"Emerging Contaminants in Aquaculture Production: Environmental and Human Health Risks" (Aquaculture Journal), evaluates the impact of Emerging Contaminants (ECs)—such as microplastics, pharmaceuticals, and industrial chemicals—on aquaculture systems.

The review synthesizes data from 137 studies to examine how direct chemical use and surrounding industrial activities introduce persistent pollutants into farmed aquatic environments. Findings highlight that ECs bioaccumulate within the tissues of commercial aquatic organisms, posing human health risks through seafood ingestion. Simultaneously, contaminated aquaculture effluents degrade surrounding aquatic ecosystems and water quality.

To address these environmental and public health concerns, the authors emphasize the need for enhanced monitoring methodologies, stricter regulatory frameworks, and sustainable management technologies. Recommended solutions include recirculating aquaculture systems (RAS), advanced oxidation processes, and targeted strategies to reduce microplastic and antibiotic pollution.

The findings from the MDPI study demonstrate that environmental conditions at harvest—specifically seawater temperature—directly govern post-mortem muscle breakdown in Mediterranean-farmed fish (Sparus aurata, Dicentrarchus labrax, and Pagrus major), dictating shelf life and fillet quality. Counterintuitively, peak proteolytic activity across key enzymes (calpain, collagenase, cathepsin B, and cathepsin L) occurs not during extreme winter cold or summer heat, but during transitional moderate-temperature seasons like spring and mid-autumn, rendering fish harvested in these windows particularly vulnerable to accelerated flesh softening and muscle gaping.

To mitigate this seasonal risk, commercial aquaculture operations and quality control teams must adapt their post-harvest logistics around a distinct two-phase enzymatic degradation timeline. The early phase (Days 0 to 5) is driven by calpain and collagenase attacking structural proteins and connective tissue, which requires immediate post-slaughter sub-zero cooling via optimized ice-slurry systems and pre-harvest stress reduction to suppress early loss of firmness. In contrast, late-phase degradation (Days 5 to 13) is governed by lysosomal cathepsins released as cell membranes rupture, necessitating targeted preservation technologies—such as sub-chilling (-1°C to -2°C), modified atmosphere packaging (MAP), or natural enzymatic inhibitors—for products intended for extended retail display or long-distance cold chains. Because baseline enzymatic rates and responses vary significantly across S. aurata, D. labrax, and P. major, producers must replace "one-size-fits-all" processing with species-specific harvest calendars, chilling ramps, and shelf-life expectations, prioritizing moderate-temperature harvests for rapid local distribution or secondary processing where soft texture is less critical.

A 2026 study published in Aquaculture Research🔬 evaluated the impact of enriching a traditional rice bran-based biofloc system with the marine diatom Halamphora coffeaeformis( 1×10^5 cells/mL) on Black Tiger Shrimp🦐 (Penaeus monodon) postlarvae.

The researchers found that the microalgae supplementation effectively bridged critical nutritional gaps in standard biofloc, boosting essential omega-3 polyunsaturated fatty acids like EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) while increasing overall lipid and protein retention in the shrimp.

Consequently, the enriched group achieved significantly higher final body weight, faster daily weight gain, and an improved Feed Conversion Ratio alongside overall survival rates exceeding 95%.

Furthermore, when challenged with Vibrio parahaemolyticus, the pathogen behind AHPND ( Acute Hepatopancreatic Necrosis Disease) /EMS ( Early Mortality Syndrome), the enriched postlarvae exhibited marked disease resistance with a reduced mortality rate of 64.5% and substantially less damage to their hepatopancreas.

Overall, integrating H. coffeaeformis into biofloc systems provides a sustainable aquaculture strategy to cultivate healthier, faster-growing, and more pathogen-resilient shrimp.

Transgenic Live Feed for Antiviral Protection in Shrimp*: Viral pathogens like Covert Mortality Nodavirus (CMNV) cause severe losses in Penaeus vannamei aquaculture. Because shrimp lack adaptive immunity, traditional vaccines fail. While RNA interference (RNAi) can block viral replication, naked RNA breaks down rapidly in water.

To solve this, researchers engineered the marine rotifer (Brachionus plicatilis)—a standard live feed—to deliver antiviral short hairpin RNA (shRNA). Using a piggyBac transposon system, CMNV-specific shRNA was integrated into the rotifer genome for stable, heritable expression.

As post-larvae graze on rotifers, the antiviral shRNA is naturally delivered via daily feeding without stress.

Key Results:

Viral Suppression: qPCR confirmed a significant drop in CMNV viral load.

Higher Survival: Shrimp exhibited markedly lower mortality under viral challenge.

Safe Growth: Zero adverse effects on growth or behaviour.

This turns standard hatchery feed into a bio-secure, non-invasive prophylactic tool against shrimp viruses.

Microbiome engineering in aquaculture is transforming the way we manage aquatic health and productivity.

It focuses on harnessing beneficial microorganisms to create a balanced and healthy farming environment.
These microbes play a key role in improving digestion, nutrient absorption, and overall fish growth.
By strengthening immunity, they help reduce disease outbreaks and mortality rates.

This approach also minimizes the need for antibiotics and harmful chemicals.

Healthy microbial communities contribute to better water quality by breaking down waste and toxins.
They support sustainable aquaculture practices with lower environmental impact.

Applications include probiotics in feed, biofloc technology, and water treatment systems.
Farmers can achieve higher yield and better feed conversion efficiency.
It also ensures safer and higher-quality seafood for consumers.

Microbiome engineering is a science-driven solution for modern aquaculture challenges.
It promotes eco-friendly farming while maintaining economic profitability.
With ongoing research, more targeted and effective microbial solutions are emerging.

Adopting this technology can lead to long-term farm sustainability.
Small microbes truly make a big difference in aquaculture success.

Imagine a farm where waste becomes nutrition.
That’s the power of Biofloc Technology (BFT).
Microorganisms recycle waste into useful biomass.
This keeps water clean and healthy for shrimp.
It reduces environmental impact significantly.
At the same time, it boosts productivity.
Less waste, more efficiency, better profits.
The future of shrimp farming is here. 🦐
