Abstract:
... This study provides a first evaluation of different hatchery culture methods for the giant clam Tridacna noae. Three culture methods (intensive, semi-intensive, and extensive) using two tank designs (60 L and 277 L) were successful in producing 30-day old T. noae juveniles. There was no statistically significant interaction between tank design and culture method when considering cumulative surviva ...

Abstract:
... Tagging protocols that result in high tag retention will benefit fisheries professionals who use telemetry data. Ictalurid catfish historically have had very poor telemetry tag retention. Here, we use these difficult-to-tag taxa to address two research objectives. First, we evaluated our field-based internal tagging methodology by quantifying six tag retention metrics using data from 48 acoustical ...

In the framework of a conservation plan for the Italian critically endangered fish (sensu IUCN Red List) Squalius lucumonis, artificial reproduction and larval rearing was carried out for the first time. Wild breeders were collected during reprod ...

Abstract:
... Holothuria polii (Delle Chiaje, 1823) is a common Mediterranean sea cucumber and has recently become a highly exploited target species destined mainly to the Asian markets. Unregulated harvesting is putting the natural stocks at risk, with potential consequences for the benthic communities to which these organisms belong. In response aquaculture, sea ranching and restocking could become solutions ...

Due to the morphological similarity between darkened blind-side skin and normal ocular-side skin, hypermelanosis is regarded as a transition from normal blind-side skin to that of the ocular side. Hypermelanosis appears only in rearing tanks without sand on the bottom, and it ...

Previous research describes low prevalences among individual birds at arrival at the farm (below 30%), and a rapid increase up to 100% within the first week. Our goal was to investigate whether this rapid increase was due to lat ...
