Temporal pattern of fish production in a microtidal tropical estuary in the south-west coast of India

The status of fisheries and seasonal variation in fish diversity in the Kodungallur-Azhikode Estuary (KAE) were investigated. Total annual average fish production in the estuary declined significantly to 908.6 t with average yield of 5.4 kg ha-1 day-1, when compared to earlier study; where 2747 t was reported. During the present study, 60 species of finfishes (belonging to 34 finfish families), 6 species of penaeid shrimps, 2 species of palaemonid prawns, 2 species of crabs (4 crustacean families), 6 species of bivalves and 2 species of edible oysters (3 molluscan families) were noticed. Finfishes were the major group that contributed 69.62% of total fishery in the estuary and crustaceans (23.47%), bivalves (6.84%) and oysters (0.07%) also formed good fishery. Many of the fish species in the estuary were observed as threatened (Horabagrus brachysoma, Channa striatus, Channa marulius, Clarias batrachus, Heteropneustes fossilis and Wallago attu). The major fishing gears employed in the estuary were gillnets, cast nets, stake nets, scoop nets, ring nets, traps and Chinese dip nets. Gillnets contributed 45% of the total fish catch. Gillnets also showed highest catch per unit effort (CPUE) of 6.91 kg h -1 followed by cast nets (1.85 kg h -1), Chinese dip nets (3.20 kg h -1), stake nets (3.05 kg h -1), ring nets (1.27 kg h -1), hooks and lines (1.35 kg h -1) and scoop nets (0.92 kg h -1). The study implies that temporal changes in fish landing pattern of the KAE was mainly due to environmental variability, habitat modification and fish migration; under the influence of south-west monsoon and anthropogenic activities in the KAE. Results of the study suggest that spatio-temporal variations in the fish community structure could be an indicator for anthropogenic stress and it should be considered for restoration programmes.

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

Plan exportador para la empresa DAGALA plásticos E.U

La internacionalización es un paso muy importante para las empresas que desean alcanzar mercados exteriores e incrementar ventas asegurando la sostenibilidad en el tiempo. La globalización viene siendo un tema crucial no solo para las naciones sino también para las empresas. Mientras que los gobiernos deben preocuparse por establecer políticas que los haga competitivos frente al mundo, las empresas, estando en ese lecho de políticas deben generar estrategias que garantice su perdurabilidad en los mercados. Por otro lado las empresas deben ser conscientes que las necesidades se transforman y en cuanto esto pase, las organizaciones deben tener la capacidad de respuesta oportuna para satisfacer lo que la demanda requiera, pues los consumidores de hoy, son altamente exigentes y difícilmente fieles. Las empresas que desean internacionalizarse deben ser estrategas para realizar los pasos adecuados tomando las decisiones más acertadas, por lo que esta investigación busca basarse en fuentes bibliográficas y guías en expertos para consolidar la información y traducirla en el diseño del plan exportador que busque reducir riesgos. DAGALA Plásticos E.U es la empresa en la cual esta investigación se va a basar, dicha organización es una pyme colombiana que se dedica a la producción de ganchos plásticos de excelente calidad con material reciclado (polipropileno). Por ende es una empresa que pertenece al sector de los plásticos, pero se enfoca a un nicho de mercado mucho más popular pues el producto que ofrecen es de bajo precio debido al material que usan. Su clasificación internacional industrial uniforme es 2529 que hace referencia a la fabricación de artículos de plástico, este código está acorde con el International Standard of Industrial Classification of All Economic Activities (ISIC) el cual es el código internacional desarrollado por UN como una manera estándar para la calificación de las actividades económicas. Se busca diseñar el plan exportador para dicha empresa, dividiendo el estudio en etapas. En la primera se pretende realizar un diagnóstico situacional con el fin de saber cómo está la empresa actualmente lo cual nos resolverá su potencial para exportar dado en fortalezas y debilidades. Si la primera etapa arroja resultados satisfactorios, el siguiente paso es realizar un estudio de mercado para encontrar el país más propicio a exportar, con un análisis debido de competencia y de barreras al comercio. Por el contrario, si no arrojan resultados positivos, se enfocará en las debilidades para hacer más posible en un futuro la exportación. La tercera etapa se concentrará en formular la logística del producto desde su punto de fabricación hasta el país final. Y finalmente se concluirá el trabajo.

