The Parque Nacional Sistema Arrecifal Veracruzano (PNSAV) is in the southern Gulf of Mexico and supports an important shrimp fishery based on three species of Dendrobranchiata: the brown shrimp, Penaeus aztecus, the white shrimp, P. setiferus and the pink shrimp, P. duorarum. Objective. Analyze the distribution and abundance of P. aztecus during the mysis stage and determine its relationship with environmental factors in the PNSAV. Methods. We measured temperature, salinity, and dissolved oxygen in situ. The planktonic samples from four transects were collected during cold fronts and rainy weather conditions from 2011 to 2013. Results. In rainy conditions the temperature varied from 27.49 ± 0.46 to 29.98 ± 0.02°C, salinity from 32.18 ± 0.06 to 35.40 ± 0.52, and dissolved oxygen from 3.64 ± 0.13 to 6.18 ± 0.64 mgL-1; during cold fronts the temperature varied from 23.21 ± 0.05 to 25.74 ± 0.37 °C, salinity from 34.59 ± 0.39 to 35.84 ± 0.17, and dissolved oxygen from 4.04 ± 0.06 to 6.02 ± mgL-1. The highest average density with 6,938 ± 326 mysis 100 m−3, was found during rainy season in 2011 in the southern transect nearshore, followed by 3,321 ± 339 mysis 100 m−3 in the offshoresouth-central transect during cold fronts weather conditions in 2013, and 3,056 ± 236 mysis 100 m−3 in the south-central foreshore transect during cold fronts weather condition in 2011. Conclusions. The highest density of P. aztecus during mysis stage was recorded in southward foreshore area from PNSAV, during rainy conditions and related to large values of dissolved oxygen concentrations.","PeriodicalId":50407,"journal":{"name":"Hidrobiologica","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47210427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Guayas cichlid juvenile fish were submitted to 4 feeding treatments: 0%, 4%, 8% and 12% palm cake replacement for 30 days. Several zootechnnical indexes were calculated and analyzed at the end of the experimental culture, as well as the feed proximal composition. Results: The inclusion up to 8% palm cake did not affect the digestibility coefficients of dry matter, gross protein or gross energy. No differences were found in final weight, growth rate, food conversion rate, protein efficiency rate and productive value of the protein among 0, 4 and 8% palm meal content treatments. As the percentage of palm kernel meal in the diets was increased, the food conversion rate decreased. Increasing palm meal in diets decreased costs.

In Colombia, there are no studies on length-dry weight relations at the species level in Anacroneuria nymphs. Goals: The aim of this study was to analyze the morphological characteristic of Anacroneuria marta and A. caraca and to determine possible linear functions that explain the relations between some body dimensions (total length and head width) versus dry weight. Methods: Organisms were collected in areas of rapids and pools of the Gaira River (Sierra Nevada of Santa Marta, Colombia) between October 2014 and March 2015. Nymphs were identified to species level and taxonomic entities were confirmed by a discriminate analysis, using measurements of ten morphological variables. In some organisms dry weight was obtained, which was correlated with length measurements by simple linear regressions. Results: The species A. marta and A. caraca showed statistically significant morphological differences, which confirmed these taxa. The power model was the best adjusted to show the relations of the total length (TL) and the width of the head (WH) with the dry weight (p <0.01). Conclusions: The relationships between body dimensions and dry weight were highly significant, for A. marta the best adjust was with the WH and for A. caraca was with TL, with explanations of 86% and 95% of the variations in biomass, respectively. These equations will serve as a basis for studies of determination of biomass in Plecoptera nymphs.","PeriodicalId":50407,"journal":{"name":"Hidrobiologica","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41937152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Goals: Represent a hydrographic network of a basin employing a graph and study its most representative measures of centrality; as a case study, we considered the hydrologic network of the basins of the department of Quindio. Methods: The theory of networks and the analysis of centrality measures such as degree distribution, PageRank, and eccentricity; also, topological measures such as density and assortativity. Results: The study provided a different approach to research on the properties of river networks. The grade distribution shows a network with input grades of one, two, and three, while the output grade is only one or zero, consistent with a typical mountain basin. Measurements such as density and assortativity showed a low-density network with no defined connection patterns. The centrality of PageRank and eccentricity highlighted the leading causes and the most important rivers according to the way the hydrographic network is connected. Conclusions: The study concluded that by using network theory, we obtained a global vision of the network, understanding its structure and allowing us to visualize which areas of the network are vulnerable. PageRank’s centrality allowed us to identify well-monitored nodes in the network and those that need care; this same distribution highlighted zones in the network that are more prone to contamination. Finally, the eccentricity determined the center of the network (sector of “La Maria”) as one of the network’s most vulnerable areas.","PeriodicalId":50407,"journal":{"name":"Hidrobiologica","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42969874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Zoque rainforest Chimalapas is located in the