Aquaculture is considered the fastest-growing food supply, invertebrates being a key element; in particular, whiteleg shrimp (Litopenaeus vannamei). They contribute to human welfare, albeit potential negative environmental effects should be properly addressed. Indeed, the environmental impact of aquaculture is lower than using wild captures. Therefore, shrimp aquaculture is reviewed in relation to

The FAO recently published its biennal State of World Fisheries and Aquaculture up to 2018. The FAO continues to treat the seaweed aquaculture sector as a different category, with separate tables and comments in different sections. As this could lead to a distorted view of total world aquaculture, the statistical information provided by FAO was revisited and data regarding the seaweed aquaculture sector

Polyphenols are plant-derived compounds with known biological activities and potential health benefits. Over the past decade, there are an increasing number of studies have investigated the application of polyphenols and polyphenol-rich additives in aquaculture as functional feed additives. There are several types of polyphenolic compounds such as flavonoids, phenolic acids, lignans, and stilbenes

The prominent functional versatility of pyridoxine makes it an essential dietary nutrient for aquatic animals. Ample investigations have been undertaken to determine the optimum levels of dietary pyridoxine for different commercial fish species. Available literature suggests that the pyridoxine requirement of animals, including fish, varies greatly depending on the dietary protein intake. The present

Over the last 50 years there has been an increased frequency and severity of negative impacts affecting marine fishery and aquaculture sectors, which claimed significant economic losses due to the interference of stinging gelatinous organisms with daily operational activities. Nevertheless, original scientific information on jellyfish-related incidents, their consequences, and potential preventative

Abstract Most tropical small-scale fishing communities, like those of Zanzibar (Tanzania), strongly depend on fisheries resources for income and protein supply. Although imperative, the evaluation of fisheries performance indicators for adequate management is often challenging given the data-poor nature of most of these fisheries. This study reviews the current literature and integrates findings from

This review summarizes and analyses information on freshwater crayfish introductions in Africa. A total of 136 research papers and reports were found to be relevant. Forty-eight percent reported presence; 21% described negative impacts; 11% referred to potential socio-economic benefits; 9% evaluated control measures; 6% documented co-introduced parasites. Out of nine introduced crayfish species, five

In fish, like other organisms, the lack of balance between the production of reactive oxygen species (ROS) and antioxidant defense system (so-called oxidative stress) can cause DNA hydroxylation, protein denaturation, lipid peroxidation, apoptosis, and ultimately cell damage. To improve the antioxidant defense capability, different approaches such as the administration of synthetic antioxidants were

Abstract This study reviews the development and conventional qualitative analysis of aquaculture in Africa, specifically by reviewing the aquaculture sector of key players (Egypt, Nigeria and Uganda) as a reference for South Africa; an aspiring key aquaculture player in Africa based on the launch of Operation Phakisa—South African version of the blue economy initiative. The key players were identified

Policies and legislation for the importation and use of non-native (NN) freshwater fishes have been rapidly evolving in several countries around the world in response to heightened evidence of their adverse ecological and economic impacts. In China, the already large and growing number of NN freshwater fishes being imported from foreign countries or translocated within China has necessitated the development

The Laurentian Great Lakes have experienced recent ecosystem changes that could lead to reductions in adaptive capacity and ultimately a loss of biodiversity and production throughout the food web. Observed changes in Great Lakes benthic communities include declines of native species and widespread success of invasive species like dreissenid mussels in all but Lake Superior. Understanding the ecology

Among immunostimulants used in aquaculture, herbal is promising due to their propensities to improve growth performance, fish immunity, and their antimicrobial properties, as they are good alternatives to chemical treatments and antibiotics. As medicinal herbs are eco-friendly, cost effective, have minimal side effects, and they have gained attention in the prevention and treatment of fish diseases

Abstract Global demand for freshwater and marine foods (i.e., seafood) is rising and an increasing proportion is farmed. Aquaculture encompasses a range of species and cultivation methods, resulting in diverse social, economic, nutritional, and environmental outcomes. As a result, how aquaculture develops will influence human wellbeing and environmental health outcomes. Recognition of this has spurred

