Embryonic And Larval Development

Early life stages of fishes are critical stages due to their importance in enhancing recruitment. Given the high mortality through the embryonic and larval stages, managers have started investigating factors that impact these stages. Environmental factors, such as water temperature, have been found to play a larger role in early life survival. Climate change predications will be more apparent in northern temperate systems like the Great Lakes. Yellow perch Perca flavescens are an important sport fish in the region whose populations have been declining since the 1980s. Yellow perch recruitment is highly erratic due to the species dependence on spring water temperatures. With warming waters occurring earlier in the seasons, it is unsure how wild yellow perch will adapt. The objective of this study was to determine how variations in temperature regimes during the egg incubation period would impact embryonic and larval development in yellow perch. Four different temperature treatments were used in this study: steady temperature at 16°C, a gradient starting at 12°C increasing by 1-2°C every 3-4 days, a heat shock on day six of 20°C for 16 hours to mimic a heat wave event, and finally, a cold shock on day six of 10°C temperatures for 16 hours to mimic a cold snap event. The results of this study confirm that water temperatures severely impact embryonic development and incubation periods of yellow perch, having a significant impact on the percent of failed larvae at the end of the incubation period (P= 0.0005), with the cold shock affecting the lowest percent of failed larvae (0.8%) while the steady treatment had the highest percent (22.9%). Temperature treatment did have a significant impact on the time it took for larvae to successfully hatch out (P<0.001), but no significant effect on observed mortality and estimated mortality (P= 0.96), percent of surviving larvae (P=0.35), or average growth rate of larvae (P=0.16).This study reveals that yellow perch are better adapted to withstand acute cold shifts in water temperature than acute warming events. Climate change could potentially hinder an already struggling Lake Michigan yellow perch population.

Embryonic And Larval Development

Mature males and females of Leporinus piau (Fowler, 1941) were induced to reproduce through a hypophysation process. Extrusion occurred 12 h or 312 hours-degree after the hypophysation, at a water temperature of 26°C. Fertilized eggs were maintained in incubators at 24°C. Embryonic development, was evaluated using every 10 minutes, fresh egg samples which were analyzed under stereoscopic microscope. The larvae were collected at 24-hour intervals for seven days after hatching, fixed in Bouin's fluid and were submitted to routine histological techniques. The eggs of L. piau were slightly gray, non-adhesive and round-shaped. After 1.5 h the embryo was at the 64-blastomere phase and showed a wide yolk region on the vegetative pole. Within 6.25 h, blastopore closure and the end of gastrula was observed. The differentiation of layers occurred after 7.5 h and hatching after 21 h after fertilization at 24°C or 504 hours-degree. During the first three days of the larvae development there was a gradual yolk sac reduction until its complete absorption on the fourth day, indicating the necessity of exogenous feeding. From the fourth to the seventh day, the final development of the heart, gill arches, swimblader, kidney, hepatopancreas, stomach and intestine were observed. The embryonic and larval development of L. piau were similar to other Anastomidae species.

Parasitic Phase

Between May 1986 and March 1989, the density, breeding cycle, and glochidia production of the unionid clam Anodonta grandis simpsoniana, and the population size and intensity of glochidia infestation of yellow perch, Perca flavescens, were evaluated in Narrow Lake, Alberta. The total number of glochidia produced was compared with the number of glochidia infesting yellow perch, and clam recruitment to age 2 and adulthood was estimated. Clams carried eggs and glochidia between July and, dependent on the prevailing water temperature, May or June of the following year. A total of 2.9 × 106 clams 2 years and older, of which approximately 50% were mature, produced 38.1 × 1012 glochidia in 1987. Of these, 2.6 × 106 (0.007%) glochidia attached to perch, predominantly (>92%) to 1- and 2-year-old fish. Once attached to perch, glochidia had a relatively high survival: 27% to 2 years of age and 9–18% to maturity. These results suggest that the parasitic phase in the life cycle of unionids is most critical.

Air Temperatures

Total yearly growth of female yellow perch, Perca flavescens (Mitchill), in South Bay, Lake Huron, estimated by the distance along the lateral radius from last annulus to scale edge, showed a marked relationship to mean water temperature at a depth of 20 ft. When published data on growth of perch in Lower Red Lake, Minnesota, were compared with mean air temperatures for the period June through September at Redlake, no such relationship could be demonstrated. The reasons for the different results obtained in these and in other studies could not be determined.

The embryonic and larval development of the pipefish Nerophis lumbriciformis is described. The full development sequence lasted 30 d (at 14–15°C), being shortened to 25–26 d at higher temperatures (16–17°C), and hatching occurred throughout a 2–3 d period. Unlike species of the genus Syngnathus, the newly hatched larvae presented a functional mouth apparatus and the yolk sac completely absorbed.

Labrid Species

In March 1997 one male and one female brown wrasse Labrus merula spawned spontaneously in aquaria conditions. Eggs were incubated at ambient temperature, salinity, oxygen and pH. The development of the eggs, yolk-sac larvae and larvae is described and illustrated with particular emphasis on features of practical value for identification of specimens from plankton. The ripe egg of brown wrasse is a typical labrid egg with a mean diameter of 0.93±0.05 mm. The incubation period was 106 h 45 min at a mean temperature of 14.3°C. Newly hatched yolk-sac larvae were 3.8±0.02 mm, while the yolk-sac was resorbed when larvae reached 4.68±0.15 mm in total length. Some characteristics which may be useful for identification are described and compared with some other labrid yolk-sac larvae and larvae. The length of newly hatched yolk-sac larvae of brown wrasse was significantly larger (t-test, P<0.05) than those of the other labrid species, but it is similar to that of Labrus bergylta. During the first 16 d (after resorption of yolk-sac) brown wrasse larvae does not possess a double crescent of melanophores on top of the head, but has a few melanophores on the anal fin which is very similar to the pigmentation of Symphodus (Crenilabrus) melops larvae, although there is a difference in length between them. Larvae older than 16 d have a double crescent of melanophores on the top of the head with melanophores on the anal fin-fold identical to L. bergylta larvae, but the difference in larvae length also exists.
