Auxiliary Source

The state of Maranhão has a vast coastline that promotes the development of coastal recreational fishery, an activity that has attracted more and more fans in recent years. In this context, the objective of this work was to demonstrate the importance of sport fishing as an auxiliary source in monitoring the diversity of fish on the beaches of the metropolitan region of São Luís, Maranhão, through the monitoring of sport fishing tournaments, held in December 2018 on the beach do Olho d‟água and in July 2019, at Araçagi beach. The captured fish were stored in isothermal boxes containing ice and transported to the laboratory for taxonomic identification. 252 specimens were captured, belonging to 19 species, and distributed in 10 families. The family Sciaenidae was the most representative with 3 species. The predominant species were Conodon nobilis and Genyatremus luteus from the Haemulidae family, which together represented 39% of the specimens captured on the Olho d‟água beach and 24% on the Araçagi beach. The individuals of C. nobilis had an average weight of 29.4 ± 12.7 g and an average length of 12.3 ± 2.0 cm, with a curve of weight x length ratio represented by the equation PT = 0.034 CT2.6637 and R2 = 0, 67, with b = 2.67. While in G. luteus, the individuals had an average weight of 96.5 ± 82.2 g and an average length of 15.8 ± 4.4 cm, with a curve of the weight x length ratio represented by the equation: PT = 0.0145CT3.0999 and R2 = 0.81, with b = 3.09. The diversity of fish in beach fisheries can contribute to studies of fishery biology to support the development of management strategies and conservation of fish stocks.

Biological Performance

This experiment was carried out in order to know the variation of the morphometric relation between the length and the width of the shell of abalone Haliotis tuberculata as well as the evolution of the factor of condition.Haliotis tuberculata used in the study is a gastropod that belongs to the order Vetigastropoda, and the family Haliotidae. 135 abalones with an average weight of 5.55±1.24 g, an average length and shell width of 3.14±0.23 cm and 2.12±0.18 cm were selected for the experiment.These individuals were divided into three different densities (10, 15, 20 individuals) in nine (9) plastic tanks with a base area of 0.15 m2 of 3 tanks per density. The abalones from each tank were fed 70% of their body weight with available macroalgae such as Ulva lactuca and Dictiopeterus sp. Morphometric relationships that include the relationships between length-width and condition factor were determinedAt the end of 12 months of experimentation, changes in length, width, and annual average weight as a function of density indicate that low stocking densities favor a faster increase in these variables (length, width, and weight). The analysis of these relationships indicates a strong correlation between the length and width of the Haliotis tuberculata shell. However, it is noted the correlation between these two variables decreases inversely with density. The average values of the condition factor are 18.89 ± 0.96, 18.72 ± 1.18 and 18.59 ± 1.14 for densities D10, D15 and D20 respectively. Analysis of the results of this study shows that when population density becomes too high, the growth of H. tuberculata is slowed down both in weight and in size. The condition factor analysis also indicates that the best biological performance is obtained at the lowest density (D10) thus inducing better growth.

Selama keluarga mendampingi perawatan pasien di ruang ICCU, keluarga akan mengalami berbagai reaksi emosional seperti kecemasan. Tujuan: Mengetahui hubungan lama hari rawat dengan tingkat kecemasan keluarga pasien di ruang ICCU. Metode: Korelasi dengan pendekatan cross sectional dengan sampel 42 responden di ruang ICCU, yang dipilih dengan menggunakan metode purposive sampling. Instrumen penelitian ini menggunakan kuesioner HARS.  Data dianalisis dengan uji korelasi Spearman. Hasil: Lama hari rawat pasien rata-rata 3,14 hari.  Kecemasan keluarga pasien ICCU paling banyak berada pada tingkat kecemasan berat (33,3%). Terdapat hubungan yang bermakna antara lama hari rawat dengan tingkat kecemasan keluarga pasien (p=0,0003) dengan keeratan hubungan yang sedang (r=0,532) di ruang ICCU. Diskusi: Semakin lama pasien dirawat di ruang ICCU maka semakin tinggi tingkat kecemasan yang dirasakan keluarga pasien karena kondisi pasien yang tidak stabil ataupun semakin parah. Kesimpulan: Keluarga pasien perlu diberikan informasi dan edukasi yang jelas terkait kondisi pasien dalam sehari atau saat ada perburukan kondisi.Kata kunci: kecemasan, keluarga, lama hari rawat, perawatan intensif, perawatan kritis. Correlation Between Length of Stay and Anxiety Levels of Patients’ Family in Intensive Cardiac Care Unit Room ABSTRACTWhile a patient is being treated in the Intensive Cardiac Care Unit (ICCU), the patient's family experiences difficulties and helplessness. For the patient's family, the intensive care unit is an unpleasant place. The family enters into unexpected conditions and is required to make proper decisions for survival related to patient conditions. The patient's length of stay in the ICCU room is very diverse. The length of stay of ICCU patients directly impacts patients' quality of life and their families, the risk of future incidence, and the extent of the treatment cost. While the family accompanies the patient treated in the ICCU room, the family will experience various emotional reactions such as anxiety. Objective: To reveal the correlation between length of stay and the anxiety levels of the patient’s family in the ICCU room. Methods: Correlation with cross-sectional approach with a sample of 42 respondents in the ICCU room, who were selected using a purposive sampling method. The research instrument used the HARS questionnaire. Data were analyzed using the Spearman correlation test. Results: The average length of the patient's stay was 3.14 days. Family anxiety of ICCU patients was mostly at the level of severe anxiety (33.3%). There was a significant correlation between length of stay and anxiety levels of the patient’s family (p=0.0003) with a moderate correlation coefficient (r=0.532) in the ICCU room. Discussion: The longer the patient is treated in the ICCU room, the higher the anxiety level felt by the patient’s family due to the patient's unstable or worsened condition. Conclusion: Clear information and education should be given to the patient's family regarding the patient's condition within one day or when the condition worsens.Keywords: anxiety, family, length of stay, intensive care, critical care

