Latest Mediterranean Aquaculture News: Business, Tech & Science

CLIMATE CHANGE | PRODUCTION

Extreme summer tests the productive limits of Italian aquaculture

Verona, Italy, 4/09/2026 | Heat and lower oxygen availability reduce estimated trout production by 15% and cause massive mussel mortalities that also jeopardise upcoming production cycles.

HEALTH | ANTIPARASITICS

Fight against gilthead seabream parasite Sparicotyle finds candidates more potent than praziquantel

Castellón, Spain, 3 September 2026 | CSIC researchers identify a molecule with in vitro parasiticidal activity more than 11,000 times greater than that of praziquantel

HEALTH | FUNCTIONAL NUTRITION

Why plant-based additives do not offer universal disease protection in trout

A trial using fenugreek, bay leaf and black mustard extracts found that immune and survival responses varied according to the additive, dose and bacterial pathogen, without significantly improving growth or feed conversion

WELLBEING | TRANSPORTATION

Fish transport requires density, water conditions and temperature to be adapted to each species and journey

A review concludes that there is no universal solution for reducing stress and places the control of oxygen, temperature and metabolites ahead of additives, anaesthetics and other specific measures

MACROALGAE | CULTIVATION

Kelp nurseries may need to expose seedlings to stress to preserve production performance

A review proposes combining stricter broodstock selection with controlled exposure to heat, low salinity or nutrient limitation, although the strategy still requires validation under commercial farming conditions

CLIMATE | WATER SECURITY

Drought turns access to water into a production risk for European freshwater aquaculture

Hungary, 1 September 2026 | Fish deaths and dried-out ponds in Hungary, alongside emergency measures in several Central and Eastern European countries, show that water availability is becoming a strategic constraint for freshwater farming

INVESTMENT | HATCHERIES & RAS

Marine hatcheries as a key to aquaculture business success

Biosecurity established as the most cost-effective health investment in crustacean aquaculture

Global, 31/08/2026 | Global consultation by WOAH and STAR IDAZ ranks prevention, water management and good practice ahead of vaccines, probiotics and treatments as priorities for reducing the impact of disease

HEALTH | PROBIOTICS

Farming system shapes probiotic efficacy in tilapia

28 August 2026 | A meta-analysis of 141 studies identifies probiotics as the most consistent strategy for improving growth and feed conversion, but warns that production-environment stability influences the reproducibility of results

RAS salmon starts to reveal its real production costs in China

China, 28 August 2026 | Nordi Aqua lowers the cost of salmon produced in recirculating aquaculture systems to EUR 6.05/kg, but has yet to achieve a positive margin

ANALYSIS | NUTRITION

Higher dietary EPA and DHA levels linked to lower mortality and improved feed conversion in salmon

Norway, 26 August 2026 | An analysis of more than 430 million fish associates levels above 9% of total fatty acids with better and more predictable production outcomes, although the observational study cannot demonstrate causality

INVESTMENT | HATCHERIES & RAS

Marine hatcheries as a key to aquaculture business success

Global, 31 August 2026 | A commercial marine fish hatchery requires a multi-million-euro investment, but the real challenge is not only financial: species biology, biosecurity, energy and water-system design will shape production costs and juvenile quality for years to come

ANALYSIS | AQUACULTURE NUTRITION

Can hydrolysates improve aquafeeds without increasing the cost of the fish produced?

Global, 3 August 2026 | The industry is investing in converting by-products into functional ingredients capable of supporting feed intake, digestibility and the performance of diets containing less fishmeal, although public data demonstrating their profitability over an entire production cycle remain scare

NUTRITION | AQUAFEEDS

EU protein plan opens opportunities for aquafeeds but leaves the sector outside its core measures

Brussels, 13 July 2026 | The European strategy could increase the availability of local and circular ingredients, but it does not guarantee that aquaculture will gain access to cheaper proteins

Science-to-business | FEEDS

Microalgae in aquafeeds: how much can realistically be included and what return can farmers expects?

Luxembourg, 3 July 2026 | In terms of total inclusion, the European Commission considers technically feasible ranges of 10% to 15% algae-based ingredients in salmon and trout feeds, and 20% to 25% in feeds of European seabass and gilthead seabream.
