“…During Trial 3, temperature averaged 10.0± 0.4°C, 15.0 ±0.8°C, and 19.8 ±1.0°C for treatments 10, 15 and 20°C respectively. The experimental room was lit continuously with overhead fluorescent lighting, as Harzevili et al (2004) demonstrated that burbot larvae can be successfully cultured under continuous light. Ambient air temperature was maintained at 15°C.…”

“…Culture temperatures ranging from 5 to 24°C have been shown to influence growth and survival in larval and juvenile L. lota lota. Warmer temperatures (≤21°C) typically increased growth, whereas colder temperatures, as low as 5°C, increased survival (Donner and Eckmann, 2011;Harzevili et al, 2004;Wolnicki and Kaminski, 2001;Wolnicki et al, 2002). Despite this baseline work, a further understanding of the effect of temperature on growth, survival, and cannibalism, in critical early life history and grow-out stages, is needed, particularly for L. lota maculosa, to aid in the development of burbot aquaculture.…”

“…Following population declines in many parts of their geographic range (Argent et al, 2000;Arndt and Hutchinson, 2000;Keith and Allardi, 1996;Lyle, 1990, 1996;Stapanian et al, 2011), along with prospective commercial aquaculture interests, development of burbot culture has recently begun for both North American Lota lota maculosa and Eurasian burbot Lota lota lota (Harzevili et al, 2003(Harzevili et al, , 2004Jensen et al, 2008;Trebelsi et al, 2011;Wocher et al, 2011;Wolnicki and Kaminski, 2001;Wolnicki et al, 2002;Żarski et al, 2009). Due to the delicate nature and specific biological requirements of burbot early life stages, high mortality remains common, and further refinement of culture methods is needed (Jensen et al, 2008;Wolnicki and Kaminski, 2001).…”

Effects of temperature on the intensive culture performance of larval and juvenile North American burbot (Lota lota maculosa)

et al. 2012

The objective of this study was to determine the effect of temperature on growth and survival of larval and juvenile burbot, Lota lota maculosa. Burbot aquaculture is developing primarily in response to declining wild stocks and a need to restore such populations. Beyond conservation efforts, there is also potential to culture this species commercially. However, many important aspects of burbot culture remain unaddressed. In this study larval and juvenile burbot were reared at three constant water temperatures (10, 15, and 20°C) in an intensive culture setting. Two 30 day trials were conducted during the larval life stage and one 60 day trial during the juvenile life stage. In Trial 1, larval burbot (mean total length ± SD, 6.9 ± 1.0 mm, approximately 65 days post hatch) reared at 20°C grew the fastest, while growth was lowest in the 10°C treatment. Survival was inversely related to temperature, with the lowest average of 6.6% observed in larvae reared at 20°C. The percentage cannibalized was quantified and found to be positively correlated with water temperature, and reached 58.0% in larvae reared at 20°C. In Trial 2, as larvae approached metamorphosis (12.9 ± 1.9 mm, approximately 100 days post hatch), growth was also highest in fish at 20°C and lowest in those at 10°C. At this stage survival was higher in fish at lower temperatures, but the percentage cannibalized appeared independent of temperature, averaging over 50% in fish at all temperatures. In Trial 3, growth of juveniles (59.9 ± 12.4 mm, approximately 205 days post hatch) reared at 15 and 20°C was not significantly different, yet both displayed significantly increased growth relative to juveniles reared at 10°C. Juveniles were fully transitioned to a dry diet, and survival averaged > 93% in all culture temperatures. The percentage cannibalized during this life stage averaged b 5%, and was not affected by temperature. This study demonstrated the importance of water temperature, as it clearly affects culture performance of larval and juvenile burbot. Results from this study have implications for maximizing growth during larval and juvenile life stages of this species, and provide a comparative, empirical framework for establishing conservation, or commercial aquaculture programs for burbot.