Chaucer's presence in songes and sonettes

In an elegy to Wyatt published in Tottel’s Miscellany, Surrey claims that Wyatt ‘reft Chaucer the glory of his wit’. This statement, which both lauds and resists Chaucer, is a microcosm of the way Chaucer is treated throughout the Miscellany. In examining the collection’s paradoxical attitude to Chaucer, this essay focuses particularly on the Squire’s Tale, the Franklin’s Tale, Anelida and Arcite, the Legend of Good Women, and several short lyrics. In its interest in courtly love poetry and Petrarch, the Miscellany follows a trajectory in English poetry set by Chaucer. Its courtly verse is saturated with words, phrases, and tropes from his poetry. Rhyme royal, which he introduced into English poetry, is widely used. The Canterbury Tales has been fully assimilated and can be referred to allusively with the same confidence of the audience’s knowledge as is the case when referring to classical myth; in Wyatt’s ‘Myne owne Jhon Poins’, the speaker, disclaiming deceitfulness, says that he cannot ‘say that Pan/ Passeth Appollo in musike manifold:/ Praise syr Topas for a noble tale,/ And scorne the story that the knight tolde’ (lines 48-50). However, Chaucer’s poetry is also downplayed and contested in the Miscellany. ‘Truth’, the only poem of his which appears in the volume, is disingenuously placed in the ‘Uncertain Authors’ section. In addition, some of the most important elements of his work are strongly resisted in the Miscellany, either ignored, dismissed or challenged. These elements include Chaucer’s interest in variety of voice, his sympathetic engagement with women, particularly wronged women, and his interest in female speech and particularly female complaint. The Miscellany, by contrast, is dominated by male-voiced lyrics preoccupied with the pain inflicted on the lover by a lady who is frequently unfeeling, cruel, or faithless. Chaucer’s frequent focus on the cynical seduction and betrayal of female by male is reversed in the Miscellany, and the language and metaphors he uses to express male cruelty (e.g. the word ‘newfangleness’ and images of hooks, nets and traps) are usurped to describe the lady’s cruelty to the suffering lover. On occasion, poems in the Miscellany challenge specific Chaucerian texts; ‘On His Love Named White’ throws down a gauntlet to The Book of the Duchess, while two of Surrey’s poems implicitly take issue with the female falcon’s voice in the Squire’s Tale, giving the deceitful tercelet the opportunity to shout down the falcon’s charges. The essay thus shows that in many respects Tottel’s Miscellany is only superficially Chaucerian, and that it both passively and actively takes issue with Chaucer’s work.

Exploring identities and cultures in inter-professional education and collaborative professional practice

Although the concept of multi-agency working has been pursued and adopted as the most appropriate way to improve child care provision and health workforces in recent years, both in the UK and more globally, research suggests that participation in such work can be problematic. This article examines current developments in inter-professional education and collaborative professional practice. Drawing on desk research across the fields of Education, Health and Social Care, it applies a critical lens to re-examine inter-professional working using well-established concepts of profession, identity, culture, career, and training/work transitions. The article uses theoretical hooks to look for similarities and differences in the promotion of inter-professionality across the Education, Health and Social Care sectors, alongside those which occur within each. It looks towards a re-invigoration of knowledge creation and application through research. This is viewed as especially urgent in times of fragmentation, transformation, and arguably, disintegration, in the services its professional and academic educators and workers seek to serve.

A new species of Moenkhausia from the rio Amazonas and rio Orinoco basins (Characiformes: Characidae)

A new species of Moenkhausia is described from the rio Amazonas and rio Orinoco basins. The new species can be distinguished from congeners mainly by the combination of a conspicuous, relatively small and circular humeral spot, a black spot on the upper caudal-fin lobe, lower caudal-fin lobe without spot or a faint one, and middle caudal-fin rays hyaline or with dark tips. Mature males have a unique combination of two large-sized bony hooks on the anal-fin rays and tiny spines on the distal portion of all fins, which distinguishes the new species from any other species of Characidae.

What Bronx Community College Students Can Do!

The dominant discourse in faculty spaces with respect to student performance too often focuses on what community college students, in need of developmental courses, can’t do. Deeply inspired by the work of Robert Glaser, Lev Vygotsky, bell hooks, and Bagele Chilisa we (Monique Guishard, and four intermediate psychology students) have collaborated using student podcasts to theorize back to deficit, damaged centered theories of student underperformance.

Ecologia reprodutiva do peixe-donzela, Stegastes fuscus cuvier, 1830 (osteichthyes: pomacentridae) em arrecifes rochosos da praia de Búzios, Rio Grande do Norte, Brasil

The reproductive ecology of fish plays a key role both for rational exploitation methods and for protective measures of natural stocks. The purpose of this study was to analyze the reproductive aspects of the damsel-fish, Stegastes fuscus, during October 2004 to September 2005, in the coastal rocky reefs of Búzios Beach, Nísia Floresta, RN. Fish were captured using hooks and hand nets, during low tide. Reproduction was determined using sexual ratio, mean length of first maturation (L50), absolute fecundity and macroscopic characteristics of gonads. The following parameters were related to gonadosomatic index (GSI): condition factor (CF), hepatosomatic index (HSI), rain fall and temperature. In relation to sex distribution, it was observed that 78% were females and 22% were males. The L50 was 6.2 cm for females and 7.0 for males. Average fecundity was 6832 oocytes. Results showed that S. fuscus had better body condition in the months prior to spawning, particularly during initial and intermediate stages of maturation. Five stages of gonadal maturation were identified through macroscopic analysis: immature, in maturation, mature, spent and resting. The HSI was inversely related to the GSI. This was possibly due to the reproductive cycle of this species which was associated to the dry period of this region. During this period, low rain fall and high temperatures provide an propitious reproductive condition for the study species

