“…These findings were similar with previous researchers. The densities for A. distans (Hsu 1999; Velasquez et al 2001), Acartia tsuensis (Ohno and Okamura 1988), Acartia sp. (Schipp et al 1999), A. royi (Cheng et al 2001), and Paracyclopina nana (Lee et al 2006) were 6.5, 2.0, 7.0, 33, and 96–119 ind./mL, respectively.…”

“…(Schipp et al 1999), A. royi (Cheng et al 2001), and Paracyclopina nana (Lee et al 2006) were 6.5, 2.0, 7.0, 33, and 96–119 ind./mL, respectively. Velasquez et al (2001) reported that better growth performance of A. distans was due to highest volume and motility of T. chuii compared to N. oculata and Dunaliella salina . The better growth and density of A. dengizicus fed on T and CT may be related to feeding behavior of this species, which preferred T due to its motility.…”

This study was carried out to investigate the effects of various diets: 4 monoalgal diets: Nannochloropsis oculata (N), Isochrysis galbana (I), Chaetoceros calcitrans (C), and Tetraselmis tetrathele (T); 4 mixed algal diets: N+I+C+T(NICT), N+I+C(NIC), C+T(CT), and I+T(IT); and 2 nonalgal diets: baker's yeast (BY) and prepared shrimp feed (SF) on population growth and density of Apocyclops dengizicus. The type and density of diet had significant effects on the growth and density of A. dengizicus (P , 0.01). Of tested diets, T and CT were optimum diets due to higher density and growth rate of A. dengizicus compared to other diets. Their high dietary value was related to the higher contents of polyunsaturated fatty acid, particularly docosahexaenoic acid (22:6n-3), eicosapentaenoic acid (20:5n-3), and arachidonic acid (20:4n-6) compared to A. dengizicus cultured on other diets. The results of the present study illustrated that T. tetrathele was the most suitable food for the culture of A. dengizicus.

“…Therefore, C. calcitrans and T. tetrathele were used for culture of A. dengizicus during their life history (including nauplii, copepodids and adults) (Farhadian 2006; Farhadian, Yusoff & Arshad 2008) as optimum diets. Better growth and development of A. dengizicus were due to the high volume and motility of T. tetrathele (Velasquez, Rosas, Carbrera, Millan & Hernandez 2001), feeding behaviour of this species, which preferred T. tetrathele due to its motility (Farhadian 2006), and biosynthesis of DHA from linolenic acid, 18:3n‐3 (Lee, Park, Lee & Kang 2006). The DHA:EPA:ARA ratios of T. tetrathele and C. calcitrans were 4.2:8.4:5.1 and 4.4:11.2:5.1 respectively.…”

The cyclopoid copepod Apocyclops dengizicus was isolated from a marine shrimp pond, Penaeus monodon, Kuala Selangor, Malaysia, and reared in the laboratory for 3 months to establish a pure population stock. Amino acids and fatty acids of A. dengizicus were determined when fed Chaetocerous calcitrans (C), Tetraselmis tetrathele (T) and their combination (CT) (1:1 by number). The protein contents in A. dengizicus that received C, T and CT were 46.8%, 60.5% and 55.3% of dry weight respectively. Correspondingly, the lipid was 19.0%, 17.8% and 19.1% of dry weight for C, T and CT respectively. The A. dengizicus cultured on C, T and CT had total essential amino acids without tryptophan measurement of 57.1, 60.3 and 67.8 and total non-essential amino acids of 42.9%, 40.0% and 32.2% of total amino acids. The fatty acid content of A. dengizicus showed that it was able to synthesize docosahexenoic acid (22:6n-3, DHA), eicosapentaenoic acid (20:5n-3, EPA) and arachidonic acid (20: 4n-6, ARA) from examined microalgal diets. The DHA:EPA:ARA ratios of A. dengizicus fed on C, T and CT were 6.8:3.0:1, 14.0:5.8:1 and 11.6:2.6:1 respectively. Apocyclops dengizicus could be suitable live food for larval ¢sh and shrimp rearing because it meets their nutritive requirements.

“…Before stocking, the seeds were first acclimated to the desired salinity by decreasing or increasing one unit per hour, and then to temperature, by placing the nauplii in 1L flask one hour prior to stocking in each tank with the corresponding temperature. Each experimental unit was stocked with one ind mL −1 for a total of 400 individuals per bottle based on the recommendations of Velásquez et al (2001).…”

This study was carried out to identify the effects of salinity and temperature during Apocyclops panamensis culture, fed with Tetraselmis chuii. The experiment was conducted in laboratory conditions for 14 days. Nauplii from the same cohort were used to start the experiment, using a density of 1 ind mL−1 in a volume of 400 mL. The feed consisted of a daily supply of 20 000 cell mL−1 of microalgae. Nine treatments with three replicates were evaluated (24◦C-28h, 24◦C-32h, 24◦C-36h, 28◦C-28h, 28◦C-32h, 28◦C-36h, 32◦C-28h, 32◦C- 32h and 32◦C-36h). The factorial ANOVA indicates that temperature had a significant effect on the abundance of total copepods at day 14 (p = 0.02), while salinity did not show a significant effect (p = 0.06) on the total population of A. panamensis. Significant effects of temperature (p < 0.01) and salinity (p < 0.001) were observed for the nauplii population. The best growth of the entire population was reached in the treatment 32◦C-28h, with a population of 1 380.95 (± 1 267.06 ind L−1 (± 1 267.06) at the end of the experiment. Treatments 32◦C-28h and 32◦C-32h produced the highest average population of nauplii and copepodites at the end of the experiment. Adult females presented the greatest abundance in the 32◦C-32h treatment with 214.29 ind L−1, adult males increased between days 11 and 14 in treatments 24◦C-28h, 32◦C-28h, and 32◦C-32h without exceeding 170 ind L−1. In this study, it is evident that A. panamensis prefers warm temperatures and brackish environments.