Aphanomyces invadans, an oomycyte fungus most frequently recognized as a causative agent of epizootic ulcerative syndrome (EUS) is a seasonal epidemic pathogen of great importance in wild and farmed fish in both freshwater and estuarine environments. EUS is a complex infectious etiology which leads to necrosis ulcerative lesions and granulomatous response in fishes. It is a cause of death of approximately

The common dolphinfish (Coryphaena hippurus) is an epipelagic thermophilic species with a worldwide distribution in tropical and subtropical regions that is characterized by its migratory behavior and fast growth rates. This species is targeted by artisanal small-scale and recreational fisheries in most regions where it is found. This paper updates and analyzes the global scientific knowledge on the

India is blessed with vast floodplain wetland resources of 0.5 million ha that are distributed in the Eastern and North Eastern States. They possess varying morphometry, ecological profile, trophic status and biota, and harbor around 96 fish species, however the fish diversity is declining in recent years due to anthropogenic and other stressors including climate change. The wetlands are serving the

The literature on global trends in recreational fishing, the determinants of participation in recreational fishing, and the social embedding of recreational fishing in the public eye are reviewed across the world. Data support a conceptual life-cycle model of fisheries according to which interest in recreational fishing rises rapidly with economic development before leveling off and eventually declining

Trawl fishing constitutes an important part of the marine fisheries sector in Southeast Asia. It provides livelihoods and food for millions of people in coastal communities as well as feed for the region’s growing aquaculture sector. Trawl fisheries suffer from a multitude of problems, including overcapacity, excessive fishing effort, poor profitability and inadequate governance. The historical decline

Marine recreational fishing (MRF) in Portugal is a traditional leisure activity with considerable importance for coastal populations. In the absence of available information from the national data collection framework, this article aims to review the existing information on MRF across the country. MRF was an open access fishery until recently, but with rising evidence of overexploitation of coastal

Millions of individuals worldwide rely on recreational fishing activities for leisure, food, and employment. Recreational fishing is the dominant freshwater fisheries sector in much of the highly developed world and plays a growing role in the marine realm, but in developing countries recreational fisheries occur within a different set of contextual conditions. Little is currently known about attributes

This species is targeted by artisanal small-scale and recreational fisheries in most regions where it is found. This paper updates and analyzes the global scientific knowledge on the

Otolith chemistry has gained increasing attention as a tool for analyzing various aspects of fish biology, such as stock dynamics, migration patterns, hypoxia and pollution exposure, and connectivity between habitats. While these studies often assume otolith elemental concentrations reflect environmental conditions, physiological processes are increasingly recognized as a modulating and/or controlling

Climate change is the defining environmental problem for our generation. The effects of climate change are increasingly evident and are anticipated to profoundly affect our ability to conserve fish habitats and fish assemblages. Reservoirs are important structures for coping with projected shifts in water supply, but they also provide refuge for riverine fishes and retain distinct fish assemblages

Expedient classification of fishes’ hearing abilities based on detected frequency can inform potential impacts of anthropogenic noise on fish communities. Nevertheless, literature on fish hearing is discordant in methodology and limited to a small fraction of known species. The literature on fish audition (N = 63) supported four classes associated with swim bladder specialization: species without swim

In a global fight against over-nutrition, obesity and associated ailments, identification and consumption of healthier food than processed red meat products and fast-foods is crucial. Fish and seafood products appear as the healthier alternative animal products and the present paper highlight their nutritional merits and health attributes in a world where malnutrition but also under-nutrition is still

Excessive application of antibiotics to control fish and shrimp diseases in aquaculture has been associated with several drawbacks, such as immune suppression, development of antibiotic-resistant bacterial strains, and elevated levels of antibiotic residues in animal products. To overcome this problem and to promote fish health and their productivity, several immunostimulants have been used as additives

