백인종 송어, 황인종 송어? 송어의 종류는?

[킴벌리]

밴에서 우리가 먹은게 송어냐, 숭어는 아니냐 등 의견이 분분했던게 생각나서 리서취 좀 했어요.

어떤분은 송어는 민물생선, 숭어는 바다생선이니 우리가 먹은건 민물생선이니 송어가 틀림없다고도 하셨네요.

그런데 제가 한국에서 산행후 맛본 송어는 연어와 비슷한 색인 오렌지색였던게 분명한데 우리가 어제 먹은건 또 그게 아니라 의견이 분분했던듯 합니다. 

그래서 구글로 리서취 들어가니 5분만에 답이 나왔습니다.  여러종류가 있는데 그 중에 4종류가 가장 많이 눈에 띈다는군요.

카톡에 올린 양파님의 사진을 보면 첫번째로도 보이고 세번째로도 보입니다 ㅎ  양식장에 물어보면 됐을것을 이리 발품을 파는군요 ㅋ

색이 와잇이든 오레지든 맛은 상관이 없대요.  워터 퀄러티하고도 상관이 없답니다.  송어 자체가 워낙 1급수에 사는 어류이기때문이지요.  근육티슈에 카로틴을 저장하는 유전자가 있으면 오렌지색을 띤다고 합니다.  카로틴은 많은 분들이 아시다시피 당근에 있는 색소화합물로서 비타민 A의 전구체 역할을 하지요.  이왕 여기까지 온김에 영양분석까지 한다면,  양질의  단백질이 엄청 함유되어있고 지방도 많지만 거의 오메가 3, 심장을 건강하게 하는데 일조를 하는 불포화 지방산입니다.  그렇다고 콜레스테롤이 아주 없지는 않아요.  우리의 몸은 적당한 콜레스테롤도 필요하르로 염려할 양은 아닙니다.  괄목할 만한 중요한 영양소 중 하나, 비타민 B12, 코발아민 이라고도 하는 영양소가 송어 90-100그램에 일일권장량이 다 들어있답니다. 

코발아민은 부족시 옆산도 부족하기 쉬워서 DNA 합성에 문제가 생깁니다.  뿐만아니라 악성빈혈을 일으킨다고 합니다.

코발아민은 주로 육류, 어류, 특히 소고기 양고기에 다량 함유되어 있는데 소고기를 몇년 안먹었더니 증상이 좀 있었는데 어제는 송어를 포식했습니다.

그러니 오늘밤엔 스카이님께 더더욱 고맙습니다. ㅎ

Trout Species List

Cutthroat Trout
(Onchorhynchus clarki)
The Idaho State Fish

Description
Cutthroat trout are named for the bright red-orange streak in the fold under the jaw. Cutthroat are native to mountain streams, lakes and rivers throughout Idaho. This is the primary reason for its designation as Idaho’s state fish. They are great indicators of water quality, since they prefer very clean, pristine waters. They have been introduced into many of the high mountain lakes. Cutthroat prefer colder water than do the closely related rainbow trout.

Life History
Spawning takes place in the late spring in small tributary streams. The female digs a redd in the gravel with her tail. Cutthroat may spawn more than once and with different partners. Both the male and female are aggressive if other fish try to spawn too close to their redd. Once spawning has been completed, the female will use her body and tail to displace gravel upstream of her redd to cover it. They may spawn during the day or night. The eggs will hatch in about five weeks, early in the summer. The small cutthroat trout may live in the stream where they were born, migrate to another stream, or migrate to a lake. In many Idaho rivers, cutthroat will migrate in the fall, over-winter, and move back to their summer home. You may find yourself angling for cutthroat during only one season in order to find cutthroat large enough to catch. Like the rainbow, their size and age of sexual maturity varies. Cutthroat are usually three years old when they spawn for the first time.

Feeding Habits
Cutthroat trout will feed on aquatic and terrestrial insects. They feed along the surface, but may take insects at any level in the water. Larger cutthroat may feed on smaller fish when available.

Brown Trout
(Salmo trutta)

Description
Brown trout are golden brown in color with large black spots, red spots with pale halos. They are the only trout with both red and black spotting. Young browns have an orange adipose fin.

Brown trout are native to Europe. They were introduced into Idaho waters in 1892. It was not until 1948 that introductions were successful. The brown trout is more tolerant of silt and warm water than native trout and, therefore, has been stocked in areas disturbed by man.

They may be found in rivers, streams, lakes, and reservoirs in the southern part of the state, particularly in the Henry’s Fork River Basin. There are small populations in the Clark Fork River, Lake Pend Oreille, and other waters in the north.

Life History
Spawning occurs in October and early November. With her tail, the female digs a shallow depression in which eggs are deposited. After spawning, she covers the eggs with gravel. The eggs hatch the following April. The juvenile brown trout grow quickly for the first three years. As they reach maturity, growth slows. An adult brown might be 4 to 15 years old.

Feeding Habits
The brown trout is aggressive and territorial, chasing other species away from good cover. It feeds on many different varieties of invertebrates and small fish, both on the bottom and on the surface. Browns forage freely on the surface when mayflies, caddis flies and stone flies are emerging. They will also eat other fish.

Rainbow Trout
(Oncorhynchus mykiss)

Rainbow spawn in streams from mid-April to late June. They use areas of gravel, or cobble, depending on the size of the fish. The female rainbow selects a place in a riffle area below a pool to dig a redd (nest). The female displaces the gravel with her body and tail, and the male fertilizes the eggs as they are deposited. The female covers the eggs with gravel by continuing upstream and the current carries the gravel over the eggs.

The eggs hatch in early to midsummer. The young fish may live in the stream a few months, several years, or their entire life. The growth of those that remain in the stream varies with the amount of food and temperature of stream.

When they mature and are ready to spawn, the rainbow migrate back to the place they were born. The age of sexual maturity depends on the type of rainbow and where it lives. Most rainbow require 3 to 5 years to mature.

Brook Trout
(Salvelinus fontinalis)

Description
The brook trout is one of the most colorful of the trout species. The brook trout is actually a char, characterized by light spots on a dark background. The back is dark green with pale wavy lines; some people these as worm-like markings. The sides are a purple sheen with blue-haloed red spots. There are no black spots on this fish. The pelvic, pectoral and anal fins have white leading edges. Originally native to the eastern U.S. and Canada, the brook trout was introduced into Idaho waters in the early 1900’s. They are now found in many of our streams and lakes.

Life History
The brook trout spawns in October and the eggs hatch in the spring. They can first spawn when they are 18 months old and only three inches long. This feature causes many brook trout populations to overcrowd their habitat resulting in individuals becoming stunted in size.

Feeding Habits
The diet of the brook trout is extremely variable as it includes invertebrates, insects, and fish. Because of this varied diet, many different fishing techniques can take brook trout.

Angling Techniques
Small spinners or spoons are often quite effective, as are both wet and dry flies. Worms also work quite well. To catch brook trout, the lure should be placed close to cover, such as submerged logs or undercut banks. Once the fish has been hooked, it is important to get it into open water as brook trout are notorious for tangling the angler’s line around logs and rocks.

There are many other fish species in Idaho, but the ones above will really get your attention.
