Mix of live benthic Copepods  Tisbe sp.   and live rotifers  Brachionus plicatilis   in bottle.

Grown in the laboratory and fed exclusively with phytoplankton.

Excellent mixture of zooplankton to feed a wide variety of organisms due to the diversity of sizes and stages of each species, in addition to keeping dinoflagellate pests at bay.

General characteristics

These small crustaceans make up more than 70% of the components of zooplankton in all seas and are free-living organisms.
Its size ranges from 0.2-2.5mm.
They are capable of swimming but due to their small size they cannot define their own destiny and are carried away by water currents, which is why they are part of the plankton.
They feed on phytoplankton (microalgae) and serve as food for organisms of higher trophic levels, including among others, fish.
They have benthic habits, which allows them to be kept at high densities
High reproductive potential (high fecundity and short generations)
Their characteristic zigzag movement is an important visual stimulus for many fish
They have sexual reproduction (separate sexes) and go through six larval stages of nauplii and five stages of copepodites before molting into adults.

Advantages of copepods as food

  • Enhances the natural coloring of fish and crustaceans.
  • Strengthens the body's immune system.
  • They are especially useful with some inhabitants of the more delicate aquarium in their diet, either because they are sick or because they do not accept inert food.
  • Copepods in marine fish larval culture have been shown to ensure normal development with improvements in growth and survival, greatly reducing disease, malformation and abnormal pigmentation.
  • As it is benthic and is therefore fixed to the substrate it encounters (rocks, glass, bottom, ...) it facilitates the feeding of slow swimming fish such as Synchiropus.

Advantages of rotifers as food

  • It is ideal as a food due to its small size, slow movement, ability to be suspended in the water column and relative ease of growing at high densities.
  • The size range of this organism is adequate for most cultured fish, 125-260 µm, which is an intermediate size between microalgae (20 µm) and brine shrimp nauplii (500 µm).
  • They have a high reproductive capacity. Under favorable conditions, they reproduce asexually, with the females producing an egg in a matter of hours. They are capable of reproducing at only one day of age (unlike copepods or brine shrimp, which need 2-3 weeks).
  • Another advantage is that they support high densities in the crop.
  • They withstand variable conditions in the environment in which they are found (temperature, pH, salinity, oxygen, ...).
  • They have a slow movement that allows organisms with difficulties to feed on them in a simpler way.
  • By having a non-selective filtration (such as Artemia) they become ideal prey to be enriched as best suits us.
  • They are easily digestible.
  • Seawater is their most optimal medium but they live perfectly in a marine aquarium since they are capable of supporting highly variable salinity ranges (1-97ppm).

When to use copepods and for what

  • They are an excellent food source for somewhat more delicate fish: corals and other invertebrates such as anemones, fish larvae, seahorses, Mandarin fish and Anthias fish.
  • If our purpose is to create more zooplankton in our aquarium, we must add them at night so that they are not eaten immediately after casting them.
  • They are the best option to regain the appetite in fish that are sick or that do not eat, especially mandarins, pipefish, seahorses and fish that do not accept inert food.
  • They feed on aquarium detritus, microalgae, ground food, ...
  • Always add the contents of the bag to the end opposite the water outlet of the tank.

When to use rotifers and for what

  • The rotifer is not the natural food of marine fish larvae. However, since it was used in Japan as the first larval food in 1965, it has become the most widely cultivated live food in intensive aquaculture. For all this, it is widely used for feeding larvae of fish and marine crustaceans today.
  • It is essential as the first live food due to the fact that the Artemia nauplii is inaccessible to the larvae during the first days of life.
  • If our purpose is to create more zooplankton in our aquarium, we must add them at night so that they are not eaten immediately after casting them.
  • Widely used for feeding corals and fish larvae. It should be noted that it is especially recommended for the breeding of fish such as clownfish or seahorses since they have a very small mouth size and rotifers become the ideal prey for the development of these fish.
  • Ideal for feeding all the invertebrates in our aquarium: anemones, sponges, starfish, ...
