FISH CULTURE

Kinds of spawn. Research to fish larva and egg [in] free nature in Indonesia not yet [done/conducted] many, again, [do] not as in some neighbouring state. Delsman ( 1921 - 1938) representing first person [doing/conducting] research exhaustively to fish larva and egg of pelagis [in] Java Sea. But still limited to some just species that is some of important economic fishs which there are [in] Java Sea. Still many other species [of] bream goodness and also sea fish in Indonesia which not yet been checked. Egg and fish larva which [is] conducting have checked many by [all] student but generally not yet been publicized. Some kinds of egg of pelagis larva and [in] Java Sea got by Delsman like [at] Picture 13. Picture 13. Kinds of spawn of pelagis of Java Sea and Malacca Strait ( Delsman, 1929) Picture boldness 1. Chirocentrus Dorab 2. Unknown 3. Clupea Fimbriata 4. Stelophorus Heterolobus 5. Engraulis Kammalensis 6. Stolephorus Indicus 7. Trichiurus Sp 8. Muraena Sp 9. Decapterus ( Ca...

EARLY CYCLING LIFE FISH. Attention to processs which there are in growth early fish life represent piquancy because relating to the fish population stability in a[n territorial water. Mortalitas in the early growth of fish life generally very big where fluctuation of mortalitas have big share in determining variation [of] produce [at] annually. However this matter still need digs of furthermore research to be developed [by] its benefit. More to fishs species of tropik, a lot of which not yet been laid open. Spawn with its sharess. Vertebrate egg, pursuant to to amount of deutoplasma ( egg yolk, etcetera) which there are in cytoplasma, can be divided [by] two ( Nelsen, 1953 a. egg of Homolecithal ( isolecithal). this Egg faction only there are [at] mammalia. Amount of scanty deutoplasma especially in the form of fat items and biggest egg yolk in cytoplasma. b. egg of Telolecithal. In egg of this faction there are a number of egg yolk gathering [at] one of [the] its pole. fish of Ganoid ...

Fish of Pelagophils. Prolific [in] open or free territorial water where egg result of breeder of [it] will float, go down downwards or climb of surface. [The] mentioned base on to specific gravity spawn determined by oil item content in egg and habit of place marry. Sea fishs a lot is the including into this fish faction. After marrying this fishs take no account of its clan will and all egg left [by] [in] area pembiakan [it]. Even though that fish have [done/conducted] the effort where behaviour when breeder of [it] aim to [so that/ to be] all the [releasing] egg earn fruit. fishs of phytophils, lithophils, and psamophils of pelagophils which have been told above [is] fish which [do] not take care of its clan or take no account of its childs. But there [is] also fish of ovipar paying attention its clan [of] goodness by making den before [doing/conducting] marriage, and there [is] also paying attention its clan after happened marriage, that is with menyimpan or protect its clan [at] ce...

Lobster Freshwater. Differ from prawn pole, lobster can be marketed [by] goodness as prawn consume and also as aquarium decoration. That is why prospect of lobster much more [is] open compared to other prawn commodity. This Lobster in a short time become primadona because amendable [in] basin bargain. Recognition of Type. Lobster [is] generally arrested from coast. Coastal fisherman Baron [is], Yogyakarta with dinghy swim and catch lobster among rocks, [is] later;then sold [by] [in] coast or sent to buyer. Nowadays, freshwater lobster can be developed [by] [in] lawn pool, [is] same as other bream commodity. Freshwater Lobster ( Cherax Sp .) [is] one of [the] pertained gender [is] crustacea ( prawn nation ) which entire/all cycling its life happened [in] freshwater. its big Body size measure naturally. Its body consist of two shares, that is head ( body and cephalotorax) ( abdomen). There [is] part of [among/between] him that is subcephalotorax. Entire/All its body [is] blanketed with c...

Fish and Habitat breeding. Pursuant to to kinds of used [by] habitat [is] fish when breeding, we earn to classify the the fish become some faction like following: Fish of Phytophils [is] prolific fish faction [it] [at] territorial water which there are vegetasi to paste up [released] egg. such territorial water usually stagnan or [his/its] small stream. In fact the condition of such territorial water if seen from dissolve oxygen facet, hence its situation all kinds of that is strarting from territorial water which [is] oxygen insuffiency will be mentioned so that which [is] its rate. enough. However plant exist in in the territorial water presumably represent a[n needed to condition taking place breeder [him/ it]. Fish which including into fish faction of phytophils for example Esox Lucius, Perca Sp., Notemigonus Crysoleucas, some fish which including into Set of relatives of Labridae and of Cyprinidae. In Indonesia which have famous as conducting fish and including into fish of phytop...

fish of Nilem carp [is] usually cooked [by] pepes because its size measure [do] not too big. This fish can be sold in economic package. A. Recognition of Type. Form Body fish of Nilem carp ( Osteochilus Hasselti ) almost similar to goldfish. The difference, fish head of Nilem smaller carp relative. [At] its mouth angle;corners, there are two feeler;complaint tide of peraba. its Body colour [of] grey green. Back fin have 3 hard radius and 12-18 soft radius. Fin go with the tide in form of branch and is symmetrical. Anus fin contributed by 3 hard radius and 5 soft radius. Stomach fin contributed by 1 hard radius and 8 soft radius. Chest fin consist of 1 hard radius and 13-15 soft radius. Amount of sisik [at] side line there [is] 33-36 keping. Near by angle;corner trap to the there [is] 2 sensuous feeler;complaint tide. fish of Nilem carp. can reach body length 32 cm. [In] West Java, fish of nilem have popularitas a little below goldfish. [In] various other area, this fish [is] known as ...

Fish species of ovovivipar its amount much more many from [at] fish of vivipar. [At] fish of ovovivipar, growth of child in mains content get food of supply of available egg yolk and [at] this faction [of] its situation [is] non plasental. But [at] faction of Elasmobranchia which [is] vivipar according to Hoar ( 1969) there are also which [is] its situation [is] non plasental apart from ordinary have placenta. Matter that way [at] fish faction of Elasmobranchia represent complete example [of] [of] food contribution of mains to its clan start from situation which [there] no [gift/ giving] of food of mains until to its for which [is] komplek. Egg [at] fish of ovovivipar pregnant [of] organic material 20 - 40% too many for one borne fish children. Probably because this matter [of] mains only giving just protection to growth of mentioned egg. But there [is] also fish of ovovivipar having egg where organic material content [of] him a few/little. For its mentioned growth [of] fry get need of...
