Experiments which used crossbred cows and heifers, from peer review publications originating from the Karnataka Veterinary, Animal and Fisheries Sciences University (Bidar) and Veterinary College (Bengaluru) in India were used to determine if ruminal microbial N (MN) supply could be predicted based upon the partitioning factor (PF, mg in vitro true digested organic matter: ml gas) of the diets fed to the cattle, their rate of gas production in vitro (k, /h,) as well as the neutral detergent fibre (NDFom) and crude protein levels of the diets. The MN supply to the duodenum was quantified based on allantoin excretion in urine. The five published experiments included 15 treatment groups. Multiple correlation analysis showed that the quadratic component of diet NDFom (P=0.02) and the linear (P<0.01) and quadratic (P<0.01) components of diet k (i.e., r2=0.87) predicted supply of microbial N (MN) to the duodenum according to the equation: MN (g/kg ADOM)=-25.7+(1402*k)-(10177.4*k2)-(0.0000163*NDFom2) [SEP=0.81], where k is in unit/h and NDFom is g/kg DM. Residuals of predicted versus actual MN values showed equal distribution. Changes in predicted values of MN were judged to be consistent with our understanding of their function in the rumen, as well as quantitatively consistent with published values determined in vivo. Overall, according to the prediction equation, supply of MN increases with increasing low levels of NDFom in the diet, but is maximized at all dietary NDFom levels with a dietary in vitro rate of gas production of 0.065-0.070/h. Results support utilizing in vitro rate of gas production in diet formulation, but not PF, although research with higher production ruminants is warranted. © 2010 Elsevier B.V.

Food security is a major concern for all countries in the face of population increase and diminishing energy and water supplies. Over one billion people in low and middle income countries suffer from malnutrition. To meet the UN Millennium Development Goals to eradicate hunger and poverty, it is essential to reduce post harvest losses, including in the fisheries sector. The overall objectives of SECUREFISH are to strengthen capacity in low cost technology; to improve the preservation of existing fish supplies; to utilise waste and bycatch to produce value-added products; to develop an integrated quality management tool and finally to test the developed technology and quality management tool in different real third country conditions. There are six work packages (WP). WP1 will ensure the efficient management of the project. WP2 will develop low cost innovative processing tools based on traditional technology for preserving fish including a solar tunnel drier, a modified solar assisted extruder and fast freezing/ continuous atmosphere freeze-drier (CAFD). In WP3, underutilised bycatch and waste by-products of fish processing will be recovered and converted to high value products. WP4 will develop an effective total quality management tool (safety and risk assessment; HACCP quality cost and traceability, nutritional and eating quality and carbon footprint) of three fish product chains (solar dried, extruded and frozen/CAFD) which will be tailored to suit local needs. The technological advances (WP2) and quality management tool (WP4) will be evaluated in the three fish product chain case studies in Africa (Kenya, Namibia, Ghana), Asia (India and Malaysia) and Latin America (Argentina) to include different economic, cultural and social conditions. The case studies involve stakeholders including SMEs to ensure sustained implementation of project results. WP6 details a strategy for education, training and dissemination to widely promote the results and guidelines.

Vibrios belonging to the Harveyi clade are pathogenic marine bacteria affecting both vertebrates and invertebrates, thereby causing a severe threat to the aquaculture industry. In this study, the expression of haemolysin, metalloprotease, serine protease, the quorum sensing master regulator LuxR and the virulence regulator ToxR in different Harveyi clade isolates was measured with reverse transcriptase real-time PCR with specific primers. There was relatively low variation in the in vitro expression levels of the quorum sensing master regulator luxR (sevenfold), whereas for the other genes, the difference in expression between the isolates showing lowest and highest expression levels was over 25-fold. Furthermore, there was a significant correlation between expression levels of toxR and luxR and between the expression levels of these regulators and the protease genes. The expression levels of luxR, toxR and haemolysin were negatively correlated with the survival of brine shrimp larvae challenged with the isolates. Finally, a non-virulent, a moderately virulent and a strongly virulent isolate were selected to study in vivo expression of the virulence genes during infection of gnotobiotic brine shrimp larvae. The in vivo gene expression study showed a clear difference in virulence gene expression between both virulent isolates and the non-virulent isolate. © 2010 Society for Applied Microbiology and Blackwell Publishing Ltd.