Monogenean parasites are responsible for tremendous annual economic losses in both freshwater and marine aquaculture operations. These losses have led to the extensive deployment of chemical treatments, such as praziquantel and mebendazole, in an effort to manage infections from these parasites. While effective, the environmental side effects associated with these treatments are, however, concerning

Egg quality and early embryonic development are important aspects for successful artificial propagation of fish species of ecological and economical values, and therefore have been intensively researched. It has been demonstrated that several maternal factors including TGF-β, cyclin B, follicle cell transcripts and gonadal peptides like inhibins influence fish egg quality. Inhibins are considered gonadal

The research investigates whether cooperative formation through horizontal integration is best way forward to enable small-scale farmers meet certification requirements. The study employed a literature review on the shrimp industry in Vietnam, value chain analysis, cooperative formation through horizontal integration while developing vertical integration linkages with larger lead firms plus a case

Catch-and-release (CR) has become a pervasive practice and “social norm” with anglers for some inland recreational fisheries. This practice has been promoted for fish conservation and to meet angler and manager desires of greater fish abundances, angler catch rates, and trophy growth potential. Catch-and-release in north-temperate inland recreational fisheries was reviewed over time and documented

The Asian arowana (Scleropages formosus) is an ancient freshwater fish species from the Osteoglossidae family. It is a territorial and mouth-brooding fish, which inhabits slow-moving rivers and lakes within forests in Southeast Asia. It produces a small number (20–90 eggs/spawning) but very big eggs (diameter: ∼2 cm). It is highly endangered and has been listed under appendix I of CITES since 1975

The age of sexual maturity of the Atlantic bluefin tuna (Thunnus thynnus; ABFT) is a reference point for stock assessment and management. The International Commission for the Conservation of Atlantic Tunas (ICCAT) recognizes a western and an eastern Atlantic ABFT stock, based on the assumptions of separate, exclusive spawning grounds, i.e., the northern Gulf of Mexico and the Mediterranean Sea, with

Stock structure is one of the fundamental assumptions for assessing and managing fisheries resources. Investigation of stock structure should be conducted holistically, involving reviews of as much information as possible, because suggested conclusions from different studies are often contradictory. Here, all available information related to the stock structure of Pacific bluefin tuna (Thunnus orientalis)

Several investigations have investigated the gut microbiota in shellfish species, but less information is available on the favorable gut bacteria colonizing the GI tract, the lactic acid bacteria (LAB), and these studies have revealed the presence of Carnobacterium, Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, Streptococcus, Vagococcus, and Weissella. Identification of LAB in

Marine and freshwater spawning environments present fish sperm with unique challenges, but for both, gametes often signal prior to contact via biochemical interactions through maternally-derived compounds (i.e. eggs and ovarian fluid; OF). For example, when OF is incorporated into the fertilization environment, sperm have been observed to exhibit changes in swimming trajectories (e.g. motility and

Olive flounder (Paralichthys olivaceus) also referred to as bastard halibut is a marine carnivorous species with great commercial value. The production of olive flounder has been dominated by aquaculture with 43 thousand tons of production in 2017 compared to fisheries with only 10 thousand tons in the same year. But despite the high market demand for this species, aquaculture production has not increased

Aquaculture offers a promising source of economic and healthy protein for human consumption and improved wellbeing. This has led to the development of the aquaculture industry, led through advanced production technologies and culture systems in many parts of the world. The intensification of fish production systems by farmers to meet consumer’s needs, as well as to generate increased profits, creates

Shrimp aquaculture in India has an extensive history of successes and challenges reflecting both the potential and the problems of developing this industry. The industry initially grew rapidly during the 1990s, largely through the efforts of individual farmers, but operated in an environment where there was often a lack of adequate regulatory guidance. During this time the total area occupied by farms

Recent studies have shown that coastal and shelf cephalopod populations have increased globally over the last six decades. Although cephalopod landings are dominated by the squid fishery, which represents nearly 80% of the worldwide cephalopod catches, octopuses and cuttlefishes represent ∼10% each. Total reported global production of octopuses over the past three decades indicates a relatively steady
