Plaintiffs are commercial perch fishermen who pursue this occupation in the Saginaw Bay area. In the summer of 1965, officers of the Michigan Department of Conservation* seized certain catches of perch taken by the fishermen on the basis that the fish were undersize and, therefore, illegal under MCLA 308.14(d); MSA 13.1505(d).
Plaintiffs instituted suit in the Court of Claims seeking $6,000 in damages, alleging that the fish had been illegally confiscated by representatives of the state. Both parties moved for summary judgment, and the Court of Claims granted defendant’s motion *498for summary judgment. A majority of the Court of Appeals reversed* holding that the Court of Claims improperly interpreted MCLA 308.14(d); MSA 13.1505(d), and that, in addition, the state failed to follow the proper statutory condemnation procedure provided by MCLA 300.1 et seq.; MSA 13.1211 et seq. The Court of Appeals remanded to the Court of Claims with an order to that court to grant, upon motion, a change of venue to the appropriate circuit court to make determination of whether the fish met the weight requirements of MCLA 308.14(d); MSA 13.1505(d). The majority opinion of the Court of Appeals held that if it was found that the weight requirement was met, the circuit court should find that the Department of Conservation wrongfully confiscated the property and that plaintiffs would be entitled to damages, since it w’as no longer possible to return the property. Judge1 McGregor dissented, holding that the opinion of the Court of Claims should be affirmed. 28 Mich App 181. We granted leave to appeal. 384 Mich 805.
Two basic issues are presented in this appeal: The first involves the interpretation of MCLA 308.14(d); MSA 13.1505(d). Plaintiffs contend that if the defendant is correct in its interpretation of this statute, such interpretation would violate the equal protection provisions of the United States Constitution and the Michigan Constitution. The second issue is whether the Court of Appeals was correct in its ruling that the state should follow the statutory condemnation procedures provided by MCLA 300.1 et seq.; MSA 13.1211 et seq.
MCLA 308.14(d); MSA 13.1505(d), provides:
“It shall be unlawful to market, have in possession, transport or offer for sale at any time in this *499state, whether caught within or without this state, any: . * # *
“(d) Perch, of a less length than 8 1/2 inches in the round and filleted perch of a less weight than 1 3/4 ounces; perch with heads and tails off of a less length than 5 1/2 inches; * * *
“The measurement of the length of a fish within the meaning of this act shall be taken in a straight line from the tip of the snout to the utmost end of the tail fin. For the purpose of this act a ‘fish in the round’ shall be deemed to be a fish that is entirely intact as it was taken out of the water with no part removed by dressing. A ‘dressed fish’ shall be deemed a fish with the head attached but with the gills and the entire gut or viscera (stomach, liver, intestine, gonads) removed, and a ‘filleted fish’ shall be deemed to be a fish with the entire head, gut or viscera, gills, bones, scales and all fins removed. The measurements of length and weight as prescribed in this act shall apply without any allowance made for the shrinkage of the fish.”
It is well settled that the proper construction of any statute is for the court. Albert v Gibson, 141 Mich 698 (1905); Smith v City Commission of Grand Rapids, 281 Mich 235 (1937); Webster v Rotary Electric Steel Co, 321 Mich 526 (1948). The purpose of the court in interpreting a statute is to give effect to the legislative intent. People v Gould, 237 Mich 156 (1926); Attorney General, ex rel Whitcomb, v Lau, 256 Mich 13 (1931); Bankers Trust Co of Detroit v Russell, 263 Mich 677 (1933); Ballinger v Smith, 328 Mich 23 (1950). If there is a conflict, the spirit and purpose of the statute should prevail over its strict letter. Stambaugh Twp v Iron County Treasurer, 153 Mich 104 (1908); Smith v City Com*500mission of Grand Rapids, supra; Webster v Rotary Electric Steel Co, supra.
Both, parties have discussed the issue of whether that part of the statute reading:
“Perch, of a less length than 8 1/2 inches in the round and filleted perch óf a less weight than 1 3/4 ounces;” (Emphasis added.)
should be read in the disjunctive or conjunctive. In Klug v Auditor General, 194 Mich 41, 45 (1916), the Court stated:
“Relator’s position is based largely upon the punctuation and upon rules of grammatical construction, and while these rules have been applied for the purpose of ascertaining the meaning of a statute, nevertheless they must yield to a clearly disclosed legislative intention.”
