Oreochromis sp CHARACTERISTIC

CHARACTERISTIC of NILA RED.

the NATURE OF BIOLOGY. Still become research materials [all] expert to find red nila genetik. Anticipated that red nila represent result of cross [among/between] fishs which included in family ( Familia) Cichlidae of clan of rose colored Oreochromis mosambicus honorum species which come from Singapore with Oreochromis niloticus, normal chromatic come from Japan. Evaluated from indicator of meristic and of morphometric, red nila represent natural hybrida.

In biological classification, red nila ( Oreochromis sp.) including Perchomorphi ordo, Familia Cichlidae and gender of Oreochromis. Its Characteristics [among/between], other there are colour lines up at vertical [at] tail and body and also back fin and anus fin. Its whitish or yellowish or redish colour ( albino). Its body [of] length and is slim. Scales in form of harsh and king sized stenoid. broken [by] Side Gurat [in] middle shares [of] body. Amount of scale [at] side line 34. Back fin and stomach fin have keen hard and weak radius like thorn.

Red Nila [of] adult [at] age 5 - 6 months can reach body weight 400 - 600 gram per tail. fish of Nila red [of] male and female can be differentiated pursuant to difference of[is nature of genitals of sekunder ( sex-sekunder) and or [pass/through] surgery of network ( sexiologi). Difference of this genitals type [is] formed [by] after seed old age 28 day. Red Nila [of] male have big sisik and after its genitals appliance adult form gibbosity rather sharp-pointed. While female red nila have genital hole at elbow hole of anus. Sisik below/under stomach and chin [at] red nila [of] rose colored male - keen ( red - dark), while [at] rose colored female red nila - pale.

Nose form and mouth of nila red [of] wide male, whereas female red nila rather sharp-pointed. Back fin and fin go with the tide [at] red nila [of] male represent line by snatches, while female red nila [do] not be broken and is [circle;coil]. Nature of this loo like once with fish of nila in general. Like [at] fish faction of Oreochromis in general, red nila measure up to typically in taking care of its clan, that is female mains brood on egg and protect its larva in mouth cavity. Eggs which [is] fruit will hatch in cavity trap and will [release] of after assumed can live on like its mains.


Almost 70 [gratuity/ %] of clan of red nila have male sex. However colour degraded by its mains [do] not be [is] same always. Among others there [is] which [is] redish chromatic, yellowish and albino, sometimes also black or black pock [is] at all. Appearance of red nila see wildly, especially at the (time) of brooding on larva or egg in its mouth. Even oftentimes mainss like this like to attack if/when bothered. However, red nila [is] including tamest fish. If accustomed since childhood ( seed), red nila will encircle whosoever trying coming near [him/ it]. In a state of that way, we earn to give food [at] red nila by hand.


Its wide mouth, its jagged lip, and its uppermost and big eye add appearance of red nila see uniquely, especially if/when holded. Hard thorns [at] back fin and its stomach fin will be flung out to protect its body. In a state of is factious, red nila sometimes dart by unfolding thorns [at] its fin. This matter oftentimes make busy in transportation of red nila. red Nila Sisik very coherent and [do] not easy to release. Situation of its solid body physical. Compared to [of] fish of nila other, flesh of nila thicker red so that fattest looked to be. This matter [of] possibility there [is] its [relation/link] with physical resilience of nila high red enough to change from outside.
