“…Surviving larvae and post-larvae were examined and classified according to shell growth (Leighton 1974;Searcy-Bernal et al 1992). Five to 10 larvae were examined at each stage of shell growth and the development of the radula determined using a radula squash preparation ).…”

This paper describes studies on the settlement of the abalone Haliotis australis Gmelin. Ten-day-old H. australis larvae had a slower rate of settlement than 5-day-old larvae. A high proportion of veliger larvae had the ability to prolong the searching phase of settlement and delay metamorphosis, even over prepared settlement surfaces but radula development continued at a similar rate in both settled and swimming larvae. In any one batch of larvae settlement was slow and asynchronous and post-settlement survival was low. Light was shown to influence the swimming behaviour of larvae in settlement tanks, with more larvae swimming in the dark than in the light. The implications of these behaviours are discussed in relation to larval and postlarval energetics and feeding.

Although all dietary treatments resulted in a good survival at competence, significant difference in post-larval survival was observed between treatments, and indeed, only larvae fed Duna and CD survived to 180 days post settlement (DPS).In the second experiment, the settlement substrates consisted in a film of cultured Ulvella lens or a naturally developing biofilm of diatoms, and the employed rearing water was either natural seawater or seawater previously exposed to P. lividus adults. At 10 DPS, larger (p<0.05) post-larvae were observed in the natural biofilm treatment, whilst the presence of conspecifics significantly increased larval settlement in both substrates (p<0.01).These results indicate that it is important to consider the survival of post-larvae and juveniles to establish the efficiency of the dietary treatment on the hatchery production of P. lividus. Furthermore, it suggests that improved settlement protocols, such as the use of conspecifics, could contribute to increase hatchery outputs. Finally, it confirms the suitability of U. lens as settlement cue but also highlights that further research is required to establish its effectiveness for post-larvae first feeding.

“…Reported 48-h EC 50 values were 33-45.9 mg/l for DMP, 52-86 mg/l for DEP LeBlanc 1980), 3.0-5.2 mg/l for DBP (McCarthy and Whitmore 1985;Scholz 1994), and 3.7 mg/l for BBP (Gledhill et al 1980). Toxicity tests of PAEs have also been performed with invertebrates Hyalella azteca, Chironomus tentans, and Lumbriculus variegates.…”

“…The slides with diatoms and bacteria films were prepared by placing them in an aeration tank containing SFS and diatoms (obtained from an abalone culturing farm in Dapeng Bay) for 24 h. The percentages of settled larvae and fully metamorphosed larvae on the slides were recorded after another 84 h of incubation. Therefore the total exposure time for the completion of larval metamorphosis was 96 h. Fully metamorphosed larvae were identified when the peristomial shell appeared (Searcybernal et al 1992;Gapasin and Polohan 2004 Two liter of SFS taken from Dapeng Bay was firstly filtered through Whatman GF/B filter paper (1 lm), and then extracted with 20 ml hexane for two times, and all the hexane was collected together. The mixed hexane was evaporated under nitrogen to 0.5 ml, and then analyzed by means of a GC-2010 gas chromatography (Shimadzu, Japan) coupled to a mass selective detector.…”

Toxicity of seven phthalate esters to embryonic development of the abalone Haliotis diversicolor supertexta

The toxicity of seven phthalate esters (PAEs), dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), butylbenzyl phthalate (BBP), di-n-hexyl phthalate (DnHP), di-(2-ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DOP) to embryogenesis and larval development of the marine univalve Haliotis diversicolor supertexta was examined by means of two-stage embryo toxicity test. At the blastula stage, the normal embryonic development of H. diversicolor supertexta showed a good dose-response decrease when exposed to DMP, DEP, DBP, BBP, and DnHP. 9-h EC(50) values of DMP, DEP, DBP, BBP, and DnHP were 55.71, 39.13, 8.37, 2.65, and 3.32 mg/l, respectively. 9-h EC(50) values of DEHP and DOP were not available due to their low solubility. The toxicity order of seven tested PAEs was BBP>DnHP>DBP>DEP>DMP>DOP>DEHP. With the completion of metamorphosis as an experimental endpoint, the 96-h no-observed effect concentration values of DBP, DEHP and the other five tested PAEs were 0.022, 0.021, and 0.020 mg/l, respectively. Due to simple obtainment, convenient stimulation to spawn in the lab, greater sensitivity than mature species, and short culture time, the embryos of H. diversicolor supertexta have the potential to be utilized in acute toxicity test for at least PAEs.
