Along the coastal zone of Nha-Trang, Vietnamese fishermen adopted a special net, Cai ró. This machine (probably coming from China), is used in many countries of Southeast Asia. In Vietnam it is widespread from the north to the south with significant changes. The fixed gear described here is the one generally used in the southern part of Central Vietnam and especially in the province of Nha-Trang.

The species of Scylla found in Vietnam have been studied in relation to the systematic revision made by Estampador, and to establish the distinctive morphological characters of the species. The status of four forms is discussed: Scylla oceanica, Sc. tranquebarica, Sc. serrata, and Sc. serrata var. paramamosain.

Since 1949, The Nha Trang Institute of Oceanography has undertaken an inventory of Vietnamese marine fauna with reference to its collection kept in Nha Trang. The collection contains about 250 species of Brachyura. Rare species of particular interest are described in this note.

This paper deals with the main categories of long-lines from Nha Trang and their Vietnamese names.

Squid fishing is a very important economic activity in many far eastern countries. One of the reasons seems to be an easy process for conservation (dried squid) and high demand from the Chinese market.

On the corals of the Nhatrang bay in Vietnam, eight new species of Hapalocarcinidae have been discovered. This paper gives a brief description.

This note briefly describes four new species of Hapalocarcinidae: Cryptochirus tri, Troglocarcinus edmonsoni, Troglocarcinus sheni, Troglocarcinus stimpsoni

In the genus Tetralia of the family Trapeziinoe, the authors have separated or put in synonymy T. nigrifrons Dana with T. glaberrima Herbst. A study in details of morphologic characteristics of T. nigrifrons has demonstrated that the two species are different and it was an error putting the first in synonymy with the second. But it is no sure that the so-called T. nigrifrons is the species of Dana (1852).

During 1955 researching activities on Hapalocarcinidés in the Nhatrang Bay, the author collected blocks of Montipora verrucosa, genre Hexacoralliaire, and he found an Orthopagurus Harmsi Gordon, never harvested on the coral before. In this paper the author gave a detailed description.

This study provides elements for the revision of the subfamily Eumedoninae. The detailed description of the specimens led to the presence of characters that are common to different genera and many species. A bibliography and a list of genera and species of the subfamily identified in this bibliography is given.

The importance of the variation of Millepora in connection with their habitat is so well known. Boschma (1948) describes some relationships between those variations and some ecological factors. The present paper establishes the taxonomy of Millepora living in the Nhatrang Bay and describes their distribution on the different parts of the coral reef of this bay. Some observations on the variations of some species in relationship with their habitat seem to agree with Boschma's opinion about the action of some ecological factors.

The present paper completes the authors’ studies (1958) on the species of Chlorodopsis of Viet-Nam. It gives observations on the new specimens collected previously and of a new species. It exposes the results of the observations on specimens communicated to the authors by the Museum of Paris, the Indian Museum of Calcutta and the Bishop Museum of Honolulu. These specimens include the syntypes of Chl. melanochira and Chl. Woodmasoni and some samples of another species not yet recorded on the Viet-Nam seashores. The taxonomic position of various species is revised and species maintained by Balss (1938) in the genus Pilodius are included in the genus Chlorodopsis. The authors give a new key to separate all the species of the genus Chlorodopsis.

Few observations on the first male Pleopode of the genus Actea are available. Examining the possibility of using their characteristics for a taxonomic work, the authors expose the obtained data on the subject and describe the Pleopods of 18 species of Actea collected on the Viet-Nam seashores. A tentative to define the different types of Pleopods gives a new argument to consider and recognize the genus Banareia as a distinct genus of Actea.
