Ecological Studies of the Pond Smelt, Hypomesus olidns (PALLAS)-II
The scale of pond smelt, Hypomesus olidus (PALLAS), shows no definite annual-ring in such a manner as the scale of salmon or herring. Two different zones, one of which grows in summer and the other in winter, are recognized on the scale of the fish in Lake Kasumigaura by F. MATSUZAKI (1916), while, according to H.

Surf smelt accelerate usage of endogenous energy reserves under climate change.
Surf smelt (Hypomesus pretiosus) are ecologically critical forage fish in the North Pacific ecosystem. As obligate beach spawners, surf smelt embryos are exposed to wide-ranging marine and terrestrial environmental conditions. Despite this fact, very few

Molecular Identification of the Nematode Eustrongylides ignotus in Mandarin Fish, Siniperca chuatsi
ABSTRACT Mandarin fish (Siniperca chuatsi) is a high‐value economic freshwater fish in China; however, the frequent occurrence of diseases threatens its production. To this end, we explored the impact of a nematode parasite newly found in the abdomen of mandarin fish collected from Pudong, Shanghai, China.

The Content of Ca in the Muscle of a Teleost, Hypomesus olidus, in Relation to its Environment
Of the two lakes, Hinuma and Kasumigaura, located close to the coast of the Ibaraki Prefecture, the former is much more subject to invasion of sea-water. The chemical analysis has shown (Table 2) that 0·922 mg. of Ca and 57·31 mg. af Cl are present on average in the water of Lake Hinuma, whereas 0·716 mg. of Ca and 2·178 mg. Cl are present in the water
