Seasonal dynamics of phytoplankton in relation to environmental factors in the Maheshkhali channel, Cox's Bazar, Bangladesh

In total 68 phytoplankton species were identified at the mouth of the Maheshkhali channel with the Bay of Bengal, among them 41 belong to Bacillariophyceae, 17 Dinophyceae, 7 Cyanophyceae and 3 to Chlorophyceae. The highest phytoplankton production was observed in November (578.0 x 105 cells/L) and the lowest in June (37.5 x 105 cells/L). Some hydrographic parameters e.g., surface water temperature, salinity and nutrients (N03-N and P04-P) were recorded and their relationship with the occurrence and abundance of phytoplankton population were also studied. Nutrient concentration was higher during the autumn months, when rain water provided the maximum outflow of rivers discharging into the channel. During the nutrient peak period, the total phytoplankton production was maximum. Bacillariophyceae was the dominant group of phytoplankton throughout the study period except in June and September, when Dinophyceae was dominant. Cyanophyceae was abundant in spring months when temperature began to rise.

Occurrence of Zoothamnium sp. infection in Penaeus monodon (Fabricius, 1798) of the coastal shrimp culture ponds of Cox's Bazar Bangladesh

Penaeus monodon (Fabricius, 1798) is a popular cultivable species and valuable foreign exchange earning item among all the fishery commodities in Bangladesh. At present with semi-intensive and intensive shrimp culture practices, disease is a problem. Protozoan infection, caused by the Zoothamnium sp. is one of the causes of damage in the total production by growth retardation and mortality. No work has yet been done on shrimp disease in Bangladesh. The present account therefore, constitutes the first report on it from the shrimp culture ponds of Cox's Bazar. The present work includes the occurrence and prevalence of protozoan disease, its seasonal variations and level of infestation in different length groups in Penaeus monodon.

Classification using log Gaussian Cox processes

McCullagh and Yang (2006) suggest a family of classification algorithms based on Cox processes. We further investigate the log Gaussian variant which has a number of appealing properties. Conditioned on the covariates, the distribution over labels is given by a type of conditional Markov random field. In the supervised case, computation of the predictive probability of a single test point scales linearly with the number of training points and the multiclass generalization is straightforward. We show new links between the supervised method and classical nonparametric methods. We give a detailed analysis of the pairwise graph representable Markov random field, which we use to extend the model to semi-supervised learning problems, and propose an inference method based on graph min-cuts. We give the first experimental analysis on supervised and semi-supervised datasets and show good empirical performance.

The effects of CpG-C oligodeoxynucleotides on innate immune responses in Eriocheir sinensis (H. Milne-Edwards, 1853)

CpG oligodeoxynucleotides (ODNs) can stimulate the immune system, and therefore are widely used as a therapeutic vaccination and immune adjuvant in human. In the present study, CpG-C, a combination of A- and B-class ODN, was injected into Chinese mitten crab Eriocheir sinensis at three doses (0.1, 1 and 10 mu g crab-1), and the reactive oxygen species (ROS) levels, activities of total intracellular phenoloxidase (PO) and lysozyme-like activities, the mRNA transcripts of EsproPO, EsCrustin and EsALF were assayed to evaluate its modulating effects on the immune system of crab. The ROS levels in all treated and control groups were significantly increased from 6 to 24 h, except that ROS in 0.1 mu g CpG-C-treated crabs was comparable to that of the blank at 6 h. The PO activity was significantly enhanced and EsproPO transcripts were down-regulated (P < 0.01) at 6 h after the injection of 0.1 mu g CpG-C, with no significant changes in the other dosage treatments. The lysozyme-like activities and EsCrustin transcripts in the CpG-C-treatment groups were significantly higher than those of controls. The mRNA expression of EsALF remained almost constant in all the groups during the treatment. These results collectively suggested that CpG-C could activate the immune responses of E. sinensis, and might be used as a novel immunostimulant for disease control in crabs.
