On the basis of the findings, <i>C</i>. <i>carpio</i> can be classified as a detri-omnivore, as it consumes benthic species like nematodes, ostracods and insect larvae. Seasonal fluctuations in food item consumption were noted (<i>p</i> &lt; 0.05), with higher intake during the rainy season and reduced consumption in the dry season. There was a distinct ontogenetic shift in the relative importance of food items and showed significant variations in food preferences among size groups (<i>p</i> &lt; 0.05). The contributions of animal-origin food categories (ostracods, zooplankton and insects) were important in the diet of the smaller size class, whereas food of plant origin (macrophytes) and detritus were more important in the diet of adults.

The aim of this study was to investigate the effects of TBT, TPT, and SnCl₂ on the embryonic development of zebrafish. In this study, zebrafish embryos were used to observe the acute toxicity of TBT, TPT, and SnCl₂. Fish embryo toxicity analysis was performed for different TBT, TPT, and SnCl₂ concentrations (1, 5, 10, 15, and 20 ng/L). Fertilized eggs in 24-well plates (20 eggs in each concentration) were incubated at 26°C for 4 days, and embryo clotting, embryo heartbeat, and morphological abnormalities were recorded after 96 h. Coagulation increased significantly in a dose-dependent manner, and TBT was able to induce coagulation in zebrafish embryos. Heartbeat changes significantly decreased (<i>p</i> &lt; 0.05) in a dose-dependent manner at different TBT doses (<i>p</i> &lt; 0.05). The percentage of mortality was higher in embryos at trace levels of TBT, indicating that the embryos are more sensitive to the toxicity of TBT. TBT is therefore extremely toxic and can have fatal consequences for zebrafish embryos, ultimately leading to the extinction of species and a decline in biodiversity in the aquatic environment.

Off-flavours often give fish earthy, muddy, or other undesirable flavours. Typically, off-flavours are removed during a depuration period in which fish are fasted and held in clean water. Unfortunately, this causes additional costs and delayed sales, while fish lose weight and show a decrease in lipid content. First, we studied fish growth in a partial RAS (PRAS) where the conditions are very similar to those in depuration with a water exchange rate of 4000 L kg⁻¹ feed, compared to RAS with a 650-L water kg⁻¹ feed. Rainbow trout (<i>Oncorhynchus mykiss</i>) was reared in both systems. Our aim was to combine the benefits of a higher water exchange rate: the lack of need for biofilters and a lower accumulation of off-flavours while obtaining stable rearing conditions. Additionally, we studied the effects of moderate feeding and H₂O₂ addition during depuration. The fish grew faster in a PRAS than in a RAS when fed ad libitum. Thirteen off-flavour compounds were found in the fish flesh and 11 in the circulating water. The H₂O₂ addition led to decreased levels of off-flavours in the tank water and in fish muscle. The results showed no significant differences in off-flavours between the fed and not-fed systems, showing that moderate feeding did not prevent a good depuration result. However, the lipid content and the overall fish weight were higher in the fed systems, which suggests more effective depuration. Increased depuration efficiency can be an important tool when considering ways to improve the profitability of production.</p>","PeriodicalId":100114,"journal":{"name":"Aquaculture, Fish and Fisheries","volume":"4 5","pages":""},"PeriodicalIF":1.1,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aff2.70004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142429399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the capacity of juvenile green-lipped mussels (GLMs) (<i>Perna canaliculus</i>) to uptake and assimilate dissolved glucose at five experimental concentrations (i.e. 10 µg mL⁻¹, 100 µg mL⁻¹, 1 mg mL⁻¹, 10 mg mL⁻¹ and 30 mg mL⁻¹) as a supplement to cultured microalgae. Growth and survival of the mussels were measured over 3 weeks. Although all glucose concentrations improved the performance of mussel spat compared to the control, the best performing was a concentration of 1 mg mL⁻¹ of dissolved glucose which enhanced daily spat growth 2.7 times that of the control live microalgal diet without glucose. Survival was high (i.e. &gt;95%) for all treatments except for the highest experimental concentration of glucose, for which a concentration of 30 mg mL⁻¹ resulted in mean mortality of 24%. Mussel spat supplemented with dissolved glucose accumulated up to 30% greater lipid and improved the carbohydrate content per mg g⁻¹ of ash-free dry weight as much as 3.5 times compared to those in the control treatment, indicating that they were in greater nutritional condition. This demonstration that dissolved glucose can be used to fuel growth by GLM spat at concentrations as low as 10 µg mL⁻¹ suggests that other soluble nutrients may also act as a supplemental feed for cultured juvenile molluscs. Dissolved nutrients have the potential to improve the performance of spat in nursery systems while simultaneously reducing the reliance of cultured microalgae as a sole feed input.</p>","PeriodicalId":100114,"journal":{"name":"Aquaculture, Fish and Fisheries","volume":"4 5","pages":""},"PeriodicalIF":1.1,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aff2.70001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142152140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six acoustic receivers were deployed in the fjord and a river, which flows into the upper reaches of the fjord, with the aim of detecting 20 sea trout that had been tagged with acoustic transmitters. Sea surface temperature and winds (east–west) affected movement patterns of the sea trout the most, while changes in atmospheric pressure were also important, but to a lesser extent. Sea surface temperature and atmospheric pressure both had a positive relationship with the number of detections, whereas stronger winds from the east (i.e. from land) resulted in more detections than stronger winds from the west (i.e. from the ocean). In addition, interesting diel (day–night) movement patterns were observed for some fish. A significant positive correlation was also discovered between the weight of the fish and the number of detections.

The analysis utilises machine learning algorithms to extract consumer sentiments, opinions, and demands from online chatter from different online domains. The online sentiments are determined as positive, negative, or neutral based on their word choice, tone, and context. The information provided gives insights into perception, which is valuable information for oyster producers, seafood industry stakeholders, and marketers to identify consumer preferences and formulate appropriate strategies accordingly. The results suggest that while farmed oysters are gaining popularity, there are still some concerns and criticisms around the industry. Positive words associated with mentions of oysters in general include ‘great’, ‘love’, ‘delicious’, ‘enjoyed’, and ‘oyster bar’, while negative words associated with oysters include ‘water’, ‘raw oyster’, ‘bad’, and ‘not eat’.

While we aim to keep an open-minded approach with Underwater Notes, we are not simply looking for validation studies or corroborative reports.
