FISH CULTURE

ENGINEERING REPAIR OF QUALITY MEDIA CONDUCTING FISH. Pros and cons [is] quality of fishery media very is determining [of] storey;level produce fish. Because fish production will mount if its conservancy media [of] production and goodness will be downhill if its bad conservancy media. Quality of fishery media like water and land;ground will support product increase of fishery if [done/conducted] [by] repair of conducting media quality. Quality of ugly fishery usually happened [at] effort intensive pattern conducting. Generally intensive conducting use solid [is] high dispersion which followed [by] abundant food to cause heaping of fish dirt and pigswill in fish conducting media. This condition result downhill water quality and quality, storey;level acidity of water will mount, oxygen rate go down, and heaping of poison gas. If materials of organic which must be elaborated [by] its amount more than amount of decomposition mikroorganisme, will cause decomposition process become to be purs...

Role of fat in processing of fish 1. As Source of aroma 2. Goal feel 3. Colour 4. Emulsion.

Fat Have content : obstetrical [of] fat 1. Vitamin. dissolve vitamin in fat [is] : Vitamin : A, D, E , K 2. Pigment 3. Cholesterol - LDL - HDL 4. Aroma / Goal feel

Fat [at] fish many [at] shares 1. Red flesh 2. Liver ( Shark ) 3. Head 4. Peritoneum Variation [of] Fat influenced - Migration : transfer activity - Spawning : breeding activity - Feeding : activity eat pursuant to blubber content can be grouped to become 1. Thinly fat 2. medium fat 5 - 15 % 3. Big fat > 15%

Type Damage of Protein 1. Autolisis. dead fish [of] enzyme of fish body will change the the fish hence fish flesh become to soften 2. Denaturasi. Changing of it nature of physical of protein. [At] fresh fish flesh initialy hence becoming is stiff. denaturasi resulted from - Heat - Cool - Chemical Iihat vitamin, salt 3. Koagulasi. furthermore process of denaturasi 4. Change. Protein altered by microbe become acid of amino hence will happened reek [at] fish 5. Condensation.

factors of Genetic. When happened forge of spermatozoa with core of egg, happened also association of material coming from two source. Whether egg and or spermatozoa bring the nature of from each mains that is chromosome. Chromosome represent small object, located in core of cell, accountable for evacuation or transmission of[is nature of clan. This chromosome can only seen when happened bisection of cell by mitosis especially at the (time) of metaphase by special coloration. Size measure and that chromosome form differ in different fish species. But that chromosome can be differentiated to become 4 kinds of as follows ( Draw 16 ): a = Acro(Telo)Centric ( t). chromosome of Telocentric its its[his] that is place area patch yarn when located mitosis near by one of [the] tip of chromosome. b = Subtelocentric ( st). chromosome of Subtelocentric its [of] nearby him to tip of chromosome, but there are short chromosome arm. c = Submetacentric ( sm). chromosome of Submetacentric its its[his] l...

Fish science a lot of that is : Physical, Chemical, Biology. Factor influencing fish chemical composition 1. Intra and species inter 2. Way of living or way of eating 3. different Ground Fishing 4. Time or arrest season 5. Livelines of fish 6. Gender.
