THE LOUSEFISH, Phtheirichthys lineatus (Menzies) , is a slender member of the Echeneidae which is often free-swimming but which also attaches to immotile objects or slow-swimming fishes. It is pantropical, uncommon, and little known biologically. This paper reports on 24 lousefish in the collections of the Bureau of Commercial Fisheries Biological Laboratory in Honolulu. Capture data for these ...

Fishing resources are important generators of income and food for the rural and urban people in the Amazon. The present paper investigates fishing and environmental variables determining fishing production landed in Manaus and evaluates the relative abundance of commercial fishes in the different sub-systems of the Central Amazon basin. Information collected was used to test the new catch index...

In this review, we investigated published data on the occurrence of microplastic in Arctic fish, and suitability species for risk assessment monitoring. As 11 November 2021, found nine studies peer-reviewed literature, one thesis report, confirming fishes from multiple regions. The varied methodology, detection, quantification limitations, reported categories size, shape, chemical identity. All...

Material and methods 105 children with a diagnosis of type I allergy to fish, based on history, specific IgE (sIgE, CAP) to codfish (f3) and skin prick tests (SPT) with commercial fish extracts, are included so far. All children undergo open food challenges (OFC) with canned tuna, fresh swordfish or fresh tuna in order to evaluate whether these fishes are tolerated or not by fish allergic child...

We show that the distributions of both exploited and nonexploited North Sea fishes have responded markedly to recent increases in sea temperature, with nearly two-thirds of species shifting in mean latitude or depth or both over 25 years. For species with northerly or southerly range margins in the North Sea, half have shown boundary shifts with warming, and all but one shifted northward. Speci...

this study was conducted to estimating the amount of non-standard sizes (with lengths less than lm50) fishes of shrimp trawls in the hormozgan province coastal water during shrimp fishing season. sampling was carried out using the tabas otriger commercial trawler during 55 hauls. eight commercially valuable species including pampus argenteus, parastromateus niger, plicofollis dussumieri, saurid...

Since 1993, various public and private institutions have supported the development of a freshwater ornamental industry in Hawai‘i which, based on current success, must be intensive and utilize the latest in culture technologies to remain competitive. Feeding and palatability trials using commercial feeds suggests that very little is understood about the nutritional requirements of the 1500 spec...
