“…Water temperature was standardized to 288C, because even slight deviations in temperature are known to affect the time of hatching and duration of swim-up behavior. 5,7 Eggs and larvae were video recorded daily during daylight hours until larvae became free-swimming in the water column. The depth of larvae was noted in single frames selected at 30 min intervals.…”

“…To date, most studies on teleost swimbladders have focused either on the initial inflation of the larval organ [4][5][6][7][8][9][10][11][12] or on the form and function of the adult swimbladder. 3,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] Little attention has been paid to the hydrostatic contribution of the swimbladder during development.…”

From Inflation to Flotation: Contribution of the Swimbladder to Whole-Body Density and Swimming Depth During Development of the Zebrafish (Danio rerio)

Teleost fishes have body tissues that are denser than water, causing them to sink. Many teleosts therefore possess a gas-filled swimbladder that provides lift, allowing fish to attain neutral buoyancy. The importance of the swimbladder as a buoyancy aid during changing body sizes over ontogeny and its role in determining the swimming depth of fish remain unclear. In this study, we have used the zebrafish (Danio rerio) to investigate changes in the size and shape of the swimbladder during development and examine whether these changes affect the hydrostatic contribution of the swimbladder during swimming. Our results showed that swim-up behavior is critical for larvae to first inflate their swimbladder, decrease body density, and attain neutral buoyancy. Following inflation, we found a strong linear correlation between fish volume and swimbladder volume over ontogeny. This trend was supported by measures of the density of zebrafish, which was conserved within a narrow range between 1.00 +/- 0.001 and 0.996 +/- 0.001 g/cm(3) despite an increase in the swimming depth of zebrafish, which occurred upon transition to a double-chambered organ. Finally, we demonstrated that the contribution of the swimbladder keeps the fish within 1.7% of neutral buoyancy throughout larval development.

“…Sudden mass mortality is common in larval rearing and, in this situation, the coefficient of natural mortality is not constant during the rearing period. In the wild and during the early stages of the technological development of larviculture for newly developing species for aquaculture, mortality peaks were observed at specific developmental stages, such as during first feeding, swim bladder inflation, and transition from flexion to metamorphosis [11][12][13][14][15][16][17][18][19][20]. In the finfish larviculture industries for finfish species, such as red sea bream Pagrus major, gilthead sea bream Sparus aurata, Japanese flounder Paralichthys olivaceus, turbot Psetta maxima, and ocellate puffer Takifugu rubripes, no or little mortality occurs at such specific developmental stages.…”

How to determine the appropriate mortality in experimental larval rearing?

et al. 2011

Survival in larval rearing experiments is difficult to estimate due to accidental losses and periodic sampling. The number of sampled fish can be a large proportion of the stocked ones, making it difficult to calculate the overall survival rate and mortality coefficient as this is based on the initial number. Here, a new method of calculating survival is proposed using the mortality coefficient. When the initial stocking density and sampled and final numbers are known, and assuming that mortality coefficient is constant, the final number of fishes can be represented by the formula N t = e -mt (N 0 -RN Sn e mdn ), where t is rearing period (days), N 0 indicates initial number, N t indicates the survival number at t days of rearing, m is the natural mortality coefficient, N Sn is the sampled number in the nth sampling, and dn is the rearing period until removal of the nth sample. The provisional mortality coefficient is calculated from initial and final stocking numbers. Then values for the natural mortality coefficient are substituted into the formula with successive approximation. The coefficient, which most closely approximates the actual survival, is determined as the best fit natural mortality coefficient. Examples of larval experiments are provided to demonstrate the method and show that survival is often underestimated using traditional methods.

The fish early life-stage (FELS) test (OECD Test Guideline 210) is the primary test used internationally to estimate chronic fish toxicity in support of ecological risk assessments and chemical management programs. As part of an on-going effort to develop efficient and cost-effective alternatives to the FELS test, there is a need to identify and describe potential adverse outcome pathways (AOPs) relevant to FELS toxicity. To support this endeavor, we outline and illustrate an overall strategy for discovery and annotation of FELS AOPs. Key events represented by major developmental landmarks were organized into a preliminary conceptual model of fish development. Using swimbladder inflation as an example, a weight-of-evidence-based approach was used to support linkage of key molecular initiating events to adverse phenotypic outcomes and reduced young-of-year survival. Based on an iterative approach, we explored the feasibility of using key events as the foundation for expanding a network of plausible linkages and AOP knowledge and, in the process, identify important knowledge gaps. Given the scope and scale of the task, prioritization of AOP development was recommended and key research objectives were defined relative to factors such as current animal use restrictions in the European Union and increased demands for fish toxicity data in chemical management programs globally. The example and strategy described are intended to guide collective efforts to define FELS-related AOPs and develop resource-efficient predictive assays that address the toxicological domain of the OECD 210 test.
