OPINION
David Reynolds was convicted of fishing in closed waters in violation of 5 AAC 06.-350(b). He appeals, contending that the trial judge’s failure to require a showing of mens rea was error. We agree, and therefore reverse Reynolds’ conviction.
Reynolds is a commercial fisherman in the Bristol Bay area. On July 21, 1981, his boat drifted up the Kvichak River with the tide past two shore markers beyond which gill net fishing is prohibited. Reynolds had *1314 one drift gill net in the water. Two Fish and Wildlife Protection officers observed Reynolds’ boat as it drifted past the markers. The officers then approached the craft, asked Reynolds to pull in his net, and eventually issued a uniform summons and complaint. One of the officers testified at trial:
When we approached the boat ... we called out ‘hello’ and there was no response, so we pounded on the side of the boat, and Mr. Reynolds came out groggy and said he’d been sleeping.
Reynolds appeared pro se at trial, and he testified on his own behalf that he had no intention of drifting into the closed area. He was very tired on the evening of July 21 and decided to get some sleep. Before setting his alarm clock and lying down, Reynolds calculated his position and estimated that the boat would not drift into closed waters. His particular fear was that he might drift into the set net sites located in those waters and tangle his gear; it was this fear which caused him to make the calculations with some care.
It was not developed at trial whether Reynolds’ calculations, his fatigue, his alarm clock or some combination of these factors accounted for this somnolent transgression. The judge’s response to Reynolds’ testimony and argument was succinct:
Thank you. Fish and Game laws are just like traffic laws. It doesn’t require an intention to violate them, and so if one violates them, they’re guilty. And therefore you’re found guilty.
Reynolds was assessed a fine of $5,000 with $3,000 suspended on condition that he violate no similar laws for one year. His nets and the six fish found in them at the time of the offense were forfeited, pursuant to AS 16.05.190 and AS 16.05.195. The trial judge remarked at this time:
Now you’ve gotten a better deal than anyone else has from this court because I believe that you did it completely unknowingly. I believed you.
AS 16.05.251(2) authorizes the Board of Fisheries to promulgate regulations establishing “open and closed seasons and areas for the taking of fish.” Pursuant to this authority, the Board designated the particular waters of Kvichak Bay in which Reynolds was found as “closed waters.” 5 AAC 06.350(b). Violation of a regulation pertaining to commercial fisheries is a misdemeanor punishable by a fine of not more than $5,000 or one year’s imprisonment or both. AS 16.05.720(a). Despite the substantial nature of the penalty to which an offender is thus exposed, the regulation does not, on its face, require any accompanying mental state or criminal intent. 1 Thus, according to the view apparently held by the trial judge, proof that a defendant was in a prohibited area and that he had a net in the water 2 would make out a prima facie case that the regulation had been violated.
However, the Alaska Supreme Court has repeatedly expressed its aversion to the imposition of criminal sanctions against one who has no “awareness or consciousness of some wrongdoing.”
Speidel v. State,
Although an act may have been objectively wrongful, the mind and will of the doer of the act may have been innocent. In such a case the person cannot be pun *1315 ished for a crime, unless it is one such as the “public welfare” type of offense, which we have discussed, where the penalties are relatively small and conviction does no great damage to an offender’s reputation. Under the terms of AS 28.-35.026 there is no escape from a felony conviction and a possible five-year prison term for simple neglectful or negligent failure to return a rented automobile at the time specified in the rental agreement. To make such an act, without consciousness of wrongdoing or intention to inflict injury, a serious crime, and criminals of those who fall within its interdiction, is inconsistent with the general law. To convict a person of a felony for such an act, without proving criminal intent, is to deprive such person of due process of law.
Id.,
Hentzner v. State,
The contours of strict criminal liability were further defined in
State v. Rice,
The teaching of these cases is that strict liability is an exception to the rule that criminal intent is required. The decision whether to require that a mental state be read into a statute or regulation, even in the context of fish and game violations, must be made on a case-by-case basis.
State v. Rice,
Contrary to the state’s assertion, strict liability does not necessarily follow from either the fact that fishing is a heavily regulated activity in Alaska or that Reyn
*1316
olds entered into this activity for commercial purposes. This is not an offense like that in
Nelson v. State,
Moreover, although the regulation in question, 5 AAC 06.350(b), pertains to a traditionally regulated commercial activity, this activity is not, by its nature, restricted to large-scale, sophisticated business enterprises. Instead, the regulation applies to all commercial fishing and would include within its sweep the smallest and most casual commercial fishing enterprises. In this regard, it is significant that the regulation here has not expressly been designated as creating a strict liability offense.

Especially in the context of regulatory provisions, which can be modified or re-enacted more expeditiously and with less complexity than can formal statutory provisions, we do not think it unrealistic to expect that, if a provision is intended to create a strict liability offense, an express statement to that effect will be included. Finally, the state has not called to our attention, nor are we aware of, any legislative history indicating that 5 AAC 06.350(b) was promulgated with the intent that it be applied as a strict liability offense, precluding any defense based on reasonable mistake of fact.
Cf. United States v. Ayo-Gonzalez,
These considerations, when taken with the substantial criminal penalties available to a court in sentencing for this offense, are sufficient to convince us that strict liability is inappropriate here. We therefore hold that a showing of negligence on the part of the defendant — that he knew or reasonably *1317 should have known the location of his boat in closed waters — was necessary before a finding of guilt would be justified. Because the trial court applied strict liability in the determination of Reynolds’ guilt, we REVERSE the conviction.
Notes
. This regulation can be distinguished from those which require proof that the offender “knew or should have known” of a particular circumstance. See, e.g., 5 AAC 31.090(c); 5 AAC 32.090(c); 5 AAC 34.090(c).
. This element of the offense would more properly be designated as “fishing,” and would presumably require the present capability, such that no further act is required, to hook or trap a fish. Reynolds does not contend that his drift gill net was not, at the time of his contact with the Fish and Game officers, capable of catching a fish, so the precise definition of this element is not at issue here.
. The state argues that, if 5 AAC 06.350(b) were construed to require an element of criminal intent, enforcement of the provision would be rendered difficult because juries sympathetic to a defendant’s plight would invariably rely upon the intent requirement as a means of nullifying a generally unpopular regulation. Assuming arguendo that the state’s argument is accurate as a factual matter, it hardly seems appropriate to resolve problems in enforcement of unpopular laws by the elimination of criminal intent and the imposition of strict liability.
. We note that AS 11.81.600(b), applicable only to Title 11 but persuasive in its logic, specifically provides:
(b) A person is not guilty of an offense unless he acts with a culpable mental state, except that no culpable mental state must be proved
(1) if the description of the offense does not specify a culpable mental state and the offense is
(A) a violation; or
(B) designated as one of ‘strict liability’; or
(2) if a legislative intent to dispense with the culpable mental state requirement is present.
The revised criminal code further provides that except as described above, “if a provision of law defining an offense does not prescribe a culpable mental state, the culpable mental state that must be proved with respect to
(1) conduct is ‘knowingly’; and
(2) a circumstance or a result is ‘recklessly.’ ”
AS 11.81.610. While this scheme has removed much of the speculation about mental states under Title 11, no such relief has yet been provided under the Alaska Administrative Code or its statutory corollaries.