This paper describes and discusses the impacts of the passage of cold fronts on the vertical structure of the Carlos Botelho (Lobo-Broa) Reservoir as demonstrated by changes in physical, chemical, and biological variables. The data were obtained with a continuous system measuring 9 variables in vertical profiles in the deepest point of the reservoir (12 m) coupled with climatological information and satellite images, during a 32-day period in July and August, 2003. During periods of incidence of cold fronts the reservoir presented vertical mixing. After the dissipation of the cold fronts a period of stability followed with thermal, chemical, and biological (chlorophyll-a) stratification. Climatological data obtained during the cold front passage showed lower air temperature, higher wind speed and lower solar radiation. The response of this reservoir can exemplify a generalized process in all shallow reservoirs in the Southeast Brazil and could have several implications for management, particularly in relation to the phytoplankton population dynamics and development of cyanobacterial blooms. Using this as a basis, a predictive model will be developed with the aim of advancing management strategies specially for the drinking water reservoirs of the Metropolitan Region of São Paulo.

Background: Children with severe acute malnutrition (SAM) having medical complications require immediate care at malnutrition treatment centers (MTC). Thus, it becomes important to assess the effect and treatment cost of such children in these facilities. Hence, the present study was done with these aims in two MTCs in Jharkhand, India.Methods: A retrospective record review was done of the children admitted to these two MTCs between 1st April 2017 and 31st March 2018. A predesigned proforma was used to collect child related information. The data collected was entered in Microsoft excel sheet and analysed.Results: Majority of the admitted children (90.6%) were in 6-23 months age group. 358 (51.5%) children were females. Only, 194 (27.9%) children admitted were SAM had any medical complication. 690 (99.3%) children were discharged of whom 499 (72.3%) were discharged after achieving the target weight. The average weight gain during their stay was 8.1±2.4 g/kg/day and average length of stay was 16.7±3.2 days. Post discharge follow up rates were found to be low and only 130 (18.8%) children completed all three follow ups. Average cost per SAM child treated was Rs. 18,599 (US$ 272) and per SAM child cured was Rs. 25,904 (US$ 379).Conclusions: MTCs are effective in managing medically complicated SAM children. However, improvements are necessary to ensure that more such children should be treated at facility level, complimented with a community based programme for managing uncomplicated SAM children to improve coverage and ensure continuum of care.

<p>Globally, commercially exploited fish species are coming under more and more pressure as the population of humans grow. Protein from the sea has traditionally been available to coastal communities throughout history. In modern times however, traditional artisanal fisheries have been replaced by commercial fishing industries. It is estimated by some authorities that these modern fisheries have led to decreases in pre-exploitation biomass of desirable species of up to 90%. As desirable species decline, secondary species become more valuable and subject to exploitation. An issue with this exploitation is that management decisions of fish stocks are often based on political or commercial concerns rather than sound science focussed on preserving stocks, and ultimately, fishing industries. To investigate phylogenetic and phylogeographic relationships of fish, kahawai (Arripis trutta) was used as a proxy species. A. trutta is one of only four members of the genus Arripis, which in turn is the sole member of the family Arripidae. It was found that a single, highly connected population of A. trutta inhabit New Zealand waters, and approximately 15 migrants per generation make the journey between New Zealand and Australia, genetically linking these populations. A phylogeny of A. trutta was resolved using mitochondrial DNA, and while COX1 data supported the hypothesis that A. trutta forms a monophyletic clade within the Stromateoids (medusa fish, squaretails and drift fish) and the Scombrids (tuna, mackerel and their allies) suggesting a common ancestor, other data collected during the investigation does not support this hypothesis.</p>

