Section 5 AAC 29.140 - Size limits, possession, and landing requirements(a) Unless otherwise specified in this chapter, king salmon taken and retained must measure at least 28 inches from tip of snout to tip of tail (in its natural open position) or 23 inches from the midpoint of the clethral arch to the tip of the tail. Undersized king salmon that are taken must be returned to the water unharmed. A person may not mutilate or otherwise disfigure a king salmon in any manner that would prevent the determination of the minimum size restriction specified in this section.(b) Except under a permit issued under 5 AAC 29.145(c), the heads of all adipose-fin-clipped salmon must remain attached to the fish until the fish are offloaded from a catcher vessel.(c) In waters closed to the taking of coho salmon by troll gear, a person may not use a salmon troll vessel to take salmon when coho salmon are on board that vessel.(d) If the commissioner determines that king salmon in a terminal harvest area are predominately Alaska hatchery-produced, the commissioner may close, by emergency order, a salmon troll fishery in a terminal harvest area and immediately reopen a season during which king salmon no less than 26 inches in length may be retained.(e) A salmon troll permit holder is not required to offload salmon other than king salmon at the end of a king salmon fishing period. In addition to the requirements of 5 AAC 29.145, a fish ticket must be submitted to the department within seven days after offloading king salmon that includes an estimate of the number and pounds of salmon that remain on board the vessel and a notation that the estimated fish have not been offloaded.Eff. 10/1/98, Register 147; am 7/26/2003, Register 167Before Register 147, Oct. 1998, the substance of 5 AAC 29.140 was contained in former 5 AAC 30.392(a) and (c), 5 AAC 30.393, 5 AAC 33.392(a), (d) and (f), and 5 AAC 33.393.
