    Abstract: Isolated DNA from Penaeus vannamei was digested with restriction enzymes, restriction fragments of genomic DNA inserted into a plasmid vector and screened for recombinant plasmids containing repeated sequences. Ten of the resulting isolates contained representatives of the same repeated element, a satellite sequence present in one or more blocks of tandemly repeated units. The cloned repeat units range in size from about 100 to 200 base pairs, more typically between about 139 to 188 base pairs. Embedded within each cloned repeat unit are 6 to 15 copies of a tandemly repeated pentanucleotide microsatellite. The genome of P. vannamei contains approximately one million copies of this satellite/microsatellite unit. The sequences are useful as markers for the selection of shrimp having a genetically-transmitted favorable growth characteristic, such as increased reproduction, enhanced growth rate, increased size, disease-resistance, and the ability to grow in colder waters, for improved aquacultured shrimp production. Hybridization of the marker to an isolated Peaneus shrimp mucleic acid molecule can be used to identify species, strains or individual shrimp having the desired characteristics. Once identified, these shrimps can be bred to shrimp having the same or an additional desired characteristic to produce a high quality, genetically superior seedstock or larvae useful for the economic production of farmed shrimp.

    Abstract: A method for the selection of shrimp having a genetically-transmitted favorable growth characteristic for improved aquacultured shrimp production. A genetic marker for the favorable characteristic is prepared by isolating (Penaeus) shrimp nuclear DNA by extraction with chloroform in the presence of cetyl trimethyl ammonium bromide, digesting the DNA with one or more restriction enzymes, and identifying characteristic restriction fragments. The marker is hybridized to a nuclear nucleic acid molecule isolated from (Penaeus) shrimp for the selection of shrimp having the desired characteristic. The marker can be a labelled probe or a primer for amplification and subsequent detection of a gene that encodes a protein promoting the desired growth characteristic. The selected shrimp can be used to produce a high quality, genetically superior seedstock or larvae useful for the economic production of aquacultured shrimp.

    Abstract: A pH-measuring method and device (50) for monitoring and then correcting for electrode drift is provided. The device includes a pH-measuring electrode (54) and more than one reference electrodes (52a-52e). During operation, the pH-measuring device is placed in contact with a sample (51). The pH value measured at each electrode pair is due to the electrical potential difference between the pH electrode and the reference electrode. The maximum and minimum pH values are determined, and then the remaining pH values are averaged together to generate an overall average pH. The maximum and minimun pH values are subtracted from the average pH to generate a difference which is then compared to a user defined drift level to determine if a particular electrode is deficient. The pH values from deficient electrodes are not considered when the overall pH of the sample is determined.
