This is what TSA has to say : http://www.tsa.gov/travelers/airtrav...rial_1188.shtm. Basically, the agency says about rods: "Fishing Rods are permitted as carry-on and checked baggage. However, please check with your air carrier to confirm that it fits within their size limitations for carry-on items. Ultimately, it is the carrier's decision as to whether or not it can be transported as carry-on baggage." And here is what the agency says about tackle, including fish hooks: "Fishing equipment should be placed in your checked baggage. Some tackle equipment can be considered sharp and dangerous. Expensive reels or fragile tackle such as fly's [sic] should be packed in your carry-on baggage."
