Behaviour of REEs in a tropical estuary and adjacent continental shelf of southwest coast of India: Evidence from anomalies

The distribution and accumulation of the rare earth elements (REE) in the sediments of the Cochin Estuary and adjacent continental shelf were investigated. The rare earth elements like La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and the heavy metals like Mg, V, Cr, Mn, Fe, Cu, Zn, U, Th were analysed by using standard analytical methods. The Post-Archean Australian Shale composition was used to normalise the rare earth elements. It was found that the sediments were more enriched with the lighter rare earth elements than the heavier ones. The positive correlation between the concentrations of REE, Fe and Mn could explain the precipitation of oxyhydroxides in the study area. The factor analysis and correlation analysis suggest common sources of origin for the REEs. From the Ce-anomalies calculated, it was found that an oxic environment predominates in all stations except the station No. 2. The Eu-anomaly gave an idea that the origin of REEs may be from the feldspar. The parameters like total organic carbon, U/Th ratio, authigenic U, Cu/Zn, V/Cr ratios revealed the oxic environment and thus the depositional behaviour of REEs in the region

Algal Blooms and Associated Bacteria along the Southwest Coast of India

It is essential to understand how the distribution and composition of microalgae as well as dynamics of HABs in economically important shelf seas relate to the particular physico-chemical and biological properties of the water column in which they live. In view of the importance of southwest coast of India, which is considered as one of the most biologically productive areas in the world, regular monitoring of distribution and abundance of microalgae is important. The present work is concentrated on the estuarine and coastal open sea stations along the southwest coast of India. In order to get further insights into the abiotic factors governing bloom dynamics, the physicochemical parameters that regulated three particular bloom events during this period were studied. Bearing in mind the role of bacterial fauna associated with algal blooms as a biological factor in regulating its dynamics, isolation of bacteria associated with the algal blooms, their identification, enumeration, and ability to produce extracellular enzymes have been duly incorporated into this study

Fishery and biology of deep-sea chondrichthyans off the southwest coast of india

Elasmobranchs comprising sharks, skates and rays have traditionally formed an important fishery along the Indian coast. Since 2000, Indian shark fishermen are shifting their fishing operations to deeper/oceanic waters by conducting multi-day fishing trips, which has resulted in considerable changes in the species composition of the landings vis- a-vis those reported during the 1980’s and 1990’s. A case study at Cochin Fisheries Harbour (CFH), southwest coast of India during 2008-09 indicated that besides the existing gillnet–cum- hooks & line and longline fishery for sharks, a targeted fishery at depths >300-1000 m for gulper sharks (Centrophorus spp.) has emerged. In 2008, the chondrichthyan landings (excluding batoids) were mainly constituted by offshore and deep-sea species such as Alopias superciliosus (24.2%), Carcharhinus limbatus (21.1%), Echinorhinus brucus (8.2%), Galeocerdo cuvier (5.4%), Centrophorus spp. (7.3%) and Neoharriotta pinnata (4.2%) while the contribution by the coastal species such as Sphyrna lewini (14.8%), Carcharhinus sorrah (1.4%) and other Carcharhinus spp. has reduced. Several deep-sea sharks previously not recorded in the landings at Cochin were also observed during 2008-09. It includes Hexanchus griseus, Deania profundorum, Zameus squamulosus and Pygmy false catshark (undescribed) which have been reported for the first time from Indian waters. Life history characteristics of the major fished species are discussed in relation to the fishery and its possible impacts on the resource

Deep-sea shrimp fishery off Kerala coast with emphasis on biology and population characteristics of Plesionika quasigrandis Chace, 1985

The present study is the first attempt to understand population characteristics of the deep-sea pandalid shrimp, P. quasigrandis and to assess the status of these resources off Kerala coast.Total mortality coefficient (Z) of P. quasigrandis estimated by various methods.Natural mortality coefficient (M) calculated was 0.65 and 1.02 by Pauly‟sempirical formula and Srinaths‟s formula respectively The deep-sea shrimp P. quasigrandis exploited from the present fishing ground and their monetary return has started showing a declining trend. By observing the current yield and economic return, there is no further scope for increasing the catch from the present fishing ground. The study indicated that majority of the deep-sea shrimp trawlers, especially targeted for pandalid shrimps still concentrated off Kollam area (Quilon Bank). Even though researchers had located several potential deep-sea fishing grounds based on exploratory surveys in Indian EEZ , fishermen are unaware of these fishing grounds located and hence sharing the information about new potential deep-sea fishing grounds could avert the possible stock decline due to the intensive targeted deep-sea shrimp fishery in the Quilon Bank. Hence, the present study recommended that part of the effort from existing fishing grounds may be shifted to newly located deep-sea fishing grounds which will help in a sustainableexploitation of deep-sea resources off Kerala coast.

