In fact, I'm looking for a way to maintain a good survival an growth of these shrimps, especially at early life stages (I've heard about some ion deficiencies in marine sea salt which lead to a higher mortality of larvae or juveniles).
Have you any advices concerning the salt quality?
Thanks in advance!
Dear Mr. Rollin,
You can either opt to prepare artificial seawater in bulk by following the formulation which includes NaCl, Na2SO4, KCl, NaHCO3, KBr, H3BO3 and NaF as ingredients or you can purchase commercial sea salts like Tropic Marin Salt Mix, Instant Ocean Salt Mix, Brightwell, Red Sea Coral Pro, Tropic Marin Pro Reef, Reef Crystals Salt, Kent Marine and Seachem Reef Salt etc produced by various companies. The latte are used quite extensively in marine reef tanks and brackish water aquaria to rear and harvest invertebrates and vertebrates alike; while the former is more exclusively used in laboratories where the concentration of the compositions matter more seriously to interpret the outcomes of the culture and experiments alike. The final choice in upon you.
I hope that I was of help to you in any capacities.
Thanking you,
Dr,. Abhishek Mukherjee
Dear Mr. Mukherjee,
Thank you for your advices!
According to your knowledge, is there an optimal commercial among these proposed? (the only comparative results that I have seen were in Atkinson et al. 1997)
Thanking you,
Very interesting question. I have tried the rearing of P. serratus several times with natural water changes. However, the use of artificial water could enhance culture results. I will follow your results! Good luck!

Dear Mr. Rollin,
To answer your question by singling out some of the products among others can be interpret as a publicity campaign on my part and I strongly detest that to happen on an educational platform. But to satisfy your query, I have more than successfully used products by Seachem and can attest to the quality of their products.
Thanking you,
Dr. Abhishek Mukherjee
If you are considering artificial salts, you are also using recycled aquaculture systems (RAS) so my response includes that assumption.
For maturation, spawning and larval rearing high-quality synthetic salt mixes are required that include all trace element and very high-performance RAS. Any water change to prevent the buildup of organics and Nitrate can be added to the growout stage waters.
After PL 10 or so, they become more water quality tolerant and that allows cheaper synthetics that just pay attention to Na/K, Ca/Mg, borates, and TDS, alkalinity etc. while depending upon feed for the input of a lot of the trace elements like Cu, Zn, Fe, Mn, F etc. Denitrification is required to minimize the salt cost.
