Nahhh..MPOB isn't the sharpest knife in the kitchen. They are genetically modded to increase yield, lower cost, resistance to pest, etc. The problem with these plantations, they don't talk to each other and they don't tell MPOB everything. Too many trade confidentiality. MPOB, 3-MCPD pun tak pandai nak buat efficiently. Dioxin pun belum tahap expert lagi. When we validate their NGS, at least 40% short read errors, like we have to redo, and not cheap wei.
Much uneaten feed, waste, etc laden with peroxide, antibiotics, copper etc end up there la, bro. While you may not actively supply, they still end up at the same place. We find a/b in farmed salmon too. Fish are full of zoonotic pathogens. Also some antibiotic is use as growth promoters. You may not use it, others may. The fertiliser and pesticide you mentioned, also gets back into the water system and might end up at the fish farm.
Back to Hg....a total Hg analysis isn't going to cut it now that we know MeHg is toxic....to us when we ingest some over a period of time.
no choice, in this industry what they say we have to follow. if they say dont have, then dont have. we aren't gonna be the ones arguing with the board, otherwise we jeopardize our business.
your zoo plankton only applicable to very few types of marine species. siakap , jenahak and those ikan merah tahan lasak types. kerapu, tongkol and others cannot. only use pure cultivated rotifer and artemia. even copipot also we leave out. i know someone who owns a mahi-mahi farm here in malaysia. doing pretty well, and he is only purely on 0.03 micron artemia.
you are partially right but still uninformed. the trend is already moving away from conventional farming of grow-out in sangkar. those are the ones baru nak masuk join in the crowd or yang takde modal. every medium sized player has already moved to partial RAS. low discharge, sludge kek, low maintanence, high efficiency. works well especially for those located at perairan selat melaka. those who export gotta comply with LKIM and their respective jabatan perikanan (moa). since i'm qualified, i was put to certify a few plants and premises and all i see are RAS and CRAS systems. no foreign objects, no foreign modules, no foreign particles, no foreign matter.
the only reason why there was a discussion between us and MPOB is the worries of the discharge flow, industrial waste and the pesticide/ferti that seeps into the soil and slushed away by rainfall into the sea. palm oil plantation and aquafarming dont really work hand in hand. we're more like i hate u, u hate me kind of thing.
but do rest assure, majority are moving or have moved to RAS. its the only way to obtain a higher yield and control diseases and water quality. the protein skimmer, degasser, inducer, ozone and biomedia + UV is enough. conductivity is monitored constantly so i can assure u, there are little or next to no elements of metal. its pretty much a stripped up clean water pretty close to De-ionised water system (cept we retain salinity)
