What Invasive Species Should You Target?
(Click to expand)
Introduced into the Chesapeake in the early 2000s, Northern Snakehead (Channa argus) like shallow, warm water with vegetation and submerged trees for cover. They boast a mottled pattern that looks similar to a python, and have a round head and large, prominent teeth. Much has been made of the fish’s introduction and status as an invasive species. Many scientists agree that more research will be necessary to determine any negative environmental impacts of the snakehead species introduced into the United States. Regardless, these transplants from Asia have spread throughout the Chesapeake Bay watershed with their populations continuing to increase. They are big, aggressive, strong, and delicious, making them a prime species for sport fishing.
Blue Catfish are long and often slender with a deeply forked tail. A distinguishing feature of the blue catfish is that the anal fin margin, or edge, is straight as if it has been clipped with scissors. All other catfish species have rounded anal fins.
Blue catfish are typically a bluish, gray color on top with a silvery or white underside. They are the largest of the catfish family in North America and can attain weights in excess of 100 pounds. The Maryland state record blue catfish is 84 pounds.
As an introduced species, blue catfish are now commonly found in the tidal Potomac River and some of the other tributaries of the Chesapeake Bay. Studies are currently underway to determine their impact on other aquatic species.
Flathead differ greatly in appearance from most other catfish species. Flatheads have a squarish tail, sometimes slightly notched. Their backs and sides are often an olive or light brown color with darker mottles or specks. Their bellies are often white or pale in color. Their heads are compressed, or flattened, and they have a protruding lower jaw. Flathead catfish can reach sizes in excess of 100 pounds but much smaller specimens have been encountered in the Chesapeake Bay region.
Flathead are an introduced species and are currently found in only a few places in the Chesapeake Bay; the Potomac River, Upper Bay, Elk and Sassafras Rivers.
Kusaidia kukusanya data muhimu wakati wa kushindana kwa ajili ya zawadi kubwa! Wanasayansi wa uvuvi wanahitaji msaada wa kuelewa ni aina gani za uvamizi zinazokamatwa na wapi kusaidia usimamizi wa msingi wa sayansi wa rasilimali zetu za asili. Ni Nani Awezaye Kushiriki? Mtu yeyote aweza kuingia. Washiriki wa CCA wanastahili tuzo za ziada. "Kama vile tunavyojua, ""kuvua samaki"" ni moja ya njia za kuvutia za kuvutia za iAngler, na kwa hivyo, kwa kutumia programu ya simu ya mkononi ya iAngler, unaweza kuvutia watu wengi." Kwa mfano, Maryland DNR, USFWS, na mashirika mengine ya usimamizi yatatumia data ya kile unachoona kwenye maji. Log Your Catch Kuunda akaunti ya iAngler na kupakua iAngler programu ya simu ya mkononi kuanza uvuvi na kumbukumbu ya samaki wako! (Mkubwa, ukubwa, uzito, na yaliyomo ndani ya tumbo) Ni spishi gani za uvamizi unapaswa kulenga? Mnyama huyo, ambaye alianzishwa katika eneo la Chesapeake, Marekani, mwaka 2000, anaitwa Northern Snakehead (Channa argus) na anaishi katika maji ya chini yenye joto na yenye mimea na miti iliyo chini ya maji. Wao hujivunia umbo lenye madoa linalofanana na nyoka aina ya python, na wana kichwa chenye umbo la mviringo na meno makubwa na yenye kuonekana wazi. Maelezo mengi yamefanywa kuhusu kuingizwa kwa samaki hao na hali yao ya kuwa spishi ya uvamizi. Wanasayansi wengi wanakubali kwamba utafiti zaidi utahitajiwa ili kuamua athari zozote mbaya za mazingira za spishi za nyoka zilizoingizwa Marekani. Hata hivyo, viumbe hao waliohamishwa kutoka Asia wameenea kotekote katika eneo la maji la Ghuba ya Chesapeake na idadi yao inaendelea kuongezeka. Wao ni wakubwa, wenye jeuri, wenye nguvu, na wenye ladha nzuri, na hivyo ni aina bora ya samaki wa uvuvi wa michezo. Samaki aina ya blue catfish ni ndefu na mara nyingi ni mwembamba na ana mkia uliogawanyika sana. Sehemu ya mwisho ya pua ya samaki aina ya blue catfish ni moja kwa moja, kana kwamba imepigwa kwa kisu. Spishi nyingine zote za samaki-mti zina manyoya ya pande zote mbili. Kwa kawaida samaki aina ya blue catfish huwa na rangi ya bluu-kijivu juu na sehemu ya chini ya rangi ya fedha au nyeupe. Ni moja ya samaki wakubwa zaidi katika familia ya samaki aina ya catfish katika Amerika ya Kaskazini na inaweza kufikia uzito wa zaidi ya pauni 100. Kwa mfano, rekodi ya Maryland ya samaki wa samaki wa bluu ni 84 pauni. Kwa kuwa samaki aina ya catfish ni wa asili, sasa wao hupatikana katika Mto Potomac na vijito vingine vya Ghuba ya Chesapeake. Hivi sasa uchunguzi unaendelea ili kujua athari zao kwa spishi nyingine za majini. Samaki aina ya flathead hutofautiana sana na samaki wengine wengi wa aina ya catfish. Nyani wenye vichwa tambarare wana mkia wenye umbo la mraba, nyakati nyingine wenye madoa madogo. Mara nyingi mgongo na pande zao huwa na rangi ya mzeituni au kahawia-nyeupe na madoa au madoa meusi. Mara nyingi tumbo lao huwa jeupe au lenye rangi nyeupe. Vichwa vyao vimefinyangwa, au vimegawanyika, na vina taya ya chini inayoinuka. Samaki aina ya flathead catfish huweza kufikia uzito wa zaidi ya pauni 100 lakini samaki wadogo zaidi wamepatikana katika eneo la Ghuba ya Chesapeake. Flathead ni aina ya kuingizwa na kwa sasa hupatikana katika maeneo machache tu katika Ghuba ya Chesapeake; Mto Potomac, Upper Bay, Elk na Sassafras Rivers.