Caracterização da captura incidental de tartarugas marinhas pela pesca de espinhel pelágico no Nordeste do Brasil

The marine turtles biological characteristics and the impact they have been suffering in consequence of human activities have caused in the last decades the decrease of populations to unsustainable levels. All four of the species described in this paper are registered as endangered in a list by IUCN: Caretta caretta, Lepidochelys olivacea, Chelonia mydas, Dermochelys coriacea. The main causes of such impact include several fishing activities, mostly the surface longline. This paper discusses the monitoring of two foreigner longline fleet along the North East Brazilian coast between October of 2004 and September of 2005. Both operated in the West South Atlantic, one using the Chinese technique and the other the American. The American method s target species is the swordfish (Xiphias gladius), and it is characterized by using squid as bait, J 9/0 offset 5º hook, light sticks and night soaking. It also operates in shallower waters than the Chinese method. The source of information about the efforts and the catches came from onboard observers and were used to calculate the catching rate of turtles over 1000 hooks (CPUE). The American equipment caught more turtles (CPUE = 0,059; N= 103), mainly D. coriacea, while the Chinese longline caught mainly the L. olivacea and presented a CPUE= 0,018 (N= 89). The hooks were most frequently found attached to the mouth of C. caretta, C. mydas, and L. olivacea. The D. coriacea were most frequently caught by hooks externally attached to different parts of their body. There was no significant difference between the hook type catching and most turtles were still alive when released. The results suggest a greater potential of turtle catching by the American method. Besides the statistic tests have showed less interaction between the Chinese equipment and marine turtles, the catches of this fishing technique could have been underestimated due to miscommunication between the onboard observer and the vessel s crew plus the retrieve of the longline during night time

Recent Studies on Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae), in Prochilodus lineatus Valenciennes, 1836, from Volta Grande Reservoir, MG, Brazil

O presente trabalho estudou a helmintofauna do curimbatá, Prochilodus lineatus Valenciennes, 1836, do reservatório de Volta Grande, MG, Brasil. Foram analisados 18 peixes com comprimento médio de 46,7 ± 1,1 cm e peso médio de 1.674,8 ± 75,6 g, sendo que 15 apresentaram acantocéfalos no intestino com prevalência de 83,3%. O helminto foi identificado como Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae), que diferiu das outras espécies descritas pelas dimensões dos caracteres e pela morfologia. da descrição original de N. curemai difere pelas maiores dimensões dos testículos, pela glândula de cimento alongada, pela presença de núcleos nos lemniscos, pelas dimensões dos ovos e pelos maiores ganchos da probóscide presentes na segunda e na terceira fileiras nos machos e na primeira fileira nas fêmeas. Foi observada menor porcentagem ocupada pelo sistema reprodutivo em relação ao tronco da fêmea. A observação dos parátipos de N. curemai de Noronha (1973) mostrou grande semelhança com os do presente trabalho. Este fato complementa a descrição do helminto em outra localidade.

Stand-alone posterior ressection of lumbar hemivertebrae: case report

Background: In this case report we presented the stand-alone posterior approach for hemivertebra resection with unilateral laminar hooks.Case report: The patient was male and five years old. The coronal and sagital X-Rays images showed a failure of vertebral formation, segmented hemivertebra of third lumbar vertebra. The segmented hemivertebra caused a thoracolumbar scoliosis from T12 to L4 (rightside convexity), of 30 degrees (Cobb angle). The patient was submitted to a hemivertebra resection from posterior approach with two unilateral laminars hooks stabilization (superior lamina in L2 and inferior lamina of L4) in association to a compression system and autologus bone graft. The coronal X-Ray image after surgery showed a partial improvement to 25 degrees (Cobb angle) between L2 and L4. After three years of follow up it was not observed system failure (hook pull-out), maintance of curve (25 degrees of Cobb angle) and correction of trunk inbalance.Conclusion: The hemivertebra resection with posterior approach is safe, with satisfactory correction of scoliosis curve, which means is a good choice for congenital scoliosis surgical treatment.

Endovascular Treatment of Late Aortic Perforation due to Vena Cava Filter

Perforation of inferior vena cava (IVC) by filter struts ranges from 9% to 24%, and clinical sequelae and complications are unpredictable. The aim of this article was to report an unusual case of late complication of IVC filter that caused an IVC wall perforation and penetration of the filter's hooks in the aorta, which was treated by endovascular procedure. Molding strut tip by balloon angioplasty, its accommodation with a bare stent, and its coverage and protection with an endoprosthesis is probably the first technique reported so far in this situation.
