Article Synopsis
  • The study examined how different microalgae diets affect the growth and survival of a specific marine species, with results indicating significant variations based on the diet.
  • The fastest development and highest survival rate (14 days and 17.6%) were observed with one type of microalgae, while the slowest and lowest survival (37 days and 6.40%) occurred with another.
  • Overall, specific growth rates and nauplius production were highest with the most effective microalgal diet, highlighting its importance in the development stages from nauplius to adult.

The ubiquitous proximity of the commonly used microplastic (MP) particles particularly polyethylene (PE), polypropylene (PP), and polystyrene (PS) poses a serious threat to the environment and human health globally. Biological treatment as an environment-friendly approach to counter MP pollution has recent interest when the bio-agent has beneficial functions in their ecosystem. This study aimed to utilize beneficial floc-forming bacteria Bacillus cereus SHBF2 isolated from an aquaculture farm in reducing the MP particles (PE, PP, and PS) from their environment.

Article Synopsis
  • The study investigates the antibacterial effects of phenolic extracts from marine and freshwater species, focusing on various strains of Gram-positive and Gram-negative bacteria.
  • Results show that filamentous species exhibited significantly higher antibacterial activity than their planktonic counterparts, with the strongest inhibition observed in filamentous species against specific Gram-positive bacteria.
  • The findings highlight the potential of these species to produce bioactive compounds for developing new antibiotics, benefiting both the aquaculture and pharmaceutical sectors.

Microplastics (MPs) occurrence in farmed aquatic organisms has already been the prime priority of researchers due to the food security concerns for human consumption. A number of commercially important aquaculture systems have already been investigated for MPs pollution but the mud crab (Scylla sp.) aquaculture system has not been investigated yet even though it is a highly demanded commercial species globally.

  • The experiment investigated the antioxidant content in guppy fish fed various diets with microalgae, replacing fishmeal, and its effects on water quality.
  • Fifteen guppy fries were kept in tanks with varying dietary inclusions (0%-15% microalgae) for 100 days, and water quality parameters were monitored throughout the trial.
  • Results showed that the microalgal diets significantly enhanced antioxidant levels in the guppies and improved water quality, suggesting benefits for both fish health and aquaculture practices.

Microplastics pollution has become a threat to aquaculture practices, as nearly all farming systems are saturated with microplastics (MPs) particles. Current research on MPs is limited considering their effects on aquatic organisms and human health. However, limited research has been conducted on potential cures and treatments.

Data of this article describes growth, survival rate, water quality and hemato-biochemical indices of Nile Tilapia () fry. To collect the data, the Nile Tilapia fry was reared in 30 L glass aquarium (18 fish/ tank) for 56-days under controlled environmental condition. Feed was prepared with 25 and 50% replacement of commercial fish meal with sp.

Article Synopsis
  • The study focused on the antioxidant properties of 26 tropical marine microalgae, identifying 10 strains with significant amounts of antioxidant compounds like carotenoids, phenolics, and fatty acids.
  • Various antioxidant assays (ABTS, DPPH, superoxide radicals, and nitric oxide scavenging) revealed that the antioxidant capacity of these microalgae differs based on species and growth phases, with carotenoids and phenolics being the key contributors.
  • Specific correlations were found between antioxidant capacity and the presence of certain compounds, such as fucoxanthin and β-carotene in some species during specific growth phases, highlighting the complex relationship between algae growth and antioxidant production.

We isolated fifty-two strains from the marine aquaculture ponds in Malaysia that were evaluated for their lipid production and ammonium tolerance and four isolates were selected as new ammonium tolerant microalgae with high-lipid production: TRG10-p102 Oocystis heteromucosa (Chlorophyceae); TRG10-p103 and TRG10-p105 Thalassiosira weissflogii (Bacillariophyceae); and TRG10-p201 Amphora coffeiformis (Bacillariophyceae). Eicosapentenoic acid (EPA) in three diatom strain was between 2.6 and 18.

The data collection was initiated to evaluate the effects of supplementary phospholipid to non-fishmeal based diet in order to make functional diets for the Malaysian Mahseer, . Four iso-nitrogenous and iso-lipidic diets were formulated to consist 100% fishmeal (FM100), 0% fishmeal or full fishmeal replacement (FM0), and 0% fishmeal supplemented with 4% phospholipids (FM0+4%PL), 6% phospholipids (FM0+6%PL). A 60-day feeding trial was conducted and data collection was carried out for the following parameters; growth indices, somatic parameters, whole body nutrient composition, muscle fatty acid composition, haematocrit value and serum lysozyme activity.

Microalgae are the major photosynthesizers on earth and produce important pigments that include chlorophyll a, b and c, β-carotene, astaxanthin, xanthophylls, and phycobiliproteins. Presently, synthetic colorants are used in food, cosmetic, nutraceutical, and pharmaceutical industries. However, due to problems associated with the harmful effects of synthetic colorants, exploitation of microalgal pigments as a source of natural colors becomes an attractive option.
