Description of the embryonic development in the convict cichlid (Amatitlania nigrofasciata)

This paper describes the embryonic development of the convict cichlid from fertilization to hatching, providing a staging table for comparative developmental studies.

Gonadal histology and variation in gonadosomatic index in captive moonfish Mene maculata

This study examines gonadal histology and GSI in captive moonfish to assess spawning-capable status, finding asynchronous ovarian development and male spawning capability at lower GSI values than previously thought.

Constraints on paternal care capacity favor a monogamous mating system in the group-living gobiid fish Trimma marinae

The paper investigates why the gobiid fish Trimma marinae is monogamous despite potential for polygyny, finding that males can only care for up to three clutches, leading females to guard mates to monopolize care.

PEG400 and Tween 80-based simple vehicle for oral delivery of peptide compounds in fish

This paper develops a non-invasive oral delivery vehicle for peptide compounds in fish and demonstrates its use with atosiban.

Social benefits of facial experssion in a cichlid fish: Testing the face concentration hypothesis

This study investigates the social function of facial coloration in cichlid fish, finding it reduces aggression and is controlled by the sympathetic nervous system, independent of mammalian facial expressions.

Chromosomal DNA sequences of the Pacific saury genome: versatile resources for fishery science and comparative biology

This study presents the first whole genome assembly of the Pacific saury using SMRT sequencing, providing resources for fishery science and comparative biology.
