Digenetic trematodes of marine fishes of Ensenada, Baja California, Mexico
… limited to investigate the parasitic fauna of marine fishes from Ensenada, Baja California, and to compile in a single manuscript all data (Host-Parasite list, Parasite-Host list, and distribution of parasites) on digenea previously reported from the Mexican Pacific and the Gulf of …

Digenetic trematodes of marine fishes from the Kuwaiti coast of the Arabian Gulf
<p>D~ring July and August 1978, 165 fishes belonging to 35 species in 19 families were collected from the Kuwaiti coast of the Arabian Gulf and examined for parasites. Nine digenetic trematodes including three new species and two new genera are described: (Hemiuridae) Opisthadena kuwaiti, n.sp. …

Studies in digenetic trematodes of marine fishes from Monterey and Tomales Bays, California
… trematodes collected by the author from fishes of Tomales Bay (including Dillon Beach) during the summers of 1967 and 1968. Also included in this study are several trematodes collected by the late Alden E. Noble (hereinafter referred to as the “Noble Collection”) at Hopkins Marine …

A seascape genetics approach to exploring the phylogeographic response of marine fishes to late Quaternary climate change
… these approaches have only begun to be used in marine ecosystems. This dissertation fills an emerging niche in marine ecology by taking an interdisciplinary seascape genetics approach to investigating the interplay of climate, dispersal and adaptation as shallow-water marine fishes respond to …

Population structure, biochemical adaptation and systematics in temperate marine fishes of the genera Arripis and Chrysophrys (Pisces: Perciformes)
… amount and distribution of genetic variation in fishes of the temperate percoid genera Arripis and Chrysophrys. Available biological and life history data have been reviewed, and indicate that Arripis species are mobile, migratory, pelagic fishes, with planktonic larvae and a comparatively short …

Digenetic trematodes from embiotocid fishes of Tomales and Bodega Bays, California
… present paper deals solely with parasites of marine fishes of the family Enbiotocidae represented in the American Pacific according to Special Publications no. 2, American Fisheries Society, 1960, by 20 species, all of which are marine except the Tule perch, Hysterocarpus traski (Gibbons) from …

Group size affects predation risk and foraging success in Pacific salmon at sea
… and environments, and is particularly common in marine fishes. A rich body of theory outlines ways in which grouping can enhance individual fitness, especially by improved predator avoidance and foraging efficiency. However, such theories are difficult to test in the wild, especially in marine …

Antifreeze Peptides and Glycopeptides in Polar Fishes
… of osmoregulation and reproduction in polar fishes. Polar fishes, like many marine teleosts, have serum osmolalities which are lower than that of sea water. As a result of being hypoosmotic to sea water, marine fishes are faced with a continuous osmotic loss of water. To replace osmotic and …

The effects of habitat on phenotype, growth and fitness in New Zealand triplefin fishes (Family: Tripterygiidae)
… few field studies have examined this process in marine fishes, empirical studies of this nature on marine fishes are important in working towards an understanding of the drivers that promote and maintain diversity in these systems.

Distribution, growth, and transport of larval fishes and implications for population dynamics
The early life stages of marine fishes play a critical role in population dynamics, largely due to their high abundance, high mortality, and ease of transport in ocean currents. This dissertation demonstrates the value of combining larval data, collected in the field and the laboratory, with model …

Life cycle studies on Stephanostomum pacificum, a new species of trematode, from the Pacific Marine Station area
… 1949, 1951, and the winter of 1948-49 at the Marine Station of the College or the Pacific at Dillon Beach, California. Only one previous experimental work has been done on the life cycle of any member of this family. Martin (1939) reported the life cycle of Stephanostomum tenue (Linton) which …

Contribuição à citotaxonomia dos Scorpaeniformes (Osteichthyes - Teleostei): estudos citogenéticos em espécies do litoral do Rio de Janeiro, Brasil
… diversity found in a group of essentially marine fishes, differs from what is found in the majority of the other marine groups studied thus far, in which a great karyotypic stability is observed.

Interrelationships Among Monorchiid Trematodes with Special Emphasis on Some Northwestern Atlantic Genera
… parasitize the digestive tract of estuarine and marine fishes as adults. Compared with other oceans, recent morphological or molecular taxonomic work conducted on monorchiid species from the northwestern Atlantic Ocean has been sparse (Manter, 1931; Overstreet, 1969; Andres et al., 2018; Wee et …

Sensitivity of a LAMP Assay for Detection of the Dinoflagellate Amyloodinium ocellatum in Simulated Field Conditions and Freeze Tolerance of the Parasite
… </em>causes amyloodiniosis in warm water marine fishes. The prolific parasite, which has a direct, three-stage life cycle, is highly infectious and can cause heavy losses in aquaculture. Prevention, biosecurity, and early detection are vital for control. In this work, microscopy and a …
