Animal Culture | Fathead minnows (Pimephales broaelas) were reared in continuously flowing veil vater at Haskell Laboratory^Adult fish resided in 38 L aquaria at approximately 258C and were fed frozen brine shrimp (Artemia sp., Golden Gate Brand, Korden Division, Novaiek, jinc., Hayward, CA) generally twice daily, once on Saturday, and not on Sundays. | Eggs were deposited on polyvinyl chloride tiles coated with sand. Tiles vijth eggs were aerated and incubated at approximately 25C in a water bach. Larvae were reared in 22 L aquaria at approximately 22C and were fed newly hatched Artenia generally twice daily on weekdays and daily on weekends. jJuveniles were held in a 22 L aquaria at approxiaately 22 C and were fed newly hatched Arteaja and/or frozen brine shrimp generally twice daily on weekdays and once on Saturday and Sundays. No treatment of the fish for-diseases was required during the holding period. Sickness, injury, and abnormality were not observed. Animals were identified by labels on aquaria and test vesjsels. D. Test Methods [1] Five test concentrations and i water control were used. Nominal test concentrations were 648, 1080, 1800, 3000, and 5000 mg/L. The fathead minnows ranged from 1.5 to 2.4 cm in staniard length (mean 1.9 cm) and 0.029 to 0.16 g in weight (mean 0.092 g). The fathead minnows were 85-86 days old at test start. Glass aquaria (5-L) containing 4 L of test solution (approximately 12-cm liquid depth) were employed. TWO! replicates of each test concentration with ten fish per relicate were used. Fish were added to the test concentrations using random numbers and were not| fed for 48 hours prior to the test nor during the test* Mean loading for controls at test conclusion was 0.23 g/L. Test solutions were held between 20.7 tmd 21.6BC (mean 21.2C) and were unaerated, until at approximately 72 hours wnen low dissolved oxygen levels necessitated the use of gentle aeration (approximately 120 bubbles/minute). A photoperiod of 16 hours light (215 Lux) versu^ 8 hours darkness was employed.

JffiSULTSAND DISCUSSION i A 96-hour rangeflnding stud;r was conducted using the following concentrations; water control, : .0, 10, 100, and 1000 ng/L. observed at any test concentrat: on. Mortality was not Nominal^HPHH^lconcenttationswere 649, 1080, 1800, 3000, end 5000 ng/L. All test concentrations (excluding control) were cloudy throughout the testing period. All chemical and physical parameters (Tables 2 and 3) were within expected ranges, except dissolved oxygen;in replicate A of the 5000 mg/L test concentration at 72 hours. The(dissolved oxygen value (5.3 mg/L) dropped slightly below 60X of the theoretical saturation value of 9.0 mg/L at 21C. As a result, all test concentrations were gently aerated beginning at 72 hours (approximately 120 bubbles/minute). This apparent decrease in dissolved oxygen was not considered biologically'significant based on the lack of observed mortality. No mortality or sublethal effects were seen in any test concentration (Table 4). The 9^-hour LC50 based on nominal concentrations was greater than 5000 mg/L, the highest concentration tested. ^1.1. CONCLUSION Q^BIHHQwas not acutely toxic to juvenile, fathead minnows (Pimephales promelas) in a 96-hour aerated, static, test. The 96-hour LC50 based on nominal concentrations was greater than 5000 mg/L, the highest concentration tested. | ie x : Ce | LE iS CI [ p | Eo as RRR * 5 ee RN Ad: Pe SMe ; Son Ro | 5 SP EEn 2 | se fgetsSeo NG eae fey BE ORSe RE Eh a a Sate : fs | Em SiC a : CEE Ee A a | ae es a | LBeH LiE nn ieae oo | in de H e ee Eo el t TC H T : oT SF | | es Iirl ln wa59 Eded be ae ^-"-sWw'y" '-^%OiSi5'!'?i'!,SM ' ' :%?^";.;5;"^'''3^W .
