HOW TO EXTRACT AND COLLECT HOMEMADE FISH EMULSION

     To extract the fish emulsion, you need to separate the liquid part from the solids in the mixture. The solids include sawdust and the still undecomposed parts of the fish like scales, bones, tail, fins and head. The procedure outlined below is labor intensive and will take you 1 hour to extract the fish emulsion and collect it in the plastic bottles.

For safety purposes, wear rubber gloves. Choose gloves that are long and have a thicker lining. You will be handling partially decomposed or undecomposed fish parts and bones that may be sharp and pointed. Wear other safety apparel as needed.

Procedures

Pre-Extraction of the Fish Emulsion

1. Position the basin near the 5-gallon bucket containing the fish emulsion mixture as shown below.

2.  To pre-extract, remove as much of the solids as possible in the mixture.


3.  With your hand, scoop up a mush from the bucket. 
     Wear rubber gloves as you do this.


4.  Squeeze the mush in your hand and let the liquid drip or  trickle down inside the bucket. 

  

 Shown below is the pulp that is left after squeezing the mush.



5.  Put the pulp (squeezed out mush) into the basin.


6. Continue the previous 3 steps until you are left with a slurry inside the bucket that is almost all liquid. Notice the pulp has been piled in the basin at the right and the level of the mixture inside the bucket has gone down.

  

Extracting and Collecting Fish Emulsion in Bottles

1.  For the extraction part, prepare the filter by positioning a funnel in one of the bottles and then lining the window screen piece inside the funnel.


2.  Using a dipper or ladle, scoop up a little of the slurry and pour into the filter as shown  below.

3.  Let the liquid part of the slurry drip down into the funnel and inside the bottle.


4.  When no more liquid is dripping, lift the window screen containing the slurry, by the edges, with the left hand.


5.  Still holding the window screen with the left hand, squeeze the slurry with the right   hand as shown below.

The squeezing is akin to wringing out water from a face towel. Let the squeezed out liquid drip into the funnel and inside the bottle.


6.  As in the pre-extraction process, put the pulp in the basin.


7.  Fill as much plastic bottles as you can with extracted fish emulsion liquid.


Cleaning and Labeling the Fish Emulsion Bottles

1.  Ensure the now-filled up bottles are tightly capped.


2.  With a pair of scissors, cut the old labels of the bottles and remove the old labels.


3.  Clean the outside of the bottles by washing them with soap and water.


4.  With a rag, wipe them dry.


5.  With the new labels, masking tapes and scissors, relabel the bottles of fish emulsion concentrate accordingly.
