The mutton snapper Lutjanus analis is an overexploited species of economic importance for the Northeast region of Brazil. To determine the reproductive aspects of the mutton snapper, biological data were sampled from Bahia, Pernambuco, Paraíba, Rio Grande do Norte and Ceará States, between 7 and 200m depth, from February 1997 to December 1999, performed in the Brazilian Economic Exclusive Zone ...

BACKGROUND Commercial sheep raised for mutton grow faster than traditional Chinese sheep breeds. Here, we aimed to evaluate genetic selection among three different types of sheep breed: two well-known commercial mutton breeds and one indigenous Chinese breed. RESULTS We first combined locus-specific branch lengths and di statistical methods to detect candidate regions targeted by selection in...

Riley’s Hump, in the recently created South Tortugas Ecological Reserve, is the historical site of a spawning aggregation of mutton snapper (Lutjanus analis), perhaps the only site in the southeastern United States. The aggregation was exploited heavily by commercial fishermen for decades prior to the area being declared an ecological reserve in 2001. Fishery managers hope that the population o...

AIMS The potential use of bifidobacteria as indicators for faecal contamination was studied along a sheep meat production and processing chain. The levels of bifidobacteria were compared with those of Escherichia coli. Total viable counts were followed along the chain (244 samples). METHODS AND RESULTS Forty-three per cent of the samples contained bifidobacteria, of which 15% were solely dete...

The presence of trace quantities of odd-numbered iso and anteiwo branched-chain fatty acids in hydrogenated mutton fat has been established by the isolation of 13-methyltetradecanoic acid, (+ )-12-methyltetradecanoic acid, (+ )-14-methylhexadecanoic acid and 10-methyldodecanoic acid (Hansen, Shorland & Cooke, 1953, 1952, 1954a). In the present paper is reported the isolation from hydrogenated m...

The purpose of the present study was to compare the abilities of University of Vermont Broth (UVM) and 0.1% (w/v) peptone water for recovering Listeria monocytogenes from various foods. A total of 210 food samples (raw fish-100, mutton-60, paneer-50) was taken and pre-enrichment was carried out in UVM broth and 0.1% (w/v) peptone water. A total of five isolates were recovered, three from mutton...