Population characteristics and taxonomy of lantern fishes of genus Diaphus (Family Myctophidae) off south west coast of India

Globally most of the conventional fish stocks have reached a state of optimum exploitation or even over-exploitation; efficient utilization of non-conventional resources is necessary to meet the supply-demand gap for protein supply. Mesopelagic fishes can be considered as one such promising resource for the future, if appropriate harvest and post-harvest technologies are developed. Increasing human population and increasing demand for cheaper food fishes has made myctophids a possible potential resource for future exploitation and utilization. Earlier studies indicated the abundance of Diaphus spp. in the eastern and northeastern Arabian Sea. The present study also indicates the dominance of Diaphus spp. in the deep sea trawling grounds of south west coast of India. Commercial viability of the myctophid fishing in the Indian waters has to be worked out. The present catch estimation is based on the Stratified Random Sampling Method from the landing data. As the coverage of sampling area was limited and the gear efficiency was not standardized, the data generated are not precise. A counter check for the estimates is also not possible due to the absence of comparable works in the study area. Fish biomass estimation by acoustics survey coupled with direct fishing would only confirm the accuracy of estimates. Exploratory surveys for new fishing areas to be continued, for gathering the distribution, abundance, biological and ecological data and map the potential fishing ground on a GIS platform and the data should be provided to the commercial entrepreneurs. Generally non-conventional and non-targeted resources are under low fishing pressure and exploitation rates. Low values of fishing mortality and exploitation rates indicate that removal from the stock by fishing was only nominal from the present fishing grounds. The results indicate that the stock is almost at virgin state and remains grossly underexploited. Since the extent of distribution and abundance of the stock in the ecosystem remains to be ascertained, sustainable yield could not be estimated. Also the impact of myctophids harvest, on other commercially important fishes, has to be studied.

Plan Exportador para Improquisa S.A. de tapas poly guard en el mercado latinoamericano 2011-2012

A través del uso de distintas metodologías para la elaboración de un plan exportador, y con la ayuda y guía de nuestro director Andrés Castro, se ha elaborado un análisis integral que le permitirá a la empresa Improquisa S.A., tener algunos elementos clave a su disposición en el momento en que deseen aprobar su plan de exportación o elaborar uno propio. Se inicia entonces con un análisis del sector de plásticos en Colombia, identificando las empresas que hacen parte del sector y que se destacan por tener ingresos operacionales por encima del nivel de las otras empresas. Así se encuentra que hay pocas empresas en pocos lugares de Colombia que conservan estas características. De la misma manera se identifican cuales son las empresas que exportan y hacia que destinos en años anteriores. Luego, pasamos a observar la empresa en su totalidad, pasando desde un planteamiento de su estrategia competitiva hasta un análisis financiero, pasando por todas las áreas de la empresa puesto que una exportación, al ser una actividad integral, involucra a la empresa en su totalidad y por esto se debía analizar completamente. El siguiente paso es entonces decidir a qué mercado exportar y las razones por las cuales se le da prioridad a ese destino por encima de los demás. Dicho ejercicio es realizado con la metodología de Andrés Castro en la que se toman tres potenciales mercados y, a través de la calificación y análisis de variables, se identifica cuál se adapta mejor a las necesidades y capacidades de la empresa. Finalmente se identifican clientes potenciales en el mercado objetivo y se mencionan estrategias claves que pueden ser utilizadas por la empresa para la consecución del plan exportador. Esperamos entonces que este ejercicio sea de gran utilidad para la empresa Improquisa S.A.

Exemplo de empreendedorismo no ensino de Turismo : trabalho realizado por uma aluna do Mestrado na cadeira de Empreendedorismo e Liderança da Universidade Lusófona ; Albergue Hostel em Peniche ''West Coast Hostel''

No âmbito da cadeira de Empreendedorismo e Liderança, leccionada no Mestrado de Turismo da Universidade Lusófona, o trabalho final consiste em cada aluno apresentar um exemplo prático de sua iniciativa, no lançamento de um projceto turístico, de acordo com os objectivos e conteúdos programáticos da cadeira. Como refere o Prof. Abranja no seu artigo, “os pequenos empreendimentos que transitam do sonho para o mercado são fundamentais para o desenvolvimento económico e social de qualquer região.” Poderia seleccionar outros trabalhos, mas este tem todos os ingredientes de ser um exemplo para todos quanto queiram ser empreendedores e tomar a sua paixão realidade. O facto desta proposta de empreendedorismo ser localizada fora da Grande Lisboa, reafirma a vocação do Ensino Superior de Turismo em ter uma dimensão nacional, adequada ao espírito lusófono que se pretende incutir nos alunos. Outra razão desta escolha, é a de ser um projecto de pequena dimensão, na sua fase inicial e acessível para que os seus sonhos e paixões, factores essenciais para que um projecto de empreendedorismo tenha bases sustentadas para alcançar o êxito empresarial.
