Ichthyological Research

Top Research Topics at Ichthyological Research?

The scientific interests tackled in Ichthyological Research are Zoology, Anatomy, Ecology, Fishery and Fish fin. Ichthyological Research explores issues in Zoology which can be linked to other research areas like Ecology (disciplines) and Phylogenetic tree. While Anatomy is the focus of the journal, it also provided insights into the studies of Teleostei, Larva and Perciformes.

While Ichthyological Research focused on Larva, it was also able to explore topics like Juvenile and Hatching. Ecology research featured in the journal incorporates concerns from various other topics such as Goby, Rhinogobius and Tributary. It features Fishery research that overlaps with concepts in Bay.

The journal dives deep in exploring the relationship between the study of Fish fin and Dorsum.

Research areas of the most cited articles at Ichthyological Research:

The most cited papers cover a variety of subjects, including Ecology, Zoology, Anatomy, Fishery and Phylogenetic tree. Ecology research in the most cited articles involves the investigation of Goby studies, all of which are linked to disciplines such as Paternal care. The journal articles explore topics in Zoology which can be helpful for research in disciplines like Taxon, Ecology (disciplines) and Teleostei.

What topics the last edition of the journal is best known for?

• Ecology
• Genus
• Fishery

The previous edition focused in particular on these issues:

The journal is organized to address concerns in the fields of Zoology, Anatomy, Ecology (disciplines), Fishery and Genus. Zoology research presented in the journal encompasses a variety of subjects, including Juvenile, Goby, Larva, Predation and Teleostei. Research in Fish fin and the interrelating topic of Perciformes and Meristics were among the subjects of interest in the Anatomy studies discussed in Ichthyological Research.

Ecology (disciplines) research discussed in the journal aim to provide more information in the subject of Ecology. The journal focuses on Fishery but the discussions also offer insight into other areas such as Trout and Japanese eel. In it, Type (biology), Dorsal fin and Key (lock) are investigated in conjunction with one another to address concerns in Genus research.

The most cited articles from the last journal are:

• Contrasting diets of the Japanese eel, Anguilla japonica , in the upper and lower areas of Tsuchikawa-gawa River, Kagoshima, Japan (4 citations)
• A new ponyfish, Deveximentum mekranensis (Teleostei: Leiognathidae), from the Gulf of Oman (3 citations)
• Description of two new species of Bassozetus (Ophidiiformes: Ophidiidae) and a redescription of Bassozetus robustus Smith and Radcliffe 1913 (2 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 14.46% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 60.56% were posted by at least one author from the top 10 institutions publishing in the journal. Another 12.68% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 8.45% of all publications and 18.31% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