Isthmus of Tehuantepec, mainly in the municipalities of San Miguel Chimalapa and Santa Maria Chimalapa in the state of Oaxaca, is considered one of the latest well-preserved regions in Mexico, as well as a center of diversity and endemism of flora and fauna. Objective. Develop inventories of the ichthyofauna from Santa Maria Chimalapa rainforest to catalog resources before imminent environmental and human alterations. Methods. Samples were collected using several types of fishing gears in the main rivers and tributaries of the water system. Results. A total of 2,430 fish were collected, corresponding to 38 species, grouped in 31 genera, 19 families, and 12 orders. The families with the greatest species richness were Cichlidae and Poeciliidae with nine and six. Priapella intermedia was the most abundant (30.1% total), followed by Astyanax finitimus (13.3%) and Pseudoxiohophorus bimaculatus (10.3%). Regarding biogeographical aspects of the fish community, a prevalence of neotropical species (91.9%) was observed, two species of Nearctic origin (Ictalurus meridionalis and Ictiobus meridionalis) and four vicarious species (Atherinella sallei, Cathorops cf. kailolae, Eugerres mexicanus, Strongylura hubbsi). 31 species are being evaluated in some risk categories and two are exotic. Conclusions. The ichthyofauna of Santa Maria Chimalapa holds similarities to that of the aquatic bodies present in rainforests of southern Mexico. However, ecological, conservation and anthropogenic impact studies are necessary to establish sustainable conservation strategies.","PeriodicalId":50407,"journal":{"name":"Hidrobiologica","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43647411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kappaphycus alvarezii seaweed is a major commodity of important economic value fishery cultivation that has been developed in many countries. The demand for K. alvarezii seaweed continues to increase because it produces carrageenan which is commonly used as the main raw material in many industrial activities. However, K. alvarezii’s seaweed farming is inseparable from several obstacles. In the seaweed culture system, ice-ice disease is a major obstacle because it can harm the cultivation business. Ice-ice disease causes a decrease in seaweed production. Bacteria play a role in the development of ice-ice disease in seaweed cultivation. Aquatic organisms infected with bacteria indirectly cause damage to tissue. The spread of bacterial diseases in aquatic organisms can occur vertically or horizontally. Goals. This research aims to study the horizontal transmission of ice-ice disease on growth, carrageenan content, and changes in the structure of the K. alvarezii seaweed tissue which were tested in-vivo. Methods. This study uses healthy seaweed thalus weighing 35g and seaweed thallus affected by ice-ice weighing 30g (A), 35g (B), 40g (C) and 45g (D).The parameters observed were morphological changes, carrageenan content and tissue changes with histological analysis. Result. The results of this research indicate that the transmission of ice-ice disease can occur horizontally from thallus affected by ice-ice to healthy thallus. This transmission causes discoloration that shows symptoms of ice-ice attack on healthy seaweed K. alvarezii. This discoloration is accompanied by a decrease in thallus weight. Transmission also causes changes in the structure of the tissue in the form of lysis in the tissue and reduce the content of carrageenan in K. alvarezii seaweed. Conclusions. Based on this research, it can be concluded that the spread of ice-ice disease in seaweed causes color change, weight loss, changes in tissue structure, and reduce the quality of carrageenan.","PeriodicalId":50407,"journal":{"name":"Hidrobiologica","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45846981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interaction between Pterygoplichthys and Florida manatee (Trichechus manatus latirostris) was recorded approximately 13 years ago in Florida, United States. In Mexico, this interaction has not been documented neither in the wild nor in captivity. Until now it was supposed that Pterygoplichthys attach to manatees to forage the epibiota of the skin without causing any damage. However, some behaviour displayed suggests pain, stress, and discomfort when these fish attach to the manatee’s skin. Goals. To determine if the skin wounds found in three captive manatees are associated with the presence of Pterygoplichthys in the facilities where they are housed. Methods. By trawling a large artificial lagoon (AL) for three consecutive days, every six months for two and a half years we decimated the local population of Pterygoplichthys; in the management pool (MP), fish were removed manually. Additionally, we reduced the time individuals spent in the management facilities by releasing them into the AL. Results. Total disappearance of the skin wounds was achieved in three years, due to their decreased interaction with the catfish (both through the reduction of the population of Pterygoplichthys and of the time spent by the manatees in the MP). Conclusions. Injuries were caused by the fact that manatees lived in a small space, without food available for the catfish, which caused an increase in the frequency and aggressiveness of the encounters. Therefore, we recommend creating and implementing strategies to reduce Pterygoplichthys populations in places where manatees inhabit, because in the future the wounds they cause could be a potential threat for the long-term population viability of the endangered Antillean manatee.","PeriodicalId":50407,"journal":{"name":"Hidrobiologica","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75027161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
