Feed for aquaculture

Innovative solutions for your species

Skretting has consistently developed innovative products and solutions that, over time, have evolved into production standards. Skretting feeds wholly meet the nutritional requirements of fish and shrimp throughout their lifecycle. Below, you can find a selection of our global product portfolio.

Catfish Essential

Essential is a catfish grower diet for normal farming conditions.

Essential consists of the same good quality raw materials as the other Skretting catfish grower diets. Essential is formulated to maximise protein efficiency as larger fish require lower protein levels for growth than smaller fish.

Feeding essential is easy and the experience from the market is that fish will have good growth and good FCR.

Catfish Fish Starter

Fish Starter is an excellent product to support a smooth transition between the high protein and fat levels of Gemma Wean and the catfish grower diets that are lower in protein and fat.

The product can be used when fry reach 0.3g. In this period fry are often transferred from small tanks to bigger tanks, to small ponds or to hapas in big ponds. Because these events are stressful, especially to younger fish, it is important to feed a diets that focuses on high survival and excellent growth.

Gradually changing to other life stage diets will minimise the risk of sudden feed intake reduction, supporting optimal fish growth, health and high survival rates.

Fish Starter 1.8mm is a floating micropellet that will train the fry to start feeding on floating feeds during the grower stage, Fish Starter is formulated according to the Protec principles.

Catfish Pelletized

Some farmers may favour traditional sinking diets as a result of their specific farming system. It is common to use these diets towards the end of the production cycle.

The pelletised diets can be fed to fish from 120g onwards.

Feeding pelletized feeds will lead to good growth rates but reaching target weights will take longer than when feeding Skretting’s extruded diets.

Pelletised diets show best performance in flow through systems with a high water renewal rate.

Catfish Superior

Currently the most popular grower feed for African catfish in Nigeria and other African countries is Skretting’s ‘Superior’ feed for catfish. Superior is a catfish grower diet for optimal farming conditions.

Extruded pellets are heated to much higher temperatures than pelleted feeds. High temperatures cause starch to gelatinise, creating a strong and water stable pellet.

The porous structure lowers the pellet density, allowing it to float. Another advantages of these pores is that the pellets can absorb more fat, making Superior the highest energy diet.

Catfish Superior Repro

Broodstock nutrition has a profound influence on the quantity, quality and performance of the offspring. Feeding Superior Repro ensures that eggs produced will contain sufficient energy to aid transition from endogenous to exogenous feeding in the catfish larvae.

Superior Repro is a floating diet especially designed for catfish breeders. The diet is formulated according to the Protec principles.


Each life stage has specific nutritional requirements. At Skretting, our R&D knowledge
enables us to provide precise nutrition for the various production stages. Trout have a larger protein requirement when the fish are small, and a lower requirement when the fish are larger.

Through extensive trials and research, we define the optimal protein level in the different feeds. We have shown that a lack of protein decreases performance, but excessive protein does not improve growth, is costly and increases the FCR.

For maximum muscle growth, the trout needs both protein and fat. Protein and energy builds the muscle, while part of the growth also comes from the build up of intramuscular fat, which provide us with the healthy fatty acids that salmonids are known for.

To help trout better utilise the fat in the feed, micro nutrients are added to improve the mobilisation of fat in the body. The result is less fat accumulation in the gut, and increased feed intake, growth and harvest yield.

Celero products are available with or without astaxanthine and with or without Protec
ingredients to support optimal fish health.

Gemma Wean

When catfish eggs hatch, the larvae rely on the yolk sac to provide the nutritional needs before they begin feeding. The larvae are vulnerable to starvation and need to feed continuously during this period.

In nature, there isn’t always a constant supply of feed and many fry will die during this first stage of life. Traditionally, in hatcheries, larvae of African catfish have been offered natural food organisms and Artemia was often the
most common choice. However, good Artemia is getting scarce and not always available in sufficient quantities and quality in Africa.

With the arrival of new generation larval diet such Gemma Wean, this has changed. Feeding this high quality starter diet provides all fry with an equal opportunity to feed, ensuring a very high survival rate.

Skretting’s Gemma Wean is a complete substitute for live feeds in hatcheries. When feeding a sophisticated manufactured feed, hatcheries are not only less dependent on live feed, but also exposed to less risk of pathogen transmission via live feed sources.


Jade is highly digestible, palatable and contains hydrolyzed proteins and high quality marine ingredients such as krill meal to boost the feed intake. Jade is formulated with high concentrations of protein, highly unsaturated fatty acids and phospholipids to provide an optimal nutritional profile for shrimp in high density nursery systems.

Jade includes phytobiotics and natural immunostimulants that help shrimp cope with
disease challenges and stress caused by environmental conditions. Probiotics are also added to support the gut health and reduce the impact of bacteria.

Jade is available in three sizes that are carefully processed to achieve a homogeneous particle size distribution and eliminate dust. These high quality crumbles and micro-pellets ensure minimal nutrient loss and stable water quality.


Lorica diets contain a complex profile of innovative functional ingredients designed
to safeguard shrimp during challenging phases in their life cycle, including transfer
and handling.

Lorica supports the primary defences of shrimp from environmental threats. It also
acts to improve the structure of the digestive tract and hepatopancreas, and their ability to resist pathogens.

Improved shielding of a shrimp from pathogenic bacteria not only improves the
viability of that individual but reduces the potential of release of bacteria to infect other shrimp. This concept reduces the epidemic potential of an infection outbreak.

It is recommended to use Lorica in the 2 weeks leading up to expected challenges,
such as transfer and handling, and 2 weeks after the challenge event. Please ask your local Skretting feed specialist for specific recommendations.


When tilapia eggs hatch, the larvae rely on the yolk sac to provide the nutritional needs before they begin feeding. The larvae are vulnerable to starvation and need to feed continuously during this period. In nature, there isn’t always a constant supply of feed and many fry will die during this first stage of life.

In hatcheries however, sufficient amounts of high quality starter feeds can be continuously supplied. Feed production techniques allow us to produce feeds with properties that fit specific life stage needs. The slow sinking Nutra crumbles give all fry an equal opportunity to feed.

Nutra micropellet technology ensures uniform particle sizes that float, for easy capture by fingerlings, ensuring a very high survival rate and uniform growth.

In these specialised feeds, both the digestible protein and digestible energy are adjusted according to fish size. As body size increases, the percentage of digestible protein needed for optimal growth decreases along with it.