Sport fishing is one of the fastest growing leisure categories in today's world. In Brazil it is also practiced as a sport or leisure, noncommercial purposes. However, few studies are conducted in order to manage this activity in a sustainable manner. This study aimed to analyze sport fishing, practiced the "Fisherman’s Deck" (Santos, SP, Brazil), describing their biological characteristics and the socioeconomic profile of its participants. We interviewed 150 fishermen, aged between 12 and 82 years, 85% male. The majority (56%) has a college degree and resides near the fishing spot. The target species are swordfish (Trichiurus lepturus), bass (Centropomus spp.), Hake (Cynoscion spp.), betara (Menticirrhus americanus), corvina (Micropogonias furnieri) and hake-yellow (Macrodon atricauda). Three types of fishing, bottom fishing, surface and crab were identified. Fishermen indicated that fish stocks have declined due to increased commercial fishing and pollution. Each fishery lasted on average 5.0 (S.D.=2.1) hours and captured 850,8g (S.D.=962.5) g / angler / day. The estimated catch for the study period was 1314.8 (S.D.=1919.1) kg, representing less than 3% of fish landed by commercial fishing. Therefore, sport fishing from "Fisherman’s Deck" causes low impact to regional fish stocks.

Preliminary Study

Matrinxã is a very promising amazonian fish for fish culture in Brazil. This study is aimed at determining the approximate tolerated temperature range in this species. Groups of ten young matrinxã specimens (15.1±0.8 cm average length and 58.3±10.3 g average weight) were subjected to 9 different temperatures for 24 hours without previous acclimation. Fish were transferred from an initial temperature of 27ºC to those ranging from 12 to 39ºC at 3ºC intervals. Both 12ºC and 39ºC temperatures were lethal for this species with 100% mortality rate. Following 2 minutes of exposure to 39ºC fish changed behavior, showing an increase in opercular movements and erratic swimming; mortality reached 100% after 18 minutes. At 12ºC, fish lost equilibrium immediately after exposure and started swimming erratically; after only 4 minutes fish became lethargic and remained immobile on the bottom of the tank. Total mortality was only evident following 24 hours. At 15ºC matrinxã lost equilibrium after 5 to 6 minutes of exposure but mortality was only 20% after 24 hours. Fish tolerated well temperatures ranging from 18 to 36ºC with 100% survival after 24 hours. This preliminary study suggests that temperatures between 18 and 36ºC are the approximate range normally tolerated by this species, although survival at other temperatures may be increased by gradually acclimating fish to the more severe increases or decreases in temperature. In addition, it indicates that matrinxã may be cultivated over a wide geographical area.

The Emas waterfall in Mogi-Guaçu River is regionally recognized as an important fishing spot and touristic place. The first reports of the professional and sport fishing there date back from the 30's, which is the same period when the tourism took place. The present paper provides an environmental valuation of this place and an assessment of the differences among the major groups of people using the area. During 2006 we interviewed 33 professional fishers, 107 sport fishers, 45 tourists and 103 excursionists in order to estimate the Willingness to Pay (WTP) for each category and to analyze the influence of socioeconomic factors by means of logistic regressions and ANCOVAs. The WTP of professional fisher was significantly influenced by age and education, and the WTP for the sport fishers was influenced by the family income. The variables that influenced the tourists' and excursionists' WTP were sex and education. The total annual aggregated value to maintain the waterfall in the current conditions was estimated in US$ 11.432.128, and US$ 55.424.283 to restore it.

AbstractIn this study karyotypic features of the five species of the family Bufonidae from the central area of Argentina are described. The species are Rhinella achalensis, Rhinella arenarum, Rhinella fernandezae, Rhinella schneideri and Melanophryniscus stelzneri. The metaphases were obtained from intestinal and testis cells, using conventional techniques. Twenty metaphasic figures per individual were analyzed and the total length of each chromosome and the length of the four arms were measured. The obtained measurements were processed using Excel 2000 to obtain the average length of the arms p and q, the arm ratio, the centromeric index, the relative chromosome length and the relative arm length. All species showed karyotype 2n = 22, and karyotype formula of 6: 5. Pairs one to six were large, with a relative chromosome length between 18.64–7.59%; pairs seven to eleven were small, with a relative chromosome length between 7.18–2.42%. In all species the chromosome morphology was metacentric or submetacentric. Karyotype and ideograms were made for all species, based on morphometric parameters of the chromosome complement. Finally, discriminant analysis was used to separate the five species analyzed, with a highly significant classification rate of 80% and P < 0.0001. These results agree, in general, with those presented by other authors, however, in M. stelzneri detailed karyological studied have not been made so far, thus this work represents a significant contribution to the karyotypic decryption features of this species and the Rhinellla species from central area of Argentina.
