FISH CULTURE

SeaHorse ( Hippocampus Spp ) Beautiful. SeaHorse recognized [do] not only as entertainer animal [in] aquarium but also as " strong drug", adder of stamina. Even a factory entertain in Indonesia clearly mention sea-horse as one of [the] important materials [at] raw material composition list. Hippocampus come from Greek of hippos meaning and horse of campus meaning sea monster. In state mythology, hippocampus [is] a vehicle of sea deitys. Sea-Horse ( Hippocampus Spp ) have also inspired many people to make artistic object, article, poem, company logo or organizational mascot. Spreading of sea-horse enough wide [of], but because its [his/its] famous in berkamuflase, seahorse oftentimes [do] not seen. Sea-Horse can alter husk pattern and colour accomodate environment and also make a move tardy so that almost [do] not detect " opponent". Some sea-horse species have part of transparent body so that [do] not seen in photo and need more brooding perception to be able to see...

Degree of acidity ( pH) [at] pool of gouramy. Simply, congeniality of pH show the condition of or acid of basa from a[n territorial water. Degree of acidity also represent indicator able to influence the availibility of other elements very required for the growth of fish. Assess low pH [is] indication that territorial water of acid, while high pH [is] indication territorial water of basa. Both [of] this bad condition for the activity of conducting. Change of pH [is] on the spur of the moment marked by swimming fish [it] very quickly. If/When happened degradation of pH continuously, will go out abundant mucus or husk iritasi so that fish will [is] easy to attacked [by] disease. Condition of which good to size measure acidity of territorial water of conducting reside in [at] gyration of pH 6 - 8. Source : R. Eko Prihartono, 2004.

Brightness ( turbidity ) pool of gouramy. Brightness also can be made as a(n) indicator fertility of pool media used to look after fish. Brightness which good to fish conducting business activity [is] 25 - 50 cm. Factor influencing brightness non coming from Mud, but plankton from result of needed to fertilization [is] fish food.

Alkalinitas ( Alk) [at] fishpond. Alkalinitas represent fertility value a[n pool pursuant to to the number of carbonate compound content and bicarbonate ( Caco3) in conservancy media water. Alkalinitas have the character of to neutralize strong acid which yielded by existing other element in water. Despitefully, this compound also function as prop ( buffer) existence of other compound. Content of Caco3 in pool counted 30-200 mg / l indicate that the the pool productive enough. Source R. Eko Prihartono, 2004.

Ammonia ( NH3) [at] pool of gouramy. End result from a[n process of metabolisms protein which [do] not profit [is] ammonia ( NH3). Change of ammonia content in a[n territorial water should not be sudden so that fish can live with. Change of sudden ammonia content will cause damage fish gill network so that fish can die. Crisis fish boundary to dissolve ammonia content in conservancy media [is] 0,6 mg / l. but there [is] still lenient gouramy with storey;level 3,8 mg / l [at] sushu 30 degree of celcius as critical boundary [of] him. Gouramy have tolerance [at] rate 1 mg / l, but dissolve oxygen content have to above 5 mg / l. Source of R. Eko Prihartono, 2004.

Technics [of] processing of fish [done/conducted] by 1. Heat 2. Dehydration 3. Pressure of Osmotic 4. Chemicals Hot. target to kill activity and microbe of enzimatis. Process warm-up [done/conducted] by Poaching. Process poaching, causing the happening of make-up of heat of[is existence of enlargement of enlargement of molecule. One of [the] product processing of poaching result. evaporation. Process evaporation, overcome high hot to [pass/through] aqueous vapours as a mean to kill microbe. Vapour overcome to product, its effect [of] fish flesh will experience of denaturasi ( denaturing of physical, [is] same protein but nature of chemistry change). Poaching and evaporation cause the happening of denaturasi, irrigate in fish body decrease hence microbe grow badly. Protein fastener of dilution become to decrease Pateurisasi. Happened [in] fish canning plant. Exploiting of heat with certain temperature utilize him to kill microbe. Dehydration. Exploiting with a. Sunshine ( dry fish b. d...

Dissolve oxygen ( O 2 ) for gouramy. As does other mortal, fish stand in need of oxygen for breathing in air and also process metabolism having an effect on to growth rate and [his/its] growth. less Oxygen content can cause fish of stres and facilitate disease attack fish. Obstetrical [of] dissolve oxygen equal to 7,8 ppm represent ideal content for the activity of energy kindness of gouramy. source : R. Eko Prihartono, 2004.
