“…This was reflected in the seasonality of our study's prevalence data, as the overall coastwide data and individual bay data showed a peak in H. lynnipositive samples during the early summer through fall, when water temperatures often rise above 26°C (Figure 2). Summer water conditions, which often include high temperatures, high salinity, and low dissolved oxygen, create stressful environments that can limit growth and reduce immune capabilities in marine invertebrates, and regions with prolonged stress due to these conditions may see higher overall disease prevalence (Zein-Eldin and Renaud 1986;Breitburg et al 1997;Martinez et al 1998;Roessig et al 2004;Marcogliese 2008;Vinagre et al 2014;Madeira et al 2016). This is also reflected in our model results: higher temperatures were found to be one of the driving factors of rising disease prevalence throughout the year along the Texas coast for 2019.…”

Shrimp black gill is an emerging disease caused by a parasitic ciliate, Hyalophysa lynni, that attacks gill tissue in white shrimp Litopenaeus setiferus and brown shrimp Farfantepenaeus aztecus and induces an immune response that produces melanized tissue in shrimp gills. This immune response causes necrosis and damage in shrimp gill tissue, which limits shrimp metabolic capability and can lead to high predation mortality among infected individuals. Shrimp black gill was first observed in the southeast Atlantic shrimp fishery in the United States, and this ciliate has been increasing in prevalence in shrimp populations of this region since 2000. The Gulf of Mexico, with its lucrative shrimp fishery and extended warmwater conditions during the year, is a potential region for H. lynni spread. White and brown shrimp were sampled from seven major bays along the Gulf coast of Texas from March to November 2019 and underwent PCR analysis to detect H. lynni presence in gill tissue. From March to November, 65% of the collected shrimp samples tested positive for H. lynni. Samples from all seven bays tested positive for H. lynni, with the upper-coast bays having a significantly higher disease prevalence than lower-coast bays. Both white and brown shrimp samples tested positive for H. lynni; however, white shrimp samples had a significantly higher disease prevalence. Overall, disease prevalence showed a temporal pattern of low prevalence in the spring, peaking during the late fall. Generalized additive mixed models detected a high water temperature and a salinity level of 30‰ or less as significant contributors to high disease prevalence. This study validates the commonality of H. lynni presence in the western Gulf of Mexico, serves as a baseline for future shrimp black gill sampling efforts in this region, and contributes to the understanding and management of potential disease threats to the Texas shrimp fishery.

“…De manera similar, incrementos en las actividades de las enzimas antioxidantes y otros compuestos han sido reportados en especies de poliquetos tales como Nereis (Madeira et al 2016). También, se ha reportado que la actividad de CAT incrementa en las temporadas cálidas en el cangrejo Lithodes santolla (Slechvezov et al 2015).…”

Abstract.-Some antioxidant responses and molecular index of growth (protein:DNA and RNA:DNA) were determined in the polychaete Eurythoe complanata collected from Gulf of Cariaco (Venezuela) during December 2009 (26.03 ± 0.64°C), February (23.96 ± 0.67°C), June (27.82 ± 0.50°C) and October 2010 (29.93 ± 0.37°C). Also, the number of individuals with signs of tissue regeneration was counted. Concomitantly, a bioassay of acclimatization was carried out at 24 and 28°C during 36 days. Muscular tissue was used to determine enzymatic activities of catalase (CAT), glucose-6-P dehydrogenase (G6PDH), glutathione-s-transferase (GST); oxidative damage (TBARS), metallothionein (MT) and thiols (-SH) concentrations. DNA, RNA and proteins (PT) concentrations and their related indexes were determined. During 'no upwelling' season (June and October 2010), when the mean temperature exceeds 28°C, there were increases in CAT, TBARS and DNA. G6PDH, GST, MT and -SH did not vary seasonally or in acclimatizing bioassays. Similarly, in this season a number of individuals collected with new setigers were observed. RNA:DNA and PT:DNA indices demonstrate a continuous growth of the species throughout the year and a significant increase of protein synthesis in low temperatures season (upwelling), respectively. Somatic growth, lipoperoxidative damage and antioxidant capacity in E. complanata are stimulated in seasons of maximal temperature.

También se estimó el número de ejemplares colectados con señales de regeneración tisular. Paralelamente, fue llevado a cabo un bioensayo de aclimatación a 24 y 28°C por un lapso de 36 días. El tejido muscular se usó para determinar las actividades de las enzimas: catalasa (CAT), glucosa-6-P deshidrogenasa (G6PDH), glutatión-S-transferasa (GST); y niveles de daño oxidativo (TBARS), metalotioneínas (MT) y grupos tioles totales (-SH). Además, fueron determinados los niveles de ADN, ARN y proteínas, y sus índices relacionados. En la temporada de no surgencia (junio y octubre 2010), caracterizada por temperaturas promedio que sobrepasan los 28°C, fueron observados incrementos en CAT, TBARS y ADN. Sin embargo, las actividades de G6PDH, GST, MT y -SH no presentaron diferencias estacionales ni variaron en los bioensayos de aclimatación. De igual forma, en la temporada de no surgencia se observó un mayor número de individuos con señales de regeneración. Los índices ARN:ADN y PT:ADN demuestran un crecimiento continuo de la especie durante todo el año y un aumento en la síntesis de proteínas sólo en temporadas de bajas temperaturas (surgencia), respectivamente. La capacidad antioxidante, el daño lipoperoxidativo y el crecimiento...
