“…Plastic bags were noted to be more commonly used for the short-distance transport of a small volume of fish. This aligns with the literature from outside of China, which notes that market-sized fish are often transported in truck-mounted, high volume tanks over long distances [4,55], while smaller fish, such as juveniles and fingerlings, or some ornamental fish of high value, are transported in plastic bags [6,7,38,56].…”

“…For instance, rainbow trout spend a longer time at the bottom of the tank, occupy a smaller number of tank sections, reduce swimming activity, and increase the number of abnormal movements after experiencing transport stress [ 63 ]. Variatus platy ( Xiphophorus variatus ), an ornamental fish, show increased occurrence of biting and freezing behaviors post-transport, which may increase the risk of injury [ 56 ].…”

China is the largest food fish producer in the world. Chinese consumers normally purchase fish that are still alive to ensure freshness. Therefore, the live transport of fish is important in China’s aquaculture, although it carries potential risks for animal welfare. This study investigated the attitudes and knowledge of stakeholders within Chinese aquaculture towards the live transport and welfare of fish. Semi-structured interviews were conducted with 12 participants who were involved with the aquaculture industry in China. Most participants self-rated their transport-related knowledge as moderate and had some understanding of animal welfare, although this term was generally considered only relevant to terrestrial animals. Participants’ responses indicated that the live transport of fish occurs frequently in China, generally using sealed tanks, plastic bags, and foam boxes, in purpose-built vehicles. Seasonal changes, such as changes in ambient and water temperature, are considered to be important contributors to successful live transport, as well as sufficient oxygen supplies and stocking density. The use of anesthetics was not commonly reported, particularly in food fish, and fish capture is predominantly by conventional dipnets. The health status of transported fish is determined mostly by morphology (body injury, body or eye color, and fin condition), as well as vigor and swimming ability. Our results indicate that live transport poses a number of welfare risks to fish but that participants in the process associated welfare concerns more with terrestrial animals, not fish.

“…The physical and chemical properties of the water are also crucial, where water quality parameters such as dissolved oxygen and pH can impact stress and affect the underlying physiology, behaviour and ultimately welfare of fishes (Huntingford et al ., 2006; MacIntyre et al ., 2008; Stevens et al ., 2017; Williams et al ., 2009). Fishes exposed to even relatively short fluctuations in water quality in confinement showed behavioural changes with associated welfare implications (Vanderzwalmen et al ., 2021). As such, water quality parameters are frequently well reported in studies of enrichment, but not to the same level across studies.…”

Physical enrichment research for captive fish: Time to focus on the DETAILS

Growing research effort has shown that physical enrichment (PE) can improve fish welfare and research validity. However, the inclusion of PE does not always result in positive effects and conflicting findings have highlighted the many nuances involved. Effects are known to depend on species and life stage tested, but effects may also vary with differences in the specific items used as enrichment between and within studies. Reporting fine‐scale characteristics of items used as enrichment in studies may help to reveal these factors. We conducted a survey of PE‐focused studies published in the last 5 years to examine the current state of methodological reporting. The survey results suggest that some aspects of enrichment are not adequately detailed. For example, the amount and dimensions of objects used as enrichment were frequently omitted. Similarly, the ecological relevance, or other justification, for enrichment items was frequently not made explicit. Focusing on ecologically relevant aspects of PE and increasing the level of detail reported in studies may benefit future work and we propose a framework with the acronym DETAILS (Dimensions, Ecological rationale, Timing of enrichment, Amount, Inputs, Lighting and Social environment). We outline the potential importance of each of the elements of this framework with the hope it may aid in the level of reporting and standardization across studies, ultimately aiding the search for more beneficial types of PE and the development of our understanding and ability to improve the welfare of captive fish and promote more biologically relevant behaviour.

“…Aquarium fish is a popular hobby of growing interest worldwide, which has resulted in the expansion of trade of diverse ornamental fish species in more than 125 countries (Dey, 2016). It was estimated that over 2 billion live ornamental fish are transported annually, with trade shown for over 50 exporting countries and over 75 importing countries (Vanderzwalmen et al, 2021). More than 4500 species of freshwater ornamental fish and 1450 species of marine fish were recorded for trade, with a value of US$ 800 million to US$ 30 billion per year (Stevens et al, 2017).…”

Toxicity, physiological, histopathological, handling, growth and antiparasitic effects of the sodium chloride (salt) in the freshwater fish aquaculture

This paper provides the currently available knowledge in the literature regarding the use of sodium chloride (NaCl) in freshwater fish aquaculture and aquaria as related to toxicity, growth performance, transportation, physiology, immunity, histomorphology and antiparasitic treatment. This review assessed and discussed all of these factors, as well as the potential strategies available to be used in fish farming. Acute toxicity to NaCl varies widely among fish species (3.5-150.0 g L −1 ) depending on some environment factors, and many fish species are sensitive to concentrations near those required for their development, growth or for controlling and treating parasites. Acute exposure to NaCl may lead to mortality in different fish species, cause changes in feeding and swimming behaviour, as well as in growth performance and histomorphology of gills, while sublethal concentrations are less harmful. To reduce stress during transport of freshwater fish, concentrations of 1.0-10.0 g L −1 of NaCl in water have been tested for some fish species. Data have shown that survival, body growth of fish, food intake and stimulation of food conversion are affected by the NaCl concentration.Moreover, the effects of NaCl on the immune system, physiology and behaviour must also be considered. Sodium chloride may be a chemotherapeutic for controlling and treating ectoparasite diseases in farmed freshwater fish because of its effectiveness and low cost, but this compound may not be used in high or extreme toxic concentrations, since the maximum tolerance may be near the therapeutic doses. Therefore, this chemical product should be used with parsimony in fish farming. K E Y W O R D Saquaculture, blood, fish, growth, parasites, treatment | ACUTE TOXICITY OF NaCl IN FRESHWATER FISH SPECIESKnowledge on the tolerance limits of freshwater fish to NaCl is of ecological significance in assessing fish distribution and their impact on ecosystems, as well as for management practices in fish farms.The most common laboratory measure of NaCl tolerance is the concentration that is lethal to 50% of individuals (LC 50 ) over periods of 24-96 h. Such determinations are experimental and establish a causal link between the salinity and mortality. Some species of freshwater fish tolerate high concentrations of NaCl for longer periods when compared with other freshwater fish species (Table 1), and concentrations may be near the lethal concentration for the fish species. However, they lack consideration of other changes in the water quality that may occur with an increased salinity. Thus, it is necessary to know beforehand the mean lethal concentration (LC 50 ) for each species of fish as well as the environmental conditions for exposure to NaCl.How to cite this article: Tavares-Dias, M.
