Next CHARACTERISATION Out-of A couple of ARTEMIA Communities Regarding North GREECE: BIOMETRY, HATCHING Features, CALORIC Content And Oily Acidic Users

Embolon, Thessaloniki, was in fact classified as to its means regarding breeding and you can ploidy

BOWEN, S.T., DURKIN, J.P., STERLING, G. and CLARK, L.S. (1978) Artemia hemoglobins: genetic variation during the parthenogenetic and you can zygogenetic populations. Bull., 155, 273287.

Cysts out-of parthenogenetic Artemia strains collected on Citros and you may M. Embolon saltworks inside North Greece try examined for their prospective have fun with from inside the aquaculture. The following characterizations was performed: cyst and you may naupliar biometrics, tumefaction hatching properties, oily acid reputation of nauplii, caloric stuff of nauplii stored at the twenty-five° C and in a fridge (4 8° C). The aforementioned research reveals that the 2 Artemia strains learned showcase a attributes to be used into the aquaculture, especially in culturing new-liquid varieties. Brand new biometrical analysis from cysts, nauplii and you may people shows a top degree of similarity together with other parthenogenetic strains off individuals geographical supplies, but specifically that have tetraploid Artemia from The country of spain. New Greek Artemia strains cannot be thought to be ‘provide to possess aquacultural spends unless best management of brand new saltworks was in hopes.

Since the brine shrimp Artemia try of large economic importance, you will need to evaluate the latest ‘industrial qualities of numerous populations for the possibility software during the aquaculture. Within the early in the day education, a couple of Northern Greek Artemia communities used in Citros, Piera and you will M. These were seen to be parthenogenetic and tetraploid (Abatzopoulos ainsi que al., 1986). Data out-of degree into the DNA reassociation Kinetics and on 13 enzymatic assistance of these two populations indicate that it fall into that variety (Abatzopoulos ainsi que al., 1987).


In this papers i post on the biometrical qualities regarding cysts, nauplii and you can adults, toward hatching services of cysts, i.age. hatching rate, hatching payment, hatching abilities and hatching returns, on changes in inactive lbs and you will caloric content out-of instar-We nauplii was able within room-temperature and you will cold storage criteria, and on the fresh new oily acid profiles out-of instar-We nauplii.

The two communities off North Greek Artemia evaluated come from the latest saltworks out-of Citros, Pieria (C filters), and you can regarding saltworks away from Meters. Embolon, Thessaloniki (Me strain). Cysts have been built-up when you look at the 1983, canned predicated on Sorgeloos et al. (1978), and stored in shut plastic material bags during the -25° C, getting future explore.

Adult brine shrimps have been anesthezied from inside the chlorofrom-saturated and you may measured significantly less than an excellent dissection microscope having fun with good Leitz micrometer, Another proportions was in fact performed : overall length, intestinal size, maximum depth off brood wallet, thickness out of third abdomianal section, width of lead, duration of very first antenna, maximum diameter away from state-of-the-art eye, and you can point anywhere between state-of-the-art sight (Amat, 1980). Proportions was basically did with the dogs – shot size = 50 pet-from wild cysts and you may cultured less than important labouratory criteria (yeast because food, temperature away from twenty five + 1° C, and you will seawater out of thirty-five% salinity). The info was in fact statistically handled from the investigation of covariance (Sokal Rohlf, 1981).

Hatching analyses were achieved predicated on Vanhaecke Sorgeloos (1983). Hatching efficiency, hatching commission, hatching rates and you may hatching production were analysed following the price and you may hatching returns was indeed analysed pursuing the Sorgeloos mais aussi al. (1978), Bruggeman ainsi que al. (1980), Vanhaecke Sorgeloos (1982), and you will Vanhaecke Sorgeloos (1983), respectively.

This new hatching of cysts additionally the breakup and line of the fresh new nauplii (instar-l in order to instar-III) were achieved with respect to the processes explained during the Vanhaecke age al. (1983).

This new samples of nauplii had been dried in the an enthusiastic incubator on 55°C to have forty eight hrs. For each and every naupliar stage read, 4-6 duplicated examples, of approximately ten mg deceased material have been burned entirely within the absolute oxygen and their caloric stuff was counted during the a good Phillipson microbomb calorimeter.

Prior to investigation, trials have been homogenized inside the a keen ultrasonic homogenizer (Sonifier B12) and you will complete lipids was in fact removed according to the sort of Bilgh Dyer (1959). Saponification and you will methylation were performed due to the fact described by Shauer Simpson (1978). Fatty acid methylesters was in fact injected inside the a capillary line (twenty five m fused silica; inner diameter; 0.thirty two mm; liquide phase : SILAR 10C, movie occurrence: 0.3um) installed within the a Carlo Erba Super 2350 gasoline chromatograph.
