General information

Once again, Ocean Nutrition is leading the innovation path by introducing a revolutionary concept: Instant Baby Brine Shrimp. Baby brine shrimp (nauplii of Artemia salina) are widely used in the aquarium hobby as food during the first stages of many delicate fishes and for invertebrates. To this date, there has been little or no innovation in the use of Baby Brine Shrimp in the hobby. The whole process of hatching brine shrimp cysts at home can be tedious and cumbersome. More often than not, due to variables such as improper storage, the hatching rate can be rather disappointing. The next challenge facing the hobbyist is synchronizing the hatching time with first feeding of the fry. Those days are over. Ocean Nutrition has developed the Instant Baby Brine Shrimp, a revolutionary off the shelf product that allows you to use brine shrimp when and where you need them. The product consists entirely of sterile newborn nauplii in an aqueous solution. The nauplii have a very good buoyancy, as if you are dealing with a live product !! The product can be kept and stored at room temperature. Once open, the product must be kept in the refrigerator. To avoid any quality issues make sure that the security strip is complete at the time of purchase. It contains a net weight of over 20g drain weight, or in excess of 1.5 million nauplii. Ideal for delicate small fish, fish fry and invertebrates. One bottle contains in excess of 1.5 million Artemia nauplii. Developed in collaboration with the Artemia Reference Center (of the Ghent University in Belgium). Does not cloud the water.

Did you know?

Female Artemia can produce up to 57 nauplii per day.

Do fish need to be fed on a daily basis?

Your fish can be fed everyday just make sure there is a lot of variation in their diet. However, as our fish are contained in a relatively small environment and to avoid obesity it is generally accepted that a 1 day a week starve is a good idea. Of course, this theory should not be applied for breeders and tanks full of juvenile fish. Starving juvenile fish will have irreversible effect leading more often to deformed or stunted fish. This is particularly true for discus (small discus with out of proportion eyes).

How much food do I need to give my fish?

Once again, fish are opportunistic feeders. However, it isn’t because the fish rise to the surface of the tank each time one walks buy that one needs to feed them. The importance lies in the quality rather than the quantity. Contrary to popular belief, fish don’t need to eat as much as we think and there are several reasons for this. First and foremost fish unlike us don’t need to spend much energy in fighting gravity as they evolve in a three dimensional environment. Second reason is that fish are cold blooded animals and don’t spend any energy unlike us to keep warm. Third reason is that humans spend lots of energy in producing urine fish just produce ammonia. But last and not least, our fish evolve in an artificial environment however large the tank may well be.

Why should I feed my fish with frozen feeds?

There are several reasons why we recommend to use our frozen feeds. The flash-freezing process avoid crystals forming in the prey so the animal does not get damaged by the freezing process. What you get is the prey in its natural form. One thing is for sure, frozen food is the next best thing compared to live food. The freezing process ensures that most of the goodness in the food is preserved. Our range and packaging offers great versatility and variety.

What are HUFA's?

Highly Unsaturated Fatty Acids (HUFA) are a subcategory of unsaturated fatty acids (FA) which contain 20 or more carbon atoms and multiple double bonds. Common HUFA encountered in fish nutrition are EPA and DHA, both omega-3 fatty acids. EPA and DHA are essential for fish health. These HUFA must either be obtained in the fish’s diet, or made through the conversion of other FA such as Linolenic Acid—although not all fish are capable of this or efficient at the process, making incorporation in the diet important. Studies suggest that fish benefit most from directly consuming the EPA and DHA as evidenced by increased rates of growth and survival. Why don’t you give your fish a HUFA boost by feeding them with our HUFA enriched artemia?

What are the optimal conditions for hatching Ocean Nutrition artemia cysts?

Artemia cysts should be stored in cool dry place prior and after opening the packaging. Standard guidelines are: * Maximum 2 gram of dry cysts per liter, * pH > 8, * Salinity between 25 and 35 gram per liter, * A lot of aeration and light, * Water temperature between 26 and 29 °C (do not exceed 30 °C°). It is important to keep the water properly buffered in order to maintain a high pH. Make sure that all equipment is properly cleaned to increase your chances of success.

My artemia culture failed to hatch. Are there any other alternatives to feeding artemia nauplii?

It has happened to the best of us and you know what the old saying is “never put all your eggs in the same basket”. First of all before setting up your artemia hatchery make sure that all the basics are respected. Is the salinity correct? Is the pH OK? Do I need to buffer my pH? Are my cyst properly stored? These are all variables that can easily be avoided. In general, it is a good idea to start two cultures with a couple of hours delay between each culture. Should one fail, you’ve got a back-up plan. We do have an off the shelf solution which is just as good as the real thing. It’s called the instant baby brine shrimp. This product has brilliant buoyancy properties that will fool any prey. The Instant Baby Brine Shrimp is an ideal extra to any invertebrate tank. Other products such as our frozen Cyclops and red plankton also work successfully.
