The sea louse is considered an important ectoparasite that affects farmed salmonids around the world. Sea lice control relies heavily on pharmacological treatments in several salmon-producing countries, including Chile. Among options for drug administration, immersion represent majority of antiparasitic strategies used As a topical procedure, do not induce long lasting effect; therefore, re-infestation from neighbouring farms may undermine their efficacy. Synchronization has been proposed as...

The larval fish community in the southern region of California Current (CC) was analyzed to test hypothesis a northward expansion tropical species for summer-fall seasons La Niña (LN) 2010-2011, Blob 2014, and El Niño (EN) 2015-2016. Interannual temperature anomalies (-5 +2°C), as well decreases chlorophyll (68%) zooplankton density (71%), resulted dramatic changes community, such an 82% decline density, unprecedented CC. Tropical richness increased north by 46%, while temperate decreased...
A total of 228 salmonids (90 Oncorhynchus mykiss, 48 kisutch, and 90 Salmo salar) from 8 intensive aquaculture centers in the south Chile were examined for endohelminths parasites between December 2008 May 2009. The body cavities 2 O. mykiss infected by Diphyllobothrium sp. plerocercoids (prevalence: 6.7%, mean intensity: 1.0, abundance: 0.07) Lake Tarahuin hatchery on Chiloé Island.

We analyzed the response of fish larvae assemblages to environmental variables and physical macro- mesoscale processes in Gulf California, during four oceanographic cruises (winter summer 2005 2007). Physical data water column obtained through CTD casts, sea surface temperature, chlorophyll a satellite imagery were used detect structures. Zooplankton samples collected with standard Bongo net tows. Fish responded latitudinal coastal-ocean gradients, related inflow gulf, biological production....

An updated taxonomic list of marine fish larvae from the Gulf California to Colima, Mexico is presented. A total 579 taxa belonging 119 families, 256 genera, and 423 species were recorded. The was compiled using 14 publications on research (1974-2012), identified 315 samples collected with Bongo nets during 10 oceanographic cruises made Bahía de Banderas, Mexico, 2003 2007 (this study). most important families in this study Myctophidae (28.3%), Engraulidae (25.0%), Clupeidae (15.4%)....
The southern Mexican Pacific Ocean presents seasonal changes related to the rainy season and Tehuano winds, which generate mesoscale processes affecting biological productivity marine biodiversity.Size distributions of squid paralarvae collected in this region during (July 2007 May-June 2008) were analyzed relation regional oceanography.Samples through oblique hauls, CTD casts used determine structure water column.Between surveyed periods, there no significant temperature at 10 m, but...
Larval fish composition and abundance were analyzed during February-March (winter) November-December (autumn) of 2005 to investigate which environmental conditions mesoscale oceanographic processes affect the distribution larval assemblages in Gulf California, if these variables are useful delimit specific regions ichthyofaunal distribution.The overall pattern was mostly a latitudinal gradient two faunistic complexes (temperate northern tropical southern complexes) strongly associated with...
The structure of the larval fish assemblage northwestern Pacific coast Mexico is analyzed from zooplankton samples taken between 1998 and 2000 off northern southern Baja California Peninsula. 198 taxa identified reflected faunal complexity reported previously for area. Adult distribution patterns reproductive behavior, added to environmental seasonality bathymetric characteristics coast, explained differences in assemblage.

We recorded seasonal changes in the paralarval cephalopod communities collected off southwestern coast of Baja California Sur, Mexico, during 2003. Simultaneous surface and oblique trawls were carried out with CalCOFI-type nets CTD casts spring autumn 2003 on board R/V Río Suchiate (Secretaría de Marina), at 85 sampling stations (Magdalena Bay to Cape San Lucas). The community predominantly showed tropical affinity both seasons. During autumn, 11 taxa, 2 cosmopolitan one temperate taxon...
An egg mass fragment and one paralarva of the squid Thysanoteuthis rhombus found in Northeastern Tropical Pacific Gulf California, Mexico are first evidence reproduction this species region. The was disintegration process contained 30,360 premature hatchlings (96.2%) 1,192 eggs (3.8%) at different developmental stages. Head chromatophore patterns, buccal crown pigmentation, arm tentacles indexes, other morphological characteristics complement previous descriptions T. paralarvae....
