若没记错，鲟鱼和鲨鱼一样，是卵胎生的，即卵在体内孵化。

BASS真的很好吃, 尤其清蒸. 俺总是在禁钓期钓到, 只好放生, 而过了禁钓期就很少钓到, 奇哉怪哉. 向你学习如何钓BASS.

太正常了， 要不还叫什么禁钓期？  就是因为那个时间太好钓了。 禁钓期一过，一天不如一天。深有感触。

Its range extends from New Brunswick, Canada to the eastern coast of Florida. It was in great abundance when the first settlers came to America, but has since declined due to overfishing and water pollution. It is considered threatened, endangered and even extinct in much of its original habitats. The fish can reach sixty years of age, fifteen feet in length and over eight hundred pounds in weight.

Physical appearance

Rather than having true scales, the Atlantic sturgeon has five rows of bony plates known as [url="http://en.wikipedia.org/wiki/Scutes]scutes. Specimens weighing over eight hundred pounds and nearly fifteen feet in length have been recorded, but they typically grow to be six to eight feet and no more than three hundred pounds. Its coloration ranges from bluish-black and olive green on its back to white on its underside. It has a longer snout than other sturgeons and has four barbels at the side of its mouth.

Life cycle

Atlantic sturgeon under six years of age stay in the brackish water where they were born before moving into the ocean.

Atlantic sturgeon may take anywhere from seven to twenty-three years to become sexually mature, depending on the sex and temperature of the water. When mature, they travel upstream to [url="http://en.wikipedia.org/wiki/Spawning]spawn. The females may lay 800,000 to 3.75 million eggs in a single year, but do so every two to six years. After laying their eggs, females will travel back downstream, but males may remain upstream after spawning until the water becomes too cold to remain. At that point, they return downstream and may return to the ocean, where they stay near the coastline.

Sturgeon can often live to the age of sixty years old. Accounts of sturgeon over the age of one hundred were not uncommon in colonial times. And also are as large as 3 to 5 feet in young stage.

Economic history

Originally, the Atlantic sturgeon was considered a worthless fish. Its rough skin would often rip nets, keeping fishermen from catching more profitable fish. However, when products derived from the atlantic sturgeon were found, their popularity quickly rose. The [url="http://en.wikipedia.org/wiki/13_colonies]colonies soon found atlantic sturgeon to be a profitable resource, second in profit only to lobsters. Other fisheries along the Atlantic coast harvested them for use as food, a leather material used in clothing and bookbinding, and isinglass, a gelatinous substance used in clarifying jellies, glues, windows, wines and beer. In the late 1800s, seven million pounds of sturgeon meat was exported from the US per year. Within years, however, that amount dropped to 22,000 pounds. The number later rose to about 200,000 pounds a year in the 1950s. Now, sturgeons are primarily used for the production of caviar.

Population status

The U.S. [url="http://en.wikipedia.org/wiki/Fish_and_Wildlife_Service]Fish and Wildlife Service does not list the species as threatened or endangered on a nationwide level, but does acknowledge that it is threatened in Connecticut and Massachusetts. The American Fisheries Society, however, considers the fish as threatened throughout its entire range, although it is believed to no longer inhabit the full range it once did.

The University of Georgia is conducting an ongoing study on the life history of Atlantic sturgeon on the Altamaha river in Georgia.

本夫估计也是小鲟龙，活蹦乱跳的，寄生虫也不可能是那么大，今早一个人说可能是寄生虫，可惜因怕误了小生命所以没来得及查验，就顺手把它放回水里了，，，

今天处理鲟的时候，感觉那肉还真的很嫩而且柔软，至于吃法上次ZHEN渔夫说醋熘鲟鱼不错，，

今天还有个大发现，鲟的内脏和其他鱼类的确很有不同之处，鳃少而硬，肚子厚重而长，似乎有肺部，而且似乎有个很大的心脏，足见其古老，请问专业人士可否知道鲟龙是卵生还是胎生啊？

开禁前用8磅线钓着一条和你这条差不多的STURGEON，但用的是假饵。后来又经常用假饵钓到，只是由于线承重不够，不是断线就是采取不收紧线让其脱钩的策略。个人感觉，用假饵反而比用蚯蚓成功率高的多。不过我也想不通为什么。

原来是卵生。我一直以为它是卵胎生呢，现在才回想起俄国人的昂贵鱼子酱就是鲟鱼卵做的。

原来都出了西岛尖了，昨可把本夫折腾够戗了。。。

另择他日吧

有日子没见你了，在钓吗？

用假耳不太可能钓鲟龙，可能是挂上来的，，

有些蹊跷。。

1，钓BASS上瘾，一天不钓好象没刷牙，，，，，
治疗方法， 急流公园西侧，每日早五点，短竿，小活鱼，小钩。（一定要穿救生衣）
2，鲟鱼上的寄生虫
几次鲟鱼上钩，都发现与小拇指粗细，比中指长一些的鲜活的生物依附在其体上，多在鱼翅下。那是水蛭。不知道鱼夫看到的是否相同之物？
3，以为渔夫怜悯鲟鱼，不食之，只讲了醋熘鱼片。其实，目前我们这里钓上的鲟鱼最佳之食处在其骨与皮还有翅。将鱼肉剔下另用（或鱼片，或鱼松），留下洗净的骨，皮，翅，成就一锅上等海鲜汤。美味敢比一般餐馆的鱼翅燕窝汤。因为它是新鲜的活鱼成汤。
4，许多鱼都可以用假鱼饵钓上，鲟鱼更不例外。看看钓鱼手册，你能看到，在北面很多湖内是禁止使用活饵的。
5，折腾鱼夫，深有愧疚。
他日再赴英武行
抛竿垂钓赏月影
江中执得鲟龙归
佳肴美味共液琼

早上5点半起床，简单吃点东西，老地方，老方法。从6点10分到10点，3小时以后，先收获石鲈1条，再过半小时，天道酬勤啊，得1磅半bass一条，这是今年到目前为止本人钓的最大的一条。之后半小时没收获，放石鲈，拿bass，回家。我think bass season is over. 再钓得到bass，就要看运气，技术和耐心了。运气和耐心在一天里是越用越少，而技术的提高不是一天两天的事，我的技术不怎样，全靠前2个消耗一点少一点的东西。唉，睡觉咯。累了。
