FISH CULTURE

CONDUCTING FISH of MANFISH., Morphology and Habit Of Fish of Manfis. Manfish or which [is] recognized also with term ' Fish Angel' coming from territorial water of Amazon, South America. Manfish ( Pterophyllum Scalare ) pertained into set of relatives of Cichlidae, having marking of morfologis the following habit and: " Owning type and colour which vary " Form flimsy body, with body like dart " Stomach fin and its back fin unfold wide up at tail, so that see as bow which [is] transparent dark chromatic " [At] part of its chest there are two fin which [is] length pendant to part of tail " Taking care of and protecting its clan " Have the character of omnivorously " Pertained easy to accept various food type in so many source and form. Some fish type of Manfish recognized and have expanded in Indonesia for example [is]: Diamond ( Berlian ), Imperial, Marble and of Black-White. Diamond ( Berlian ) silver chromatic gleam until dusty green. [At] p...

Mineral function [at] food to fish. Mineral Iihat vitamins required by fish for example calcium ( Ca), phosphorus ( P), and natrium of klor ( in compound of Naci), manganese ( Mn), ferrum ( Fe), copper ( Cu), iodine ( I), and cobalt ( Co). [Is] the same as with vitamin, mineral very required by fish in number which [do] not too big. Calcium ( Ca) and phosphorus ( P) needed to forming of bone / growth and to take care of body network function can work normally. Chloride Natrium ( Nacl) have an effect on in growth, but suggested [by] its usage [do] not too much. Iron ( Fe) required for the forming of red corpuscle, while copper ( Cu) assist in usage of iron by body. Iodine ( [Is] i) needed to making of tiroksin ( hormone of timid) and manganese ( Mn) have an effect on in course of ovulasi/ reproduction. source : Ir. M. Firdaus Sahwan, M.M, 2001

Vitamin. Vitamin needed in number which relative a few/little, especially to keep in good health and growth of fish body. Evaluated from nature of its physical, vitamin can be divided into two faction that is dissolve vitamin in dissolve vitamin and water in fat. dissolve vitamin in water for example tiamin ( vitamin of B), riboflavin ( vitamin of B2), sour [of] pantotenat ( vitamin of B6), biotin, and kobalamin ( vitamin of B 2), and others. dissolve vitamin in fat for example retinol ( vitamin of A), or kolekalsiferol of ergokalsiferol ( vitamin of D), alpha of tokoferol ( vitamin of E), and menadion ', vitamin of K). Vitamin of B1 B6, and functioning B12 to support growth and also can stimulate passion eat, while vitamin of B2 play a part in growth and transfer of food Iihat vitamins ( like carbohydrate, fat, and protein) of cells in fish body and also for the process of reproduction. Vitamin of A functioning to support health of eye, while vitamin of D required for the process ...

Carbohydrate. Carbohydrate represent the source of energi and in general come from flora which [is] forming of [him/ it] [pass/through] photosynthesis process constructively sunshine. In food formulasi, carbohydrate of[is including group which [is] often referred [as] [by] NFE (" nitrogen of free extract) or in Indonesian term of BETN ( extract materials without nitrogen). This BETN contain karbohidrat,gula, extract, and most of classified [by] Iihat vitamins [is] hemiselulosa in food-stuff. Assess BETN obtained from number quantifying of protein, fat, dusty, harsh fibre, and water lessened [by] 100. source : Ir. M. Firdaus Sahwan M.M

Role of Fat to making of food made in. Functioning fat as source of energi and assist absorbtion of certain minerals ( especially calcium) and also vitamin. dissolve vitamin in fat ( vitamin of A, D, E, K). In relation to food made in usefulness of fat have an effect on to feeling and food tekstur which [is] dibuat.oleh in consequence fat also have role in course of metabolism and growth of fish. fat of Esensial required by fish also in the form of sour types [of] unsatiated fat, for example acid of linoleic ( more knowledgeable with acid of lenoleat), sour [of] linolenic ( more knowledgeable with acid of lenolenat), and arachidonic ( more knowledgeable with arakidonat). Fat pertained [is] easy to oxidized so that its use in making of food made in its amount [is] limited. If used fat content too high frequently by maker [party/ side] enhanced with materials of antioksidan to pursue the happening of oxidation process. source : Ir. M. Firdaus Sahwan M.M

Protein. Protein represent top-drawer element in compilation of food formulasi because effort conducting expect growth of fish which quickly. In this case, protein have three function to body that is a) as constructor which forming various new network for growth, to changing damage network, and also reproduction, b) as regulator which play a part in forming of custodian hormone and enzyme and regulator various metabolism process in fish body, c) as burner because carbon element which consist in in it can be functioned as source of energi at the (time) of requirement of energi [do] not fufilled by fat and carbohydrate. Protein molecule lapped over from a number of acid of amino upon which base. Quality of protein very determined by sour composition [of] its compiler amino. This composition will differ [among/between] one materials with other materials. From [about/around] twenty sour type [of] amino exist in nature, ten among others represent acid of amino which [is] esensial which cann...

IMPORTANT MEANING [of] FOOD TO FISH. AVAILIBILITY OF FOOD IN NUMBER which enough is, timely, and valuable [of] good gizi represent one of [the] very important factor in fish conducting business activity. Ready [of] food which disagree with amount of looked after fish cause fish growth rate become tardyly. As a result yielded production disagree with which [is] expected. Basically, source of food to conservancy fish,. coming from natural food and food made in. Because of amount of natural food in pool / territorial water very limited and less adequate ( especially for the activity of fish conducting intensively and also semiintensi) hence [so that/ to be] reached [by] fish growth rate, good require to be given [by] side dish or food made in as according to requirement of fish. If good fish growth rate hence conservancy time become briefer so that pool productivity / territorial water also mount because period produce looked after fish become shorterly. Problems which often become constr...