“…However, larvae in this study originated from brood fish caught in the natural environment, and females ovulated spontaneously (without hormonal stimulation). In addition, incubation was carried out at the optimum temperature (Wolnicki et al 2002;Harzevili et al 2004). Thus, it can be assumed that in this study, the quality of larvae was affected by other factors, which cannot exclude the biological conditions of this species.…”

“…The published data include a series of studies related to rearing larvae of this species under controlled conditions. They concerned determination of the basic rearing conditions, such as stock density (Wolnicki 2001;Kujawa et al 2002a, b), optimum temperature and photoperiod (Wolnicki et al 2002;Harzevili et al 2004) or the type of the food supplied (Harzevili et al 2003;_ Zarski et al 2009;Wocher et al 2011). Most of the studies concerning early larval development (from the moment of hatching to the moment of exogenous feeding) refer to the Salmonidae and some species of the Cyprinidae, such as the common carp, Cyprinus carpio L., the crucian carp, Carassius carassius (L.) or the chub, Leuciscus cephalus (L.) (Mark et al 1987;El-Finky and Wieser 1988;Laurila and Holopainen 1990;Ç alta 2000), as well as commercially exploited marine species (Williams et al 2004).…”

Dynamics of yolk sac and oil droplet utilization and behavioural aspects of swim bladder inflation in burbot, Lota lota L., larvae during the first days of life, under laboratory conditions

et al. 2013

The study concerns investigation of early larval development of burbot, Lota lota. As part of a two-year study, the first 15 days (until the end of yolk sac resorption) of burbot larvae development under controlled conditions were examined. The aim of the study was to observe the moment of swim bladder inflation and the behavioural aspects of this process, as well as the analysis of yolk and oil droplet resorption and the beginning of exogenous nutrition. It was observed that larvae began to inflate their swim bladder on the 3rd day posthatch. On 5 DPH, none of the larvae without an inflated bladder was able to swim up the distance separating it (10 cm) from the water surface. Since 9 DPH, 50 % of larvae started exogenous feeding, and the absence of yolk was observed on 13 DPH and oil droplet on 14 DPH, while on 15 DPH, 100 % of feeding larvae were observed. The presented results indicate that the analyzed period is critical for burbot, and it is characterized by a high mortality rate (over 60 %). Additionally, the results suggest that, under controlled conditions, the latest moment when burbot larvae should be given exogenous food is 9-10 DPH and until the moment of the swim bladder inflation, larvae should be kept in tanks with a low water depth (up to 10 cm). The data presented in this study could have a significant influence on the efficiency of larvae rearing, both for aquaculture and for restocking purposes.

Early Weaning Effects on Survival, Growth, and Histopathology of Larval Sterlet Acipenser ruthenus

et al. 2020

Weaning of fish is a critical stage during larval rearing and could cause high mortality. Therefore, proper larval weaning period selection is crucial for the success of larviculture. This study aimed to find the effect of weaning on growth performance, histopathological features, and mortality rates in larvae of Sterlet Acipenser ruthenus. The experimental rearing was conducted from 7 to 38 d posthatch (dph) at a mean temperature of 18°C in a recirculating system. The experiment was carried out in three groups (each with three replicates) and placed in nine tanks (22 L) at a density of 10 individuals/L. The diet groups were made up of group C in which larvae were fed with nauplii of brine shrimp Artemia spp., group F7 in which larvae were weaned to dry feed 15 dph, and group F that was fed with dry feed throughout the experimental trial. During 15-38 dph, total wet body weight and total length were lowest in the group fed with formulated feed. Survival rate of larvae in group F7 was 90.45% and 70.05% during 7-14 and 15-22 dph, respectively. On the other hand, the survival rate of larvae fed only Artemia nauplii (group C) or formulated feed (group F) was 86.14% and 70.45% during 7-14 dph and 84.55% and 78.41% during 15-22 dph, respectively. The maximum height of the enterocytic epithelium was found in the individuals in group F7 (mean ± SD = 33.80 ±
