Ichthyoplankton assemblages were investigated during a three-year multidisciplinary project conducted off the coast of south-western Australia. Fish larvae were sampled using replicated oblique bongo net tows along a five-station transect extending from inshore (18m depth) to offshore waters (1000m depth). A total of 148 taxa from 93 teleost families were identified. Larvae of Gobiidae, and Ble...

Effect of feeding on linseed oil (LO)-enriched Artemia was investigated on growth, survival and stress resistance of tiger barb (Puntius tetrazona) larvae. Larvae were fed by LO-enriched (2.5, 5 and 7.5 %) as well as non-enriched Artemia nauplii for 14 d, followed by 14 d feeding on non-enriched Artemia. Fish fed on enriched nauplii showed significant increase in growth performance at both 14th...

During these last 20 years, many studies have focussed on the development of the digestive tract in marine fish larvae. Most of the studies aimed at acquiring knowledge on the optimal form of dietary supply for different nutrients, in order to formulate a compound diet able to totally replace live preys in the fish larvae feeding sequence. Consequently, most of the studies aimed at describing t...

In a mesocosm experiment, we tested whether larval fish show an active behavioural response to hydrodynamic impacts. Exposing I to 3 week old allis shad (Alosa alosa) larvae to a pulsed wave regime, we found that already I week old larvae immediately adapt their microhabitat use and activity patterns at the onset of the wave pulses. The fish larvae in stantaneously increased their activity leve...

Marine fish larvae undergo major functional and morphological changes during the developmental stages and several factors can interfere with the normal development of larvae and affect fry quality. Skeletal malformations, such as spinal malformation—scoliosis, lordosis, coiled vertebral column-, missing or additional fin rays, bending opercle or jaw malformations, are frequently observed in hat...

Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential trace element and both under and over supply of I can inhibit the production of the I containing thyroid hormones. It is unknown whether marine fish larvae require copepod l...

The paradise fish, a small insectivore, coinhabits marshes of Southeast Asia with several predator fish species. Its ability to recognize and avoid harmful fish may depend upon both genetic factors and experience. Here we demonstrate genetic variability between the 20-day-old larvae of two inbred strains of paradise fish (P and S) in predator exploration and avoidance, using predator models. We...
