Fish from lagoons in Northern Luzon, Philippines, have been shown experimentally to be intermediate hosts of Capillaria philippinensis. Eggs ingested by the fish hatch in the intestines and the larvae double in size in 3 weeks. When fed to monkeys, Mongolian gerbils and birds, the larvae develop into adults and reproduce. Fish from the lagoons or purchased from the market were fed to gerbils an...

The growth and development of marine fish larvae fed copepods is superior to those fed rotifers, but the underlying molecular reasons for this are unclear. In the following study we compared the effects of such diets on redox regulation pathways during development of Atlantic cod (Gadus morhua) larvae. Cod larvae were fed a control diet of copepods or the typical rotifer/Artemia diet commonly u...

The anatomy of coralline algae is relatively simple. This, together with high intraspecific variability, reduces characters used as diagnostic criteria in delimiting species in present-day coralline algae to a very few, most of which can be recognized in fossil representatives of this family. Similar taxonomic procedures may thus be used at the species level both in modern and fossil coralline ...

Alterations to the natural hydrologic regime in regulated rivers can disrupt cues that initiate the maturation and spawning of riverine fish, or they can change the conditions which are suitable for the recruitment of larvae into juvenile populations. Observations of fish larvae have the potential to provide insights into the effects of flow regulation, showing whether it has had a greater impa...

The larval stages of malaria vector mosquitoes develop in water pools, feeding mostly on microorganisms and environmental detritus. Richness in the nutrient supply to larvae influences the development and metabolism of larvae and adults. Here, we investigated the effects of larval diet on the development, microbiota content and permissiveness to Plasmodium of Anopheles coluzzii. We tested three...

The majority of marine invertebrates produce dispersive larvae which, in order to complete their life cycles, must attach and metamorphose into benthic forms. This process, collectively referred to as settlement, is often guided by habitat-specific cues. While the sources of such cues are well known, the links between their biological activity, chemical identity, presence and quantification in ...

BACKGROUND Anisakid nematodes are common parasites of fish, mammals, fish-eating birds, and reptiles with a worldwide distribution, causing diseases in human, fish and important economic losses. METHODS A preliminary epidemiological study was carried out on Anisakid nematodes larvae in some commercially important fish species to evaluate the anisakid nematode larvae from greater lizardfish, (...

Aim of the current piece work was to study food composition and feeding intensity Channa striata from Krishna river June, 2019 July 2020. The gut contents were analysed three stations undertaken fish. major components items in fish was: fishes their larvae, crustaceans, insect annelids with semi digested material unidentified items. Fishes are identified as teleost, particularly carps cat larva...

Anisakiasis and Pseudoterranovosis are human diseases caused by the ingestion of live Anisakidae larvae in raw, undercooked or lightly marinated fish. Larvae were collected from one salted cod sold for human consumption in a Sao Paulo market in 2013. One section of one brownish larva was used for molecular analyses. The partial COX2 gene sequence from the larva had a nucleotide identity of 99.8...

Fish larvae, like most adult fish, undulate their bodies to propel themselves. A detailed kinematic study of the larval body wave is a prerequisite to formulate a set of functional requirements that the locomotor system must fulfil to generate the observed swimming kinematics. Lateral displacement and curvature profiles were obtained for zebrafish (Danio rerio) larvae at 2-21 days post-fertilis...
