“…Study results identified the importance of various rearing parameters and corroborate findings of other researchers (Colesante 1989;Ostrowski 1989;Tsai 1991) working with larval fishes. In particular, success of larval rearing was directly related to the fish's ability to observe and capture food.…”

“…Clear glass aquaria were unsatisfactory for feeding of larvae, while rearing in black tanks provided adequate contrast for successful feeding. Darkening of tank walls was also shown to substantially improve survival of walleye Stizostedion vitreum (Colesante 1989) and dolphin Coryphaena hippurus (Ostrowski 1989) by providing contrasts to prey items. Although initially unsuitable for larvae, clear glass aquaria functioned well for holding 30-d-old white bass in studies to assess feeding behavior.…”

The effects of culture parameters of tank color and feeding regimes were examined on larval white bass Morone chrysops during 1994–1995. Under high surface illumination (998 lux), dark tank walls were essential for effective prey capture. Larvae reared in clear glass aquaria did not grow and had died by day 6 of the study. In contrast, 48.7% of the larvae reared in black‐walled tanks were alive on day 24 and had grown to 17.2 mm total length (TL). In another study, larvae were fed rotifers Brachionus plicatilis and Artemia nauplii in different feeding protocols. In one treatment only rotifers (10/mL) were fed day 1 (4 d post‐hatch), rotifers and Artemia (3/mL) were fed days 2–4, and Artemia fed days 5–15. This protocol produced similar growth (mean size 11.7 mm TL) and survival (mean 30.3%) as slower weaning times from rotifers to Artemia. Juveniles (27‐day‐old, 17.2 mm TL) were converted to a dry crumble diet over a 14‐d period by slow transfer from a combination diet consisting of live Artemia nauplii, frozen adult Artemia, plankton flakes and dry crumbles. Survival offish weaned to the dry diet was 64.5%. Most of the mortalities during the weaning period were fish with uninflated swim bladders which were cannibalized by larger fish. Using the above tank culture techniques, white bass were reared to a mean size of 73.2 mm TL (mean weight 5.8 g) over a 73‐d period. This essentially closes the life cycle of white bass.

Effects of tank colour on larval survival and development of mud crab Scylla serrata (Forskal)

Hatchery culture of mud crabs has not yet achieved commercial viability despite decades of research e¡orts. Further research is therefore needed to better understand larval culture requirements of the crab. Based on anecdotal observations, an experiment was carried out to test whether the background colour of the culture vessel a¡ected larval culture success. Newly hatched larvae of Scylla serrata were reared in culture vessels of ¢ve colours, i.e., black, dark green, maroon, sky blue and white. Larval survival and development were monitored daily until all of them either moulted to the ¢rst crab stage or died. The results showed clear e¡ects of background colour on larval survival. A general tendency of higher larval survival in darker-coloured backgrounds was evident. In particular, overall zoeal survival for larvae reared in black vessels was signi¢cantly higher than those reared in white ones. Background colour also appeared to a¡ect larval development. Larvae reared in darker backgrounds generally had shorter development times and more synchronized moulting. A signi¢cant delay in zoeal development was observed in larvae reared in white vessels. Dark backgrounds possibly facilitated more e⁄cient feeding, reduced settlement of larvae at the bottom of the vessels as well as minimized stress. This result appears to be the ¢rst to demonstrate that background colour can signi¢cantly a¡ect larval survival and development of a crustacean species.
