Summary: The aim of this study was to explore the development of off-odors in fish oil from the perspective of fatty acid oxidation. It was found that oxidation of fatty acids other than DHA and EPA also contribute to the off-odors in fish oil. The off-odors of fish oil were successfully simulated by combining oxidized samples of DHA, EPA, and sunflower oil. A novel analytical approach using GC-IMS and OPLS-DA was applied to identify differences in volatile components between recombinant oil and fish oil.

Summary: Microalgal oils have emerged as a sustainable alternative to fish oil and nutritionally poorer vegetable oils for aquaculture species like gilthead seabream. Incorporating microalgal oils in the diet of seabream resulted in maintained fish performance, lower contamination levels in fillets, and similar sensory quality compared to diets rich in fish oil. This offers a more resilient means for sustaining the future growth of seabream aquaculture.

Summary: The study found that DHA-acylated AST diesters significantly alleviated nephrotoxicity by improving kidney function and reducing pathological damage and oxidative stress. Dietary DHA-acylated AST esters inhibited the activation of the caspase cascade and MAPKs signaling pathway and decreased pro-inflammatory cytokine levels. These findings suggest that DHA-acylated AST esters could potentially be a novel therapeutic candidate or adjuvant for alleviating acute kidney injury.

Summary: An PreIS-HILIC-MS method was established to specifically and selectively screen PLEPA/DHA in different fish oil samples, including saury, grass carp, hairtail, and yellow croaker. The method demonstrated high sensitivity, good linearity, and suitability for quantitative analysis of PLEPA/DHA in fish oil samples, with the ability to identify and quantify 24 different compounds. The performance of this method was compared with traditional full-scan mode and showed unique superiority in targeted screening of PLEPA/DHA in fish oils.

Summary: Research suggests that LPC-DHA/EPA-enriched krill oil can increase brain DHA and improve memory-related behavior in mice with the APOE4 gene. Therefore, long-term use of LT-krill oil supplements may provide some level of protection against age-related neurodegeneration.

Summary: Natural astaxanthin is richer than synthetic astaxanthin, but cultivating it in photobioreactors is expensive and downstream processing techniques for solubilization are not cost-effective. As a result, the cost of astaxanthin is high, leading pharmaceutical and nutraceutical companies to opt for synthetic astaxanthin. This review discusses the chemical character of astaxanthin, more cost-effective cultivating techniques, and its bioavailability. Moreover, the antioxidant properties of this microalgal product against various diseases are discussed, which make it a promising drug for reducing inflammation and its consequences.

Summary: The study found that supplying diets containing Shizochytrium sp microalgae meal for 49 days is sufficient to increase the omega-3 content, particularly DHA, in Nile tilapia fillet without affecting other parameters. Additionally, residues such as the head, spine and viscera benefit from an increase in omega-3 and DHA content from the feeding period.

Summary: The study assessed the proximate and sterol composition of different macroalgae species and seagrass over 3 years in a subtropical climate. Each macroalgae species had a distinct sterol composition typical of their taxonomic group. The seasonal and interannual variations in sterol composition were relatively stable, except for a few exceptions likeG. sjoestedtiisampled in August andU. lactucaandP. torreyiboth sampled in May 2002.

Summary: This study on Pacific red snapper spawns during lecithotrophic development found that hatching rates were higher from pond spawns compared to wild spawns, and embryos with higher ARA proportions and higher EPA:ARA and DHA:ARA ratios in egg phospholipids had better survival rates at 48 hours. The analysis suggests that subtropical L. peru requires less DHA and more ARA and monounsaturated fatty acids in their diet, compared to temperate marine fish.

Summary: Increasing CO2 emissions have led to changes in oceanic pH levels, which have a significant impact on phytoplankton growth and composition, particularly diatoms. A low-cost pH Stat system was designed and evaluated for regulating the pH levels in multiple cultures simultaneously. The results showed that higher pH levels promoted nitrate consumption and growth rates, while lower pH levels had unfavorable effects on diatom acclimation and growth.

Summary: This study evaluated the use of canary seed and giant kelp seaweed as ingredients for Nile tilapia feed. The results showed that fish fed canary seed and kelp seaweed diets (100 and 200 g/kg) had similar weight gain to those fed the control diet, while the 300 g/kg diets decreased growth performance. Digestibility trial results indicated that canary seed had higher nutritional value than kelp seaweed for Nile tilapia.

Summary: Lipid oxidation in feeds can negatively affect the health and rearing performance of juvenile marine fish. Increasing intake of oxidized lipids decreases survival, growth rate, and liver metabolism, while also altering lipid metabolism and blood cell fragility. These results indicate the importance of proper handling and storage of feeds to maintain their nutrition quality.

Summary: This study evaluated differences in trace and macro element content in red crabs between years with and without El Nino conditions. It also assessed the composition of these elements between different sites along the Baja California Peninsula and the potential risk to human health from consuming red crabs. Significant differences were found in the content of these elements, mainly due to environmental variables that influence the vertical distribution of red crabs. The contribution of these elements to human nutrition and their potential risk to health were also evaluated.

Summary: Saltwater intrusion into groundwater systems is a global problem caused by activities such as groundwater overexploitation and climate change. The coastal Los Planes aquifer in Baja California Peninsula, Mexico, has been affected by seawater intrusion due to excessive groundwater exploitation for over 40 years. A dataset of 55 samples, including 18 samples from campaigns between 2014 and 2016, was compiled. Various methods were used to assess the impact of seawater in the coastal aquifer, with reasonable results obtained for most of the area. However, in the northwestern part of the aquifer, samples from hydrothermal wells were not recognized using these methods, indicating the influence of thermal water and direct mixing with seawater.

Summary: Research in Mexico evaluated the astaxanthin content in the head and shell of various commercial shrimp species, finding that white shrimp had the highest levels of astaxanthin in the head, while shrimp farmed under hyper-intensive conditions had the lowest levels. Shrimp by-products were shown to be a suitable source of astaxanthin, except for those farmed under hyper-intensive conditions.
