NATURAL FOOD FOR THE PRAWN
NATURAL FOOD FOR THE PRAWN.
Natural Food represent indispensablelity need its levying for the food of prawn larva. Although many plankton type able to be used as [by] prawn larva food, but for good natural food [of] hams fulfill some conditions, that is - Having size measure and form matching with prawn larva mouth - its Obstetrical [of] high him - solid Cell content and have flimsy cell wall, so that [is] easy to permeated - Quickly multiply and have tolerance which high enough to change of environmental factor - [Do] not [release] poisonous compound - Movement of it is not overactive, so that [is] easy to arrested by prawn larva.
To take care of the availibility of natural food for the larva of prawn, hence require to be [done/conducted] [by] natural food culture which with quality and optimal amount. Some plankton type which [is] often used for the food of prawn [is] Skeletonema Costatum, Tetraselmis Chilii, Chaetoceros Calcitrans, Brachionus Plicatilis and of Artemia Sp.
TECHNIQUE CULTURE PLANKTON.
Pure Culture.
Way of this [done/conducted] in media [so that/ to be] to get one plankton species. Usually media [so that/ to be] fertilized with manure matching with wanted plankton. required equipments, for example, petridish, tail ose / mikropipet, erienmeyer, pipette, save microscope and reaction. Entire/All culture media and equipments except microscope, before used have to be sterilized in autoclave ( temperature 100°C, pressure 1 Atmosfir during 10 minute).
Condensation [so that/ to be] which have been fertilized, to be infused petridish, let a few moments become solidly. Take example [of] irrigate plankton with needle of ose / mikropipet and dab to surface of media [so that/ to be], [is] later;then closed and kept [at] room;chamber temperature. Few days later;then surface [so that/ to be] the have been growed [by] example [of] plankton colonys. By using microscope, each colony perceived and searched [by] plankton colony desired. If have been got, hence can be developed in tube react and used as [by] seed. If colony perceived still mixed with other type, hence the inokulasi have to repeat get pure colony. Pure colony [of] inkubasi in room which [is] ber-AC to take care of stability of temperature [among/between] 25 - 27°C.
