“…Characteristics of swimming behaviour for each larval developmental stage were based on studies of penaeid prawns in the Gulf of Carpentaria (Rothlisberg, ; Rothlisberg et al ., , ; Condie et al ., ). The time spent by western king prawn larvae prior to settlement i.e., larval duration, is negatively correlated with temperature (Roberts et al ., ). Larval duration periods in the biophysical model were defined by the initial temperatures at spawning (16.9 and 19.9°C) and sourced from Roberts et al .…”

“…Larval duration periods in the biophysical model were defined by the initial temperatures at spawning (16.9 and 19.9°C) and sourced from Roberts et al . (). The duration of each larval stage under each temperature also defined the time period over which larval swimming behaviour was modelled (Table ).…”

“…In marine crustacean fisheries, patterns of larval dispersal, distribution and abundance are major factors regulating recruitment and population size, and are controlled by a combination of factors including the reproductive behaviour of adults, the physiological tolerances and behaviour of larvae, and local hydro‐meteorological processes such as wind‐driven and tidal currents (Rothlisberg et al ., ; Vance and Pendrey, ; Roberts et al ., ). Small decreases in larval recruitment caused by climatic shifts or high exploitation rates on adults may result in large decreases in available fishery biomass in the years following.…”

Data from stock assessment surveys, published research and climate sensors were linked to model the interaction between fishing, physical-oceanographic processes and spatial patterns of larval settlement for western king prawn [Penaeus (Melicertus) latisulcatus]. This information was used to evaluate the trade-off between larval recruitment and catch during fishing periods that demand high prices but coincide with spawning. Total rates of larval settlement were maximized when tidal currents and atmospheric physical-forcing components were coupled with simulations of larval swimming behaviour under average gulf temperatures. Average gulf temperatures sustained longer larval durations and increased larval settlement rates by over 12% compared with warmer gulf conditions simulated under a scenario of global warming. Reproductive data coupled with outputs from the biophysical model identified consistent inter-annual patterns in the areas contributing to larval settlement success. Areas located in the north-east, and central-west of the fishery, consistently contributed to over 40% of all larvae reaching a settlement in each year. Harvest sensitivity analyses indicated that changes in the spatial patterns of preChristmas fishing could lead to improvements in overall rates of the larval settlement while maintaining or improving the levels of catch. Future studies to refine the model inputs relating to physical processes, larval behaviour and mortality rates for P. latisulcatus coupled with surveys of juvenile prawn abundance to ground truth the modelled predictions, would allow stock recruitment relationships to be more closely examined and inform adaptive management of the fishery in the future.

“…For commercially cultured crustacean larvae, the effect of water temperatures on larval growth rates are often incorporated into planning tools, such as degree-hours or degree-days calculations (Kittaka et al 2001(Kittaka et al , 2002Gendron and Ouellet 2009), which are used to determine larval duration under various temperatures from spawning to post-larval metamorphosis (Roberts et al 2012). This allows for the determination of potential feed requirements, which is a particularly important factor in larval culture where forward planning is required for the cultivation of live foods (Stevens 1990).…”

The effects of temperature and salinity on the survival and development of larval Metapenaeus dalli were investigated in two experiments. First, the effects of four temperatures of 22.6, 25.8, 29.4 and 32.6°C on survival and development time were examined from the Nauplius VI to the Mysis I sub-stage. Survival was significantly lower at 32.6°C than at 22.6 and 25.8°C. Development times differed significantly across all temperatures, decreasing linearly with temperature from 161.5 h at 22.6°C to 74.8 h at 29.4°C then decreased slightly to 71.4 h at 32.6°C. Second, the combined effects of three temperatures (21.4, 26.5 and 29.7°C) and three salinities (30, 35 and 40%) on survival and development were quantified over a 48 h period from the Nauplius VI sub-stage. Only salinity was found to influence survival, with peak survival (77.7%) found to occur at the control salinity (*35%). Any increase or decrease in salinity from this value resulted in a decrease in survival, with the lowest salinity tested (30%) having a significantly negative effect on survival (58.4%) when compared to the control. Only temperature was found to influence the rate of development, with significant increases in development index values being recorded as temperature increased. The recommended conditions for optimal survival and development of M. dalli larvae as determined by this study are, therefore, 25.8°C and 35%.

“…But, the temperature can also be effectively manipulated for marine larviculture and it is also possible to accelerate yolk utilisation and larval growth within the temperature ranges that are tolerable to the species. A good deal of investigations has been carried out on the temperature effects in the early larval development and metamorphosis of fish and crustacean embryos and larvae (Ye et al, 1998;Zhang et al, 2006;Roberts et al, 2012). In recent years, cobia Rachycentron canadum (Linnaeus, 1766) is gaining momentum internationally as a lucrative species for sea cage farming due to its fast growth rate and high meat quality.…”

The effect of temperature on the utilisation of yolk-sac and growth in terms of length of the larvae of cobia Rachycentron canadum (Linnaeus, 1766) was investigated. Five temperature levels viz., 29, 30, 31, 32 and 33°C were experimented with the newly hatched larvae for a total duration of 52 hours post-hatch (hph). A clear-cut trend of increase in larval length with increase in temperature was noted. The maximum length recorded was 4.41±0.11 mm at 33°C by the end of the experiment. The yolk-sac volume decreased proportionately with rise in temperature. At the end of 52 hph, the lowest yolk-sac volume was recorded at temperature range of 31 to 33°C. Results of the present study suggest that temperature plays a vital role in the yolk-sac utilisation as well as on growth of cobia larvae.
