“…Similarly, it can also be hypothesized that there is a developmental plasticity among populations of Pacific herring. Although there have been several studies on the genetic population structure of Pacific herring [17,26,27], information on the early development of each population is insufficient to determine if there are similar developmental differences in this species, as might be expected if environmental factors such as temperature greatly differ among regions. Further comparable studies are needed to examine the levels of plasticity in the embryonic development of Pacific herring.…”

The embryonic development and morphology of eggs and newly hatched larvae of the Pacific herring Clupea pallasii were described using laboratory-reared specimens originating from the Miyako Bay stock. The eggs were almost spherical in shape, 1.33-1.46 mm (mean: 1.38 mm) in diameter, and had a thick adherent chorion. They had a segmented pale yellow yolk, no oil globule, and a relatively wide perivitelline space. A subgerminal cavity was observed during the gastrula period, whereas the blastocoel did not appear. Mass hatching occurred by 271 h 45 min after fertilization, and the newly hatched larvae were 7.1-7.7 mm (mean: 7.5 mm) in total length with 53-56 myomeres at 9.6°C. The embryonic development of Pacific herring was substantially similar to that of zebrafish Danio rerio, American shad Alosa sapidissima, as well as Atlantic herring Clupea harengus, and generally followed the basic developmental pattern of teleosts. However, Pacific herring larvae hatched at a more developed stage than some other clupeoids, such as Japanese sardine Sardinops melanostictus, and the progressed developmental stage at hatching could be interpreted as an advanced adaptation.

“…Pacific herring consist of several populations with different spawning grounds, and these populations are genetically isolated from each other [17,26,27]. The fertilized eggs used in the present study were obtained from adults caught in Miyako Bay that are derived from a different population than that examined in previous reports [13,16].…”

“…Parentage assignments in hatchery-reared flounder (P. olivaceus) revealed that almost all the offspring were sired by one of six males, and that half of the 12 spawning females yielded no surviving juveniles at all (Sekino et al, 2003). Although the influence of stocking on population genetic diversity may be trivial compared with that caused by environmental or fishing pressures (Sugaya et al, 2008;Kitada et al, 2009), in some cases, it can be extremely damaging; stocking doubled the number of adult trout (O. mykiss) on spawning grounds in Oregon, United States, but actually cut the total effective population size by two-thirds (Christie et al, 2012b).…”

European lobster stocking requires comprehensive impact assessment to determine fishery benefits

Historically, hatcheries in Europe and North America attempted to contribute to the conservation and enhancement of clawed lobster stocks, but lacked monitoring programmes capable of assessing success. In the 1990s, this perspective was changed by the results of restocking and stock enhancement experiments that inserted microwire tags into hatchery-reared juvenile European lobsters (Homarus gammarus) before release. This allowed recapture in sufficient numbers to prove that lobsters had survived and recruited to the mature fishable stock. However, evidence of recruitment still failed to answer key questions about the ultimate ecological and economic benefits. As a result, a growing number of lobster stocking ventures remain hindered by a lack of clear evidence of the effects of their stocking schemes. This review evaluates these experiments and related studies on other fished species, summarizes key findings, and identifies data and knowledge gaps. Although studies of fitness in cultured lobsters provide some of the most encouraging results from the wider field of hatchery-based stocking, the limitations of physical tagging technology have significantly hindered appraisals of stocking impacts. We lack basic knowledge of lobster ecology and population dynamics, especially among prerecruits, and of the impact of stocking on wild lobster population genetics. We advocate the use of genetic methods to further our understanding of population structure, rearing processes, and stocking success. We also recommend that more focused and comprehensive impact assessments are required to provide a robust endorsement or rejection of stocking as a viable tool for the sustainable management of lobster fisheries.

“…It is therefore necessary to carry out effective fishery management based on reliable ecological information, such as the population structure and the movement of individuals. Pacific herring is distributed in the northern parts of Japan and several populations exist with different morphologies, genetics and spawning areas (Kanno 1989a,b, Kobayashi et al 1990, Sugaya et al 2008. Additionally, each population has independently greatly fluc-tuated in size (Iizuka & Morita 1991, Nagasawa 2001, which possibly affects the fluctuation of the total abundance of the species.…”

In order to examine whether otolith elemental composition of Pacific herring Clupea pallasii reflected spatially specific differences in capture location, we analyzed the elemental compositions in the edge portion of each otolith, which corresponded to the period immediately prior to the capture, as an indicator of the geographic areas in which the outer otolith was deposited. We collected 7 fish groups from 5 coastal sites: Tomamae offshore, Ishikari Bay, Akkeshi Bay, Lake Furen and Miyako Bay along the Japanese coast. Six elemental ratios, Na/Ca, Mg/Ca, K/Ca, Cu/Ca, Sr/Ca and Ba/Ca, were measured in the edge areas of each otolith by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Significant differences were shown in all mean elemental ratios of otoliths among 4 sampling groups in the 2005 year class and among 3 sampling groups in the 2006 year class. The classification accuracy with the jackknife cross-validation using quadratic discriminant function analysis ranged from 80 to 98% and 78 to 100% in the 2005 and 2006 year classes, respectively. Our findings are comparable to those in previous studies and are further evidence that otolith chemistry is a potential tool for identifying the Pacific herring groups with different habitatuse histories and migration patterns.

In order to understand the population dynamics of Pacific herring, it is important to discriminate each ecologically different population and to determine the migration patterns for feeding and spawning in coastal and oceanic habitats.In previous studies, the population structure and the movements of Pacific herring were examined using artificial tags and genetics (Grant & Utter 1984, Kobayashi et al. 1990, Hay et al. 2001, Sugaya et al. 2008. Artificial tagging methods however, can only link a recaptured fish to the geographic area where it was marked. Furthermore, they are impractical for smallsize fishes because of the high rates of mortality during early life stages, and because of the requirement of a large number of tagged individuals to ensure a sufficient number of recaptures. Genetic composition can link fish to their origin populations, but not to the geographic areas where it was distributed. In Pacific herring, therefore, alternative approaches are required for studying the population structure and the movements of individual fish.To date, the chemical compositions of otoliths of teleost fishes have been analyzed to elucidate ecological questions concerning their population structure (Campana et al. 1994, Milton et al. 1997, population connectivity (Gillanders 2002), migration (Limburg 1995, Arai et al. 2004, th...
