Summary: The present study found that rearing low-quality juveniles of the lined seahorse in green water or under lower light intensities (200-500 lx) can improve their survival and growth. Overall, juveniles in green water had better survival rates and growth compared to those in clear water. Similarly, low light intensity (200-500 lx) also significantly improved the survival and growth of low-quality juvenile seahorses.

Summary: The feeding experiment showed that dietary supplementation of lutein at levels between 62.5 to 75 ppm resulted in similar growth performance, antioxidant capacity, and immunity in Litopenaeus vannamei compared to dietary astaxanthin. These results suggest that a dose of 62.5-75 ppm of lutein is suitable for replacing astaxanthin in the diet of L. vannamei.

Summary: The seahorse is a typical suction feeder that captures prey mainly based on the visual system. The feeding process of juvenile seahorses can be divided into four steps, and as they mature, the attack distance, snout width, capture success rate, and food intake all increase. There is a significant turning point in the expansion rate of the snout, successful predation rate, and growth rate around 10 days after parturition.

Summary: In this study, the effect of dietary astaxanthin on the growth, antioxidant system, and reproductive development of female Nile tilapia was evaluated. The results showed that 150 mg/kg dietary astaxanthin promoted growth, increased antioxidant capacity, stimulated gonad development, and improved oocyte development.

Summary: This study found that astaxanthin can improve the stability of DHA-enriched egg products during storage, primarily by suppressing the oxidation of DHA-non-esterified fatty acids and minimizing the degradation of DHA.

Summary: Astaxanthin (Ax) and lutein are important fat-soluble pigments and essential nutrients for human and animal health. This review focuses on the commercial production of Ax and lutein, their effects on yolk color and nutritional functionality, and their enhancement of immune function. The potential roles of carotenoids in the cytokine storm and gut microbiota are also briefly presented, along with suggestions for future research.

Summary: The study analyzed the impact of acute temperature challenge on juvenile seahorse growth by examining external behavioral and internal physiological, biochemical, and genetic indicators. The results showed significant changes in external indexes after 12 hours of temperature challenge, indicating a potential suppression of juvenile growth. Biochemical indicators and certain functional genes were found to be correlated with feeding behavior parameters, providing valuable information for understanding the effects of short-term temperature challenges on juvenile seahorses.

Summary: This study investigated the characteristics of egg consumption and the production of functional eggs in China. It found that pink eggs were the most popular and most consumers preferred eggs weighing 48-58 grams. Functional eggs had low awareness among Chinese consumers. Based on the survey results, the researchers produced small, pink functional eggs that met the preferences of Chinese consumers through a specific diet.

Summary: The increasing seawater temperatures in Tasmania during the summer period have led to thermal stress-induced starvation events in farmed Atlantic salmon, resulting in flesh pigment depletion. In this study, the effect of prolonged exposure to elevated water temperature on flesh pigmentation and muscle structural integrity was investigated using histological and transcriptomic analysis. The results showed that muscle degradation and atrophy were observed in fish with low flesh pigmentation, while genes related to metabolism and muscle integrity were differentially expressed in fish with high flesh pigmentation.

Summary: This study investigated the effects of dietary astaxanthin on fish growth and body coloration. The results showed that the group supplemented with astaxanthin had higher skin redness and yellowness, as well as higher concentrations of astaxanthin and lipoproteins. Differentially expressed genes involved in carotenoid deposition were identified, suggesting their association with skin coloration.

Summary: Photo-identification has been successfully used as an individual recognition tool in seahorse species, especially in this study where a pattern recognition algorithm was employed to identify short-snouted seahorses based on differences in coronet shapes. The method showed promising results in identifying captive-bred seahorses, with high matching rates for both young adults and adults, indicating its potential for population size estimates in the wild.

Summary: The study found that the long-snouted seahorse population in Ria Formosa did not lose genetic diversity from 2001 to 2013, and no genetic bottleneck was detected. However, there was an increase in overall relatedness, raising concerns about potential future inbreeding. The effective population size seemed to approach the necessary threshold for retaining evolutionary potential, but the impact of sample size on these results is unclear.

Summary: Seahorses are facing numerous anthropogenic pressures worldwide, and a forensic tool to identify their geographic origin can contribute to combating illegal capture and trade. The elemental fingerprints of seahorse bony structures can successfully confirm their geographic origin, enhancing traceability in the trade of these endangered fish.

Summary: This study investigates the fatty acid profiles of cultured European short-snout seahorses to assess their nutritional value and intraspecific variation. The results suggest that male seahorses have a more suitable fatty acid profile for human nutrition compared to females. The fatty acid composition of seahorses aligns with the traditional beliefs in Traditional Chinese Medicine, but only seahorses from sustainable sources should be traded, and the conservation of wild populations should be a global priority.

Summary: In the face of future ocean warming and habitat fragmentation, coastal fishes, including seahorses, need to adjust their physiological and behavioral traits. This study investigated the behavior of two sympatric seahorse species and found that seahorses have behavioral tolerance to temperature variation. However, increased density of one species and habitat availability can affect the behavior of the other species, potentially impacting their distribution in shallow habitats.
