The Manzala Lagoon in Egypt's Nile ' »elta has become a sediment sink of reduced area and depth, with increased contaminant levels. Loss of much-needed fresh to brackish water reserves and decreased fish catches have serious ramifications. Herein, maps of temporal and regional sediment distributions in Manzala incorporate petrological and statistical analyses of 200 surficial and short core sam...

This study was aimed to investigate the infection of internal parasites Dentex macrophthalmus in Syrian marine coastal waters. A total 409 individuals were collected from Ras Al-Basit north Tartus south following research stations: Al-Basit, different areas along Lattakia beach, Jableh and Tartous, during period January 2019 December 2020.
 The organs (stomach, intestine body cavity) all f...

The European anchovy, Engraulis encrasicolus L. 1758, is one of the most sought-after target species in the northwestern Mediterranean Sea. However, this stock currently consists of small individuals, and landings are reported to have decreased considerably. The main purpose of this study was to assess, for the first time, the interrelationships between size, fecundity, energy reserves and para...

Parasites, causing little apparent damage in feral fish populations, may become causative agents of diseases of great importance in farmed fish, leading to pathological changes, decrease of fitness or reduction of the market value of fish. Despite considerable progress in fish parasitology in the last decades, major gaps still exist in the knowledge of taxonomy, biology, epizootiology and contr...

UNLABELLED BACKGROUND Coral reefs are areas of maximum biodiversity, but the parasites of coral reef fishes, and especially their species richness, are not well known. Over an 8-year period, parasites were collected from 24 species of Lutjanidae, Nemipteridae and Caesionidae off New Caledonia, South Pacific. RESULTS Host-parasite and parasite-host lists are provided, with a total of 207 ho...

Understanding the natural state of coral reefs is paramount to evaluate response these ecosystems local and global human impacts as well management conservation strategies. In French Polynesia, some islands are still pristine or uninhabited, such Tupai atoll. has been with access lagoon prohibited since 2010. However, fishers from nearby often take outer reef slope at Tupai. Our marine biodiver...

It is believed by many that parasites are only as important as the fish they infect. Parasites are ubiquitous, primarily surviving in a dynamic equilibrium with their host(s) and they are often overlooked in fish health assessments. Changes in the environment, both anthropogenic and environmental, can alter the parasite/host equilibrium and cause disease or mortality in fish. Therefore it is im...

An extensive literature review is made of the parasites in marine and freshwater fish in mainland Portugal, the Portuguese archipelagos of the Azores and Madeira, as well as in farmed fish. The host(s) of each parasite species, its location in the host, site of capture of the host, whenever possible, and all the available bibliographic references are described. The economic importance of some p...

The parasitic copepod Gauchergasilus euripedesi (Montú, 1980) Montú & Boxshall, 2002 was described from plankton samples and specimens found in four fish species the estuarine area of Patos Lagoon, state Rio Grande do Sul (RS), Brazil. Later, one different reported parasitized with G. same locality. Species Astyanax Baird Girard, 1854 ( henseli Melo Buckup, 2006 lacustris (Lütken, 1875)...

In the present study, we determine the presence of parasites in fish larvae collected from nearshore waters along the northern and central coast of Chile. The parasites were identified to the lowest possible taxonomic level based on morphological and molecular analyses. The fish sample was composed of 5 574 fish larvae. Of these, 3% harboured only larval ectoparasitic copepods whereas no endopa...
