    great help great video and all your videos are just fabulous. I request you to do a video on the detailed explanation of the wet mount technique and how to do it under the micropscope pinpointing each and every detailed point. i watch your vids again and again to be sure i dont miss out anything

    Great Video, I'm already suscribed. Thanks for explain it, it was very clearly. However, I have a question about the Pl/gr, What happen if at a determinated age it has a less animals than suggested?; I must emphasize that at the market it has become normal, for example at PL8 has a 450 PL/gr even less.

    Gracias, genial vídeo, saludos desde EC, ? Como evaluar la calidad genética de postlarvas ?, gracias

      in a farm setting, only by stocking two different genetic strains in a large number of ponds around the same time, which is logistically complicated. Or in an R&D facility.

    thanks for video' i have question for determination the Total vibrio count in shrimp post larvae shall we use sample whole bodies or remove carapace then rinse with sterile sea water

    • @joseantoniosantosdom
      @joseantoniosantosdom 2 роки тому

      Hi, you can do total vibrio count using TCBS agar of water (CFU/mL), not the animal (it doesn't make sense).

    Thank you for the information. How do you determine the # of size classes in a biometry?

    • @hashtagfish8542
      @hashtagfish8542  3 роки тому

      Hi Enrique, for that you would need to weigh 30-50 shrimp individually (instead of counting how many pieces in 1kg for instance), then calculating the % in each class. The size classes you are referring about I suppose to be the ones used by processing plants (number of shrimp per pound, e.g. classes 41/50, 51/60, 61/70, etc.)

    Hi miss , excuse me may i ask you ? Do you ever hear SALT MIX ? I want to make brackish water for culture larva macrobrachium rosenbergii..can i make the brackish water use SALT MIX ? can the larva grow at the brackish water use salt mix ?

    What will happen if we stock 10k pl in 10m2 pond with pl size variation more than 4

    • @hashtagfish8542
      @hashtagfish8542  Рік тому

      First That's is 1000 PL per m2, it is okay for 2 3 week's but then the carrying capacity will be compromised. This density is not commercially viable for the entire grow out period, just for pre nursery, maybe PL 40. Size disparity at start means likely you end up with shrimp of all sizes at the end.

    How many days can shrimp be consider under PL (Post Larvae) stage before it will be called as juvenile?

    Where do you buy the Vannamei PLs?

    • @hashtagfish8542
      @hashtagfish8542  3 роки тому

      Hi Poi San Mok. Currently Giana and I are not directly involved in production (we are now full time researchers), so we don't buy PLs. It depend on the country you are in, of course, but above all you want to visit the hatchery yourself, see if they are biosecure and do routine testing for SPF (if you have closed systems), and do a PL quality check like what Giana explained in the PL Quality video, to see if their PLs are of good quality.
