After contest, proposal and reflections part 2 (updated 19.10.2016)

!Updated parts are written in italic!

During each contest I noticed things that didn’t work properly with criteria so I tried to make them more effective and simple without loosing the objectivity of the judgment.

During the Paris International Shrimp Contest there were some modifications made by Yoann Petitjean and myself, some of them worked nicely other need to be adjusted, therefore I will take the old criteria used in European Shrimps Contest and improve them again.

Many asked about the criteria and how they work, well let’s have a closer look starting with the first two categories Red bee and black bee (old category 1-2-3-4).

New criteria proposal:


shrimps judging criteria category 1 red bee

shrimps judging criteria category 1 red bee


shrimps judging criteria category 3 black bee

shrimps judging criteria category 3 black bee

Old criteria:

Old judging criteria category 1 red bee a-s

Explanations of new criteria and motivations:

First row: on the left you have the number of the tank on the right the description of the category making easier for judges to look at the right tank.

Size: if the size of just one shrimp present in the whole tank (yes, judges have to look at all shrimps) is less than 3 cm, the set will lose 10 points as penalty. During some contest we had problem to judge shrimps because they had a size of 1-1.5 cm making difficult to compare with bigger shrimps and we talked about disqualification. As in last two contest I judged I didn’t saw such small shrimps anymore, I would propose a penalty of -10 points for shrimps under 3 cm as reminder and giving 0 point instead 5 for shrimps that have the right size, because this should be the normality. I won’t give more points for shrimps that are bigger than 3 cm because this will have a side effect on a contest, breeder tent to bring bigger shrimps to gain more points despite the quality of the shrimps self. 

Homogeneity: the homogeneity of size have to be judged on the 3/4 chosen shrimps of the set (sets are composed by 4-5 shrimps except unstable crossbreed that are composed by 3-4 shrimps), same sized shrimps gain more point. Homogeneity of color and pattern is also important, the 3/4 shrimps need to have the same colors and the same pattern, this mean that if shrimps are grade S band V they should have all band V and same colors, not two band V and one tiger tooth or two shrimps with good white and red and one with pinkish white and red. This criteria didn’t changed from previous version because seem to work.

Pattern: here we will look the pattern in detail, the pattern should be well distinct, this mean that a shrimp that have a band V need to have it well definite and not one side of the body band V and other side of the body hinomaru. This criteria will also remain the same of the old.

Colors:  as you can see I improved a little bit the points given for colors and now we have a ratio of 60:20:20 (color : pattern : homogeneity) instead 45:20:20:10:5 (color : pattern : homogeneity : health : size) this will hopefully improve with the time the quality of shrimps in competition. Legs and tail coloration now are 20 points worth, good quality shrimps should have fully colored legs and tail; if legs are red or white or half red and half white is not important because this is just a distinctive feature of breeders shrimps lines, the important thing is that are full colored.  White color density is also very important, bee should have a thick dense white color without transparency. White and red colors purity, mean that white color have to be pure white and not pink and red have to be pure red not orange; often we can see shrimps that have a dense white but unfortunately white is dirty, have a bit or pink tonality.

Health: shrimps that have deformations, diseases, missing limbs or any kind of abnormality should not take part of a contest and be immediately disqualified, this is a common opinion, we saw this rule applied for the first time in Paris and 9 set were disqualified, it was a try and seems to be quite effective, therefore will be applied on new criteria, hoping to discourage the presence of deformed shrimps in future contest. This will be at the first place.

Bottom row: is just the place where the final score will be written

Last but not least  I split the points in more columns so that judges don’t have the need to write points in-between, making easier to read what is written and have less chance to have shrimps set in same category with same final score.

If you have a proposal don’t be afraid, just tell me, I’m only happy to hear other opinions.
