modify different properties products for economic advantage. Color, appearance, taste, weight, volume, and shelf life are such properties. Substitution or its nutritional content is also accomplished spark apparent quality. with species, protein content, fat plant major forms substitution.

Promising Sources of Plant-Derived Polyunsaturated Fatty Acids: A Narrative Review

International Journal of Environmental Research and Public Health, Journal Year: 2023, Volume and Issue: 20(3), P. 1683 - 1683

Published: Jan. 17, 2023

(1) Background: Polyunsaturated fatty acids (PUFAs) are known for their ability to protect against numerous metabolic disorders. The consumption of oily fish is the main source PUFAs in human nutrition and commonly used supplement production. However, seafood an overexploited that cannot be guaranteed cover global demands. Furthermore, it not consumed by everyone ecological, economic, ethical, geographical taste reasons. growing demand natural dietary sources suggests current nutritional insufficient meet needs, less will be. Therefore, crucial find sustainable acceptable all, meeting world population’s needs. (2) Scope: This review aims evaluate recent evidence about alternative plant essential acids, focusing on long-chain omega-3 (n-3) PUFAs. (3) Method: A structured search was performed PubMed engine select available data from interventional studies using non-animal origin. (4) Results: Several promising have emerged literature, such as algae, microorganisms, plants rich stearidonic acid GM plants. costs, acceptance adequate formulation deserve further investigation.

Seafood supply mapping reveals production and consumption mismatches and large dietary nutrient losses through exports in the United Kingdom

Nature Food, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 2, 2025

Abstract Seafood can contribute towards healthy and sustainable food systems by improving public health helping achieve net zero carbon emissions. Here, we provide a high-resolution perspective on UK seafood supplies nutrient flows at the species level. We mapped production (capture aquaculture), trade (imports exports), purchases (within out of home) consumption between 2009 2020. dietary recommendations for finfish were not achieved domestic nor national supplies. Mapping revealed that undergoes substantial losses omega-3 fatty acids, vitamin B 12 D, which could 73%, 46% 7% UK-recommended intakes, respectively, through exports oily fish such as salmon, herring mackerel. Policies should consider promoting greater locally produced to improve system resilience.

Consumers’ Willingness to Pay for Sustainable Seafood Made in Europe

Sustainability of increasing relevance also for seafood markets. The aim this contribution is to analyze consumer preferences and their willingness pay (WTP) different sustainability claims, identify segments according WTP. contingent valuation method was applied elicit consumers' WTP in eight European countries. varies between seven almost 20%, depending on attribute country. Three groups become apparent: the largest group without any additional WTP, a smaller with moderate plus 17%, very small an more than 40%. Clear differences countries are obvious regarding attributes, particularly segment highest A fraction consumers willing significantly higher prices sustainably produced fish from Europe: given that trustful standards well communicated.

Infectious hematopoietic necrosis virus (IHNV, Rhabdoviridae), is the causative agent of infectious (IHN), a disease notifiable to World Organisation for Animal Health, and various countries trading areas (including European Union). IHNV an economically important pathogen causing clinical mortalities in wide variety salmonid species, including main species produced aquaculture, Atlantic salmon (Salmo salar) rainbow trout (Oncorhynchus mykiss). We reviewed scientific literature on range topics, geographic distribution; host range; conditions required infection disease; minimum dose; subclinical infection; shedding by infected fish; transmission via eggs; diagnostic tests; load survival tissues. This information purposes import risk assessments; parameterisation models; surveillance planning; evaluation chances eradication name just few.

The seafood supply chain from a fraudulent perspective

Food fraud is an intentional act for economic gain. It poses a risk to food integrity, the economy, public health and consumers' ethics. Seafood one commodity which has endured extensive fraudulent activity owing its increasing consumer demand, resource limitations, high value complex supply chains. essential that these opportunities are revealed, evaluated countermeasures mitigation assigned. This can be achieved through mapping of seafood chains identifying vulnerability analysis critical control points (VACCP), exposed, infiltrated exploited activity. research systematically maps chain three key commodities: finfish, shellfish crustaceans in United Kingdom. Each comprised multiple stakeholders across numerous countries producing diverse range products distributed globally. For each prospect fraud, with reference species substitution, fishery illegal, unreported unregulated adulteration, custody abuse, catch method undeclared product extension, modern day slavery animal welfare, been identified evaluated. within provides foundation rank known emerging risks develop proactive plan assigns measures responsibility where vulnerabilities exist.

National authorities in many countries advise their populations to eat more seafood, for health and sometimes environmental purposes, but give little guidance as what type of seafood should be consumed. The large diversity species production methods results variability both the nutritional content performance seafoods. More targeted dietary advice sustainable consumption requires a better understanding relative benefits against costs various types seafood. This study analyzes combined climate commonly consumed Sweden, originating all over world. Nutrient density scores, assessed by seven alternative methods, are with species- technology- origin-specific greenhouse gas emission data 37 An integrated score indicates which products provide greatest value at lowest hence promoted from this perspective. Results show that seafoods Sweden differ widely well impact two measures not correlated across species. Dietary changes towards increased choices where correlation exists (e.g. pelagic like sprat, herring mackerel) would benefit climate. Seafoods higher relation shrimp, Pangasius plaice) should, on other hand, advice. effect individual nutrients implications different nutrient scores is evaluated. research first step modelling joint concrete baseline policy-making, e.g. It followed up species, including toxins nutrition score, expanding cover aspects.
