Insect meal does not penalise gilthead seabream growth, but profitability remains the key challenge

Messina, Italy, 6 July 2026 | Defatted Hermetia illucens meal can be incorporated into commercial diets for gilthead seabream without compromising growth, feed conversion or the nutritional composition of the fillet.

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.

SHRIMP FARMING | SCIENCE

Genetics, water quality, microbiota, nutrition, management and biosecurity define shrimp farming research

Kuala Nerus (Malaysia), 3/07/2026 | A historical review of 10,896 scientific publications on shrimp and prawn aquaculture, published between 1970 and 2024, reads like a strategic map of how the sector’s scientific priorities have evolved

FISH HEALTH | VACCINATION

Why a vaccine that is effective in the laboratory can fail on a fish farm

Global, 2 July 2026 | The future of fish vaccines is about applying them better, measuring them better and understanding the conditions that make real and durable protection possible

MICROALGAE | ASTAXANTHIN

Residual CO₂ from RAS can boost natural astaxanthin production with microalgae

Finland, 2 July 2026 | A Finnish study with Haematococcus pluvialis shows improvements in growth biomass and astaxanthin production when using degassing air and effluent water from recirculating aquaculture system, although scalability remain to be demonstrated

INTERVIEW

The importance of trial units at BioMar’s R&D centres for the development of efficient and profitable aquafeeds

Iannis Karacostas explains to misPeces how trial units help refine the nutritional requirements of species such as European sea bass, gilthead sea bream and rainbow trout, with the aim of improving growth, feed conversion, product cost and profitability for producers

CLIMATE CHANGE | RESILIENCE

Not all alternative diets prepare gilthead seabream in the same way for Mediterranean warming

Castellón, Spain, 1 July 2026 | A study by IATS-CSIC shows that feeds based on alternative raw materials can sustain productive performance, although each formulation activates different physiological responses to stress and seasonal adaptation

TECHNOLOGY | FISH BEHAVIOUR

Precision feeding is beginning to interpret fish behaviour during production

NUTRITION | LIVE FEED

Copepods versus rotifers: why the future of many hatcheries may be decided in the first weeks of life

Global, 30 June 2026 | The real debate between copepods and rotifers is not about replacing one live with another, but about when a more complex and nutritious prey can justify the use of a feed that is harder to produce

NUTRITION | ALTERNATIVE RAW MATERIALS

Fermented vegetable by-products in tilapia feeds: stable growth, positive intestinal signals and commercial caution

SEAWEED | CARRYING CAPACITY

Seaweed farming in Europe needs to know how far it can grow without losing profitability, social licence or ecological capacity
