Mean prey size measure eaten by predator progressively growing larger by growing larger predator size measure 3. [All] predator show hobby [at] species prey [at] certain size measure 4. Predator generally take all kinds of prey 5. Preying prey by conducive predator [of] them change exploitation in density of prey. 6. Predator species possible change its food more or less permanently to species in is balance [of] ecology 7. Prey its amount [is] reduced clearly by predator pressure 8. Community prey composition influenced by predator 9. big population of prey can stimulat...

REFRIGERATION [AT] PRODUCT RESULT OF FISHERY. Handling of low temperature 1. cold Depository ( 5 - 15 degree of Celcius ) 2. chilled Depository ( 1 - 5 degree of Celcius ) 3. Chilled Storage ( - 1 - 0 degree of Celcius ) 4. Depository [of] frost ( less than - 2 degree of Celcius ). Principal of refrigeration (it) is interesting [is] hot the than food-stuff till reach wanted temperature without happened change of physical. Usefulness of refrigeration 1. Pursuing reaction of bichemistry and chemistry 2. Pursuing enzyme aktifitas 3. Pursuing microbe aktifitas. Refrigeration media 1. ice cube 2. dry ice 3. RSW ( Refregrated Sea Water) 4. cool air.