Infectious hypodermal and hematopoietic necrosis virus (IHHNV) of shrimp, recently been classified as Penaeus stylirostris densovirus (PstDNV). The complete nucleic acid sequence of PstDNV from India was obtained by cloning and sequencing of different DNA fragment of the virus. The genome organisation of PstDNV revealed that there were three major coding domains: a left ORF (NS1) of 2001. bp, a mid ORF (NS2) of 1092. bp and a right ORF (VP) of 990. bp. The complete genome and amino acid sequences of three proteins viz., NS1, NS2 and VP were compared with the genomes of the virus reported from Hawaii, China and Mexico and with partial sequence available from isolates from different regions. The phylogenetic analysis of shrimp, insect and vertebrate parvovirus sequences showed that the Indian PstDNV isolate is phylogenetically more closely related to one of the three isolates from Taiwan (AY355307), and two isolates (AY362547 and AY102034) from Thailand. © 2011 Elsevier B.V.

The complete nucleic acid sequence of the Penaeus monodon densovirus (PmDNV) from India was characterized. Analysis of the whole genome, consisting of 6310. bp revealed the presence of three open reading frames (ORFs), comprising 1281. bp, 1734. bp and 2460. bp, respectively. The complete genome and amino acid sequences of three proteins viz., NS1, NS2 and VP were compared with PmDNV from Thailand, PmergDNV from Australia and other partial sequences in GenBank, respectively. Highest nucleotide similarity was observed with the Thai strain (88%), while 33, 32 and 91 amino acid substitutions were observed in the NS2, NS1 and VP, respectively. Phylogenetic analysis of shrimp, insect and vertebrate parvovirus sequences revealed that the Indian PmDNV is more closely related to Thai isolates than all other parvoviruses reported so far. © 2010 Elsevier B.V.

The transglutaminase (TGase) enzyme from four different fish species, namely bigeye snapper, Indian oil sardine, tilapia and common carp have been isolated and characterised. The specific activity of the enzyme was higher in tilapia followed by oil sardine, common carp and bigeye snapper. The molecular weight of pure TGase was found to be in the range of 73-95 kD for four different fish species. The temperature optima for maximum activity of TGase varied amongst four species studied. The effect of activator (calcium chloride) and inhibitors (ethylenediaminetetraacetic acid (EDTA), ammonium chloride and free lysine-hydrochloride) at different concentrations on the TGase enzyme activity have been evaluated. The addition of isolated TGase to fish mince from Cynoglossus sp. was attempted in order to evaluate the setting and gelling ability. The setting and gelling ability of fish mince in presence of TGase improved considerably as revealed by small strain and large strain test. © 2011 Elsevier Ltd. All rights reserved.

Macrobrachium rosenbergii nodavirus (MrNV) is responsible for the newly emerging catastrophic disease known as white tail disease (WTD) in M. rosenbergii. The complete sequence of RNA2 (1175. bp) and 3126. bp region of RNA1 of an Indian strain of MrNV was generated. Sequence analysis of RNA2 revealed the presence of a single ORF encoding a capsid protein of 371 amino acids with a predicted molecular mass and p. I of 41.5. kDa and 8.97 respectively. RNA1 contained two ORFs, one encoding a partial RNA dependent RNA polymerase (RdRp) of length 1034 amino acids and another a B2-like protein with a length 133 amino acids. A phylogenetic analysis based on the amino acid sequence of the capsid protein, to related nodavirus sequences suggests the establishment of new genotypes within the Nodaviridae family and we suggest the name should be genus Gammanodavirus. A new reverse transcriptase-polymerase chain reaction (RT-PCR) assay has been developed and optimized for the detection of shrimp nodavirus with a sensitivity to detect up to 24 copy numbers of plasmid construct. © 2013 Elsevier B.V.

