Certified Organic by NASAA

The Difference with our Fish to other growth promoters is that it is

  • Naturally broken down
  • It is 100% pure fish – fish hydrolysate

Hydrofish is the purest fish product available. It is full of organic nutrients that not only feed plants directly but stimulate the millions of microorganisms that provide all the benefits in a healthy soil system.

Perfect for

Promoting plant vigor in vegetables, fruit trees, flower beds, lawns, and natives

What is it? What does it do? How does it work?

  • Derived from Tuna Fish bi-product from a sustainable catch
  • It drives plant growth
  • It is packed full of natural proteins and oils which is the direct food source of bacteria and fungi necessary for plant growth

The way the proteins and oils actually work has only recently been worked out. They are natural chelating agents that make nutrients immediately available to plants and also stimulate soil microbes. It has also been found that fish hydrolysate is better and more effective than fish emulsions due to its natural enzyme digestion process, allowing the natural oils and proteins to stay present.


  • It increases crop yield
  • increases plant vigour
  • Improves nutrient uptake
  • River & groundwater safe
  • Agriculture grade

How To Use Hydrofish

Use Hydrofish on a fortnightly basis. Every other week apply No Frills Fertilisers Seaweed Tonic & Potassium Humate once per month to provide added soil and plant health benefits. An important point to note here is that the area that one persons watering can covers will differ to another persons. Our application rates are based on one watering can covering  about 8-10 m2. The soil condition and stage of plant growth will also govern how much to use, but the key to using these organic concentrates is to ensure that:

  1. the plant leaves are covered to a point of runoff
  2. the soil area around the base of the plant has been showered
  3. always hose residue off well to prevent burning

Note: 1 level cap = 20ml. 1 standard watering can = 9 litres.

Soil Drench:

This is the most common way to use the product. Simply dilute into a watering can and apply to the plant leaves and soil surface.

Foliar Spray:

Some people like to use handheld or backpack sprayers to apply their products. It is a very efficient way of feeding plants. A fine mist needs to be created so that leaf surfaces are covered. Simply dilute into a sprayer with water and cover leaf surfaces until runoff.

Application rates

One rate for all Soil Drench Foliar Spray
1st application 180ml/9lt 10ml/1lt
2nd application 120ml/9lt 10ml/1lt
3rd application 90ml/9lt 10ml/1lt
Maintenance 45-60ml/9lt 10ml/1lt
Natives 45-60ml/9lt 5/–10ml/1lt

Note: when the need for stimulating growth is great(at bud burst, first flower and growth stages) apply the 1st or 2nd rates of 120-180ml per 9lt .

IMPORTANT: Shake well prior to use and don’t store in premixed form. Do not apply to plant leaves during the heat of the day when temperatures are above 28 degrees. Morning and evening are the best times to apply.
