Underwater sensors provide one of the possibilities to explore oceans, seas, rivers, fish farms and dams, which all together cover most of our planet's area. Simulators can be helpful to test and discover some possible strategies before implementing these in real underwater sensors. This speeds up the development of research theories so that these can be implemented later. In this context, the ...

Fishborne zoonotic trematodes (FZT) are widespread in Vietnam and Southeast Asia. It is now recognized that the risk of being infected from eating raw fish dishes applies not only to humans, but also to domestic animals (e.g., cats, dogs, and pigs) and fish-eating birds. The role of ducks and chicken, commonly raised on fish farms, as reservoir hosts, however, has not been adequately investigat...

Cage culture plays an important role in achieving higher output and generating more export earnings in Malaysia. However, the cost of fingerlings, feed and labour have increased substantially for cage culture in the coastal areas in Peninsular Malaysia. This paper uses farm level data gathered from Manjung, Perak and Kota Tinggi, Johor to investigate the technical efficiency of brackish water f...

Histopathological studies were conducted on carp fingerlings of Labeo rohita, Catla catla and Cirrhinus cirrhosus during October 2003 to May 2004 from fish farms of Mymensingh area. Monthly samplings were done with 10 fish from each species with the help of seine net. Skin, muscle, gill and liver were collected, processed and stained in Haematoxylin and Eosin. Histologically carp fingerlings of...

Prophylactic antibiotics in the aquaculture and ornamental fish industry are intended to prevent the negative impacts of disease outbreaks. Research in mice and humans suggests that antibiotics may disturb microbiome communities and decrease microbiome-mediated disease resistance, also known as "colonization resistance." If antibiotics impact fish as they do mice and humans, prophylactic admini...

Movement of live animals is a key contributor to disease spread. Farmed Atlantic salmon Salmo salar, rainbow trout Onchorynchus mykiss and brown/sea trout Salmo trutta are initially raised in freshwater (FW) farms; all the salmon and some of the trout are subsequently moved to seawater (SW) farms. Frequently, fish are moved between farms during their FW stage and sometimes during their SW stage...

Abstract Effective utilization of service vessels in sea-based fish farming requires that the are suited to operating environments at farms. This paper presents a methodology for assessing vessel fleet performance when serving network farms with different metocean conditions. Fleet is defined as ability perform operations requested by farms, due time. An optimization simulation approach employe...

Fish farming is promoted in the Republic of Benin to meet demands fish consumption and increase exports neighbouring countries. Targeting farm policy interventions efficiency heterogeneous systems a challenge. Farm type delineation allows for simplifying diversity systems. Multivariate statistical techniques combined with Calinski Harabasz pseudo F statistic bootstrapping were applied determine...

Contamination of fish by fungi and their mycotoxins poses major health concerns to human and animals. Therefore, our study was aimed to investigate Aspergillus flavus (A. flavus) infections and the levels of aflatoxins in Nile tilapia, Oreochromis niloticus (O. niloticus), and fish feed. Samples from O. niloticus and fish feed (n=25 for each) were randomly collected from private fish farms at Q...

This is the report of the occurrence of Lernaea cyprinacea (Linnaeus, 1758) parasitizing the native fish species Steindachnerina insculpta (Fernández-Yépez, 1948). Sixty host specimens were captured in Taquari River, municipality of Taquarituba, São Paulo State, Brazil. Three hosts were infested with L. cyprinacea. The infestation rate was low, with one parasite per host. Proper management shou...