The bacteria Vibrio parahaemolyticus is an important component of coastal ecosystems worldwide, and in recent years, V. parahaemolyticus has caused several cases of food-borne gastroenteritis. However, research investigating which parameters are important in regulating V. parahaemolyticus abundance in tropical areas with relatively stable temperatures and salinity are largely lacking. The objective here was to investigate which environmental forces are driving elevated abundances of V. parahaemolyticus in a tropical oligotrophic coastal area in the Arabian Sea. We analysed a large number of environmental parameters in parallel with cell densities of V. parahaemolyticus and Vibrio spp. Abundance data was obtained using real-time PCR, during two different sampling periods, representative for two distinct seasons. Water temperature and salinity were stable during and between sampling periods, but V. parahaemolyticus abundances were on average six times higher during the first sampling period in December, compared to the second period in February-March. V. parahaemolyticus abundance was found to be positively correlated to inorganic phosphate concentration and copepod abundance. We thus hypothesise that these are important factors regulating V. parahaemolyticus abundance in coastal tropical areas during these periods. © 2013 Springer Science+Business Media New York.

The swim bladders of fresh water carps are small in size and normally discarded. The utilization of swim bladders for the preparation of gelatin will open up a new avenue for a better disposal of carps processing waste and good returns for aquaculturist. In the present study, gelatin was prepared from the swim bladders of Catla catla (Catla) and its physicochemical and rheological properties have been assessed. The yield of gelatin from the swim bladders was 13.5% (w/w). The amino acid profile of the gelatin revealed a high proportion of glycine and imino acid residues. SDS-PAGE pattern of the gelatin revealed two major bands corresponding to a α-chain and cross-linked component (β-chain). The Bloom strength of solidified gelatin was 264.6g. The gelling and the melting temperature of gelatin were 13.7°C and 23.3°C respectively as determined by Controlled Stress Rheometer. The flow properties of gelatin solution revealed non-Newtonian behaviour with shear thinning phenomenon. The thixotropic area of flow curves increased with the temperature at any given concentration studied. The Casson and Herschel-Bulkley models were suitable to study the flow behaviour of gelatin solutions. The Arrhenius model was used to describe the temperature dependency of viscosity. The activation energy (Ea) of the gelatin was proportional to the concentration. © 2015 Elsevier Ltd.

Water samples and plankton net hauls were collected 24 times from Gullmar Fjord on the Swedish west coast from February 2004 to March 2005. The abundance of Skeletonema marinoi was estimated and individual clones isolated. Abundance was highest during the spring blooms in February to March. Subsequently, S. marinoi was detected in all samples but at lower abundances. At the end of September a second peak was recorded. All clones were pre-adapted to the same culturing conditions for more than 1.5 years. Large subunit (LSU) rDNA (D1-D3) was sequenced from 23 clones isolated from three different seasons, February, June and September. Six microsatellite loci were genotyped for 19 clones to estimate within-season genetic diversity. Three clones from each season were selected for physiological experiments at different salinity and temperature combinations and monitored for average number of divisions per day, maximum cell densities, biovolume, and total RNA concentration per cell. Differentiation of physiological response among the clones was partly attributed to the month of isolation. The February isolates had a significantly higher division rate and larger biovolumes, while the September clones attained higher cell densities. The June clones were isolated during the time of the year when the natural abundance is lowest, and exhibited the smallest genetic and physiological variation, which suggests that they were under strong selection pressure. The differential physiological responses and degree of genetic heterogeneity among seasonally separated clones could indicate that different populations succeed each other in the fjord. © 2010 British Phycological Society.