In Heckathorn v Heckathorn, 284 Mich 677, 681 (1938), the Court said:
“The popular use of ‘or’ and ‘and’ is so loose and so frequently inaccurate that it has infected statutory enactments. While they are not treated as interchangeable, and should be followed when their accurate reading does not render the sense dubious, their strict meaning is more readily departed from than that of other words, and one read in place of the other in deference to the meaning of the context.”
See, also, L. A. Darling Co v Water Resources Commission, 341 Mich 654, 662 (1955).
The preamble of The Commercial Fishing Law (MCLA 308.1 et seq.; MSA 13.1491 et seq.) clearly expresses the legislative intent to protect and preserve the fisheries of the State of Michigan. Thus, conservation is the legislative intent of this enactment and, indeed, both parties agree with this proposition. The State of Michigan was attempting *501to protect the fisheries by insuring that undersize fish would not be removed from the waters. The statute clearly sets up three separate tests to determine the unlawful possession of perch: (1) if they are of a less length than 8-1/2 inches in the round; (2) if when filleted they are of a less weight than 1-3/4 ounces; and (3) if when the head and tails are removed, they are of a less length than 5-1/2 inches.
We agree with the construction of the statute given by the Court of Claims and disagree with that of the Court of Appeals. The test provided by the Court of Appeals would require the Department of Conservation to fillet and weigh every one of the fish caught that were of a less length than 8-1/2 inches. We believe a careful reading of the statute indicates that the Legislature intended to set up three separate tests. The different tests were to be utilized depending upon the condition in which the perch were found by the Department of Conservation. The Department of Conservation would not have to weigh the fish unless they were found in a filleted state. If the fish failed to meet any one of the three tests, then the possession would be illegal. We, therefore, hold that the Court of Appeals erred in its interpretation of the statute.
Plaintiffs contend that if the Court of Claims was correct in its interpretation of the statute, that the application of the statute to them was unconstitutional as a violation of the Equal Protection Clause. The Court of Appeals in its opinion correctly pointed out that the plaintiffs’ constitutional rights would not be violated unless the statute gave them explicit statutory right to have possession of the fish. The Court stated (pp 183-184):
“In order for the plaintiffs to maintain a cause of action upon which relief could be granted, it is neces*502sary to establish that they either had legal title to, or a right to possession of, the fish. It has long been recognized that animals ferae naturae are not objects of private ownership, but rather belong to the state, which in effect holds the fish in a trust for all of the people of the state in their collective capacity. See Geer v. Connecticut (1930), 161 US 519 (16 S Ct 600, 40 L Ed 793); Fleming v. United States (Ct Cl, 1965), 352 F2d 533; People v. Zimberg (1948), 321 Mich 655; People v. Collison (1891), 85 Mich 105. The state, representing the people, has the authority to regulate or even prohibit the taking of animals ferae naturae if such action is deemed necessary for thd public good. See People v. Dornbos (1901), 127 Mich 136; People v. Lassen (1906), 142 Mich 597.
“In People v. Zimberg, supra, p 658, the Court stated:
“ ‘It is universally held in this country that wild game and fish belong to the State and are subject to its power to regulate and control; that an individual may acquire only such limited or qualified property interest therein as the State chooses to permit. In People v. Soule (1927), 238 Mich 130, we said:
“ ‘ “This conservation legislation is clearly an exercise of the police power inherent in the State. The wild game and fish (ferae naturae) within its confines belong to the State. No private ownership or private property rights are involved in this inquiry, McKenny v. Farnsworth (1922), 121 Me 450 (118 A 237).” ’
“Since the fish belong to this state, it becomes clear that the commercial fishermen may acquire only such right to possession or ownership of the fish as the state may allow. Thus, for the plaintiffs to be in lawful possession of the fish it is imperative that they comply with the regulations which the state has promulgated under the authority of its police power.”
*503Thus, because fish are ferae naturae, they are property of the state, unless otherwise provided by the statute. Plaintiffs were not denied the equal protection of the laws.
In view of our disposition of this issue, the second issue raised by the Court of Appeals concerning the proper procedure on remand becomes moot and, therefore, will not be dealt with in this decision.
The judgment of the Court of Appeals is reversed and the judgment of the Court of Claims is affirmed. Costs to defendant.
T. M. Kavanagh, C. J., and Black, Adams, T. G. Kavanagh, and Williams, JJ., concurred with Swainson, J.By virtue of PA 1968, No 358 (MCEA 16.350; MSA 3.29[250]), the Department of Conservation became the Department of Natural Resources. We shall refer to it as the Department of Conservation in this opinion.
