female bonytail were spawned over a four-week period utilizing CP to induce egg ovulation; 11 were spawned in 1984. Spawning and hatching techniques utilized were the same as those reported for Colorado squawfish except that jars were not tested. In 1983 female bonytail had a mean weight of 0.28 pounds. Number of eggs taken per individual ranged from 1,015 to 10,384; mean egg take was 4, 677. Average number of eggs per pound of body weight varied from 5,075 to 29,930 with a mean of 17,280; egg viability averaged 67.5%. Fry were distributed to the AGFD and the California Department of Fish and Game (CDFG). In 1984, the females averaged 0.72 pounds and produced 23,940 eggs per pound of body weight. Total egg take was 181,108 and mean number of eggs per female 16,464. Fry were shipped to CDFG. Although bonytail were not spawned artificially in 1985, the fish spawned naturally in holding ponds and when the broodfish were moved in early fall, 12,618 four-inch fingerlings were removed and later stocked in Lake Mohave, AZ. We are maintaining 494 four-year-old brood and 1,424 excess fish that are scheduled for "experimental" stocking in Arizona waters in 1986 or 1987. Woundfin Woundfin spawning was examined in 1984. Both natural and hormone induced spawning were attempted; greatest success was achieved through natural spawning on a prepared gravel bed (size range 1/4" - 5"). Current was provided by flowing water through a plugged 2" black plastic pipe with 1/8" holes drilled in it to pass water somewhat uniformly over the gravel bed. Seventy adult woundfin were placed in the spawning pond and 64 brought to the holding house for spawning studies. Sexing woundfin was difficult and no technique was fully reliable. Males averaged 4.97 grams and were injected with CG to enhance milt production. Twenty females (averaging 6.44 gms) were injected with CP to induce egg ovulation and handstripped 24 hours later; twelve (60%) spawned successfully. Total number of eggs produced was 2,067 and mean number of eggs taken per female was 172. A total of 1.,163 swimup fry were recovered and stocked along with fry produced by natural reproduction in the ponds. A total of 3,500 woundfin ::ere recovered in late summer. Summary Between 1981-1985, Dexter NFH personnel distributed 8,766,037 fry, 790,772 fingerling and 282 adult razorback sucker into historic habitats in Arizona. During the same period 116,638 Colorado squawfish fingerlings were stocked in the mainstream Colorado River near Grand Junction, CO and 116,789 fingerlings and 301 subadults (4 year olds) stocked into Arizona waters (Salt and -40-
