VENICE, Italy (AP) _ City officials Wednesday issued a guide for young visitors, many of whom have been targeted by new regulations that prohibit sleeping outdoors and walking around shirtless.

Entitled ''Venice in Jeans,'' the 128-page guide costs 1,000 lire (75 cents) and lists hotels and restaurants, museums and galleries, transportation, theaters and sports activities.

Accomodtions listed range from the swank hotel Danieli, at $420 a night, to a youth hostel that costs $2 to $8 a night.

The action follows a series of measures designed to control the behavior of tourists visiting the lagoon city.

Fines of up to 50,000 lire ($38) have been levied against the mainly young tourists who camp out a night on the train station steps and in narrow alleys.

Other fines are leveled at those who play music or eat sandwiches from paper bags in main public squares or wear attire that is considered ''indecent,'' such as bathing suits or too-short shorts.
