Paschoal LRP, Zara FJ. Assessing the ovarian development of Macrobrachium amazonicum (Heller, 1862) phenotypes by means of an integrative analysis. Tissue Cell 2023; 84:102166. [PMID: 37499319 DOI: 10.1016/j.tice.2023.102166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 06/14/2023] [Accepted: 07/13/2023] [Indexed: 07/29/2023]
Abstract
Macrobrachium amazonicum is a species of economic interest with a wide distribution in the Americas and high morphological and reproductive variability. Three phenotypes can be observed in this species: i) large-size amphidromous, ii) large-size and iii) small-size hololimnetic prawns. In the present work, the morphological, histochemical and ultrastructural aspects of ovarian development in the three phenotypes were comparatively analyzed. In addition, the interaction between the ovary and the hepatopancreas was investigated in these phenotypes through the use of gonadosomatic (GSI) and hepatosomatic (HSI) indices. Despite the morphological differences and different reproductive strategies adopted by the females, the macroscopic, histochemical and ultrastructural patterns of ovarian development showed no differences between the phenotypes. The ovaries were macroscopically classified into five stages of development (I to V). In early stages (I and II), the ovaries are full of oogonia, previtellogenic oocytes and oocytes in primary or endogenous vitellogenesis. At these stages, the rough endoplasmic reticulum (RER) produces a granular electron-dense material and sends it to the Golgi apparatus, where it will be modified, compacted and transformed into immature yolk granules. From stage III, secondary or exogenous vitellogenesis begins (with no interruption of endogenous vitellogenesis), where follicular cells nourish the oocytes and extracellular material is absorbed by endocytic vesicles, which fuse with immature yolk granules (forming mature granules) or with existing mature yolk granules. In stages IV and V, secondary vitellogenesis continues and mature yolk granules progressively occupy the cytoplasm. In M. amazonicum, the patterns of increase in oocyte diameter are quite similar between phenotypes, being greater in the small-size phenotype. This is related to the formation of larger oocytes/eggs and the production of large lipid reserves for their larvae. Changes in GSI and HSI during ovarian development show strong similarity between phenotypes, supporting the results obtained by histology and ultrastructure. Females in stages III and IV mobilize hepatopancreas reserves for ovarian maturation, which justifies the higher HSI values recorded in these stages. On the other hand, females in stage V show higher GSI and lower HSI values, indicating a mobilization of resources for the end of ovarian development as the females are ready to spawn.

Behavioral and morphological aspects of the reproductive system. ARTHROPOD STRUCTURE & DEVELOPMENT 2021; 63:101060.

Abstract
We evaluated the mating behavior of Potimirim potimirim in the laboratory based on the assumption that this caridean might be hermaphroditic. We also performed histology and scanning electron microscopy analyses of the reproductive system of females, males, and differentiated individuals. The mating experiments produced three behavioral stages, namely, interaction, lateral positioning, and copulation (which did not necessarily occur in this sequence). The hypothesis of a random pure searching mating was corroborated by the lack of male courtship, postcopulatory guarding, and the high aggregation of individuals. Three macroscopic ovarian stages were recorded in adult females: rudimentary, developing and mature. Secondary vitellogenesis begins at the developing stage, producing mature yolk. The male reproductive system is formed by testes and the vasa deferentia (VD), that is divided into three regions: proximal, middle, and distal. The proximal VD has a typhlosole that produces a thin layer of type II secretion around the central spermatozoa mass immersed in a type I secretion. External and adherent type III secretion is produced from the MVD to DVD, and both compound the primordial spermatophore. Potimirim potimirim has a gonochoric reproductive system and mating behavior and its sexual system does not fit into any of the previously described protandric systems.

Abstract
The peppermint shrimp Lysmata vittata (Caridea: Hippolytidae) is
a marine caridean shrimp popular in marine aquarium trade. The species is known
to display the sexual system of protandric simultaneous hermaphrodite. In this
study, based on captive bred specimens, the complete ontogenetic gonad
development of L. vittata was studied both
morphologically and histologically, from newly settled juveniles until they
reached euhermaphrodite phase. It was found that in all specimens examined
(carapace length: 1.8–8.5 mm), including the newly settled juveniles, possessed
ovotestes, which comprised of an anterior ovarian and a posterior testicular
part. Based on both morphological (e.g., size, color and shape) and histological
features (e.g., oogenesis and spermatogenesis), four gonadal development stages
were defined and described for L. vittata.
From Stage I to III, the testicular part of the gonad became gradually mature
but the ovarian part was still immature, which is defined as the male phase. At
the male phase, cincinulli (5–8 hooks) presented at the tips of the appendix
interna on the first pair of pleopods while appendices masculinae (AM), in a
form of a stick structure with spines, presented at the inner edge of the
appendix interna (AI) on the second pair of pleopods. At Stage IV, both the
testicular part and the ovarian part were mature and hence is defined as
euhermaphrodite phase. At the euhermaphrodite phase, most individuals lacked
cincinulli and appendices masculinae on the first and second pair of pleopods
respectively. This is the first time that complete ontogenetic gonadal and
external sexual character development have been described and staged for a
species from the genus Lysmata from newly settled juveniles to
euhermaphrodite phase.

A unified scale for female reproductive stages in the Norway lobster (Nephrops norvegicus): Evidence from macroscopic and microscopic characterization. J Morphol 2018; 279:1700-1715. [PMID: 30378702 DOI: 10.1002/jmor.20852] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2018] [Revised: 05/29/2018] [Accepted: 06/03/2018] [Indexed: 11/09/2022]
Abstract
Knowledge of the reproductive cycle in exploited species is important for a sustainable management of fisheries. Standardized scales to assess maturity stages are a fundamental tool to understand the demographic composition of exploited populations. Staging scales for female Norway lobster, Nephrops norvegicus, have been subject to a series of changes, and multiple inconsistent scales are in use in different fisheries regions. A unified, evidence-based scale has not previously been established. We reviewed previous staging scales for the female ovary maturation and propose a revised scale based on the correlation between macroscopic and microscopic ovary characteristics. To provide better-informed tools for future stock assessment, female stages were characterized through external observation on ovary color and size, and the progress of vitellogenesis. This study clarifies several biological phases that were conflated in previous scales. First, we demonstrate how to distinguish between immature ovaries in juvenile females versus the earliest ovary maturation stage in adults. Second, the new scale differentiates between "mottled" ovaries seen in two separate biological stages: the spent ovaries that undergo partial resorption in berried females, versus ovaries of females which failed to spawn and undergo full resorption. To ensure consistent application, colors are assessed relative to international standards (RAL/Pantone). This new, practical staging scheme clarifies the correlation between microscopic characteristics and macroscopically observable details in ovary maturation. Adoption of this unified staging scale will improve maturity analyses, help to identify stocks with potentially reduced reproductive capacity, and facilitate broad-scale comparisons.

Acta Histochem 2017; 119:769-777. [PMID: 28988659 DOI: 10.1016/j.acthis.2017.09.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2017] [Revised: 08/15/2017] [Accepted: 09/05/2017] [Indexed: 11/17/2022]
Abstract
Callichirus major, popularly known as ghost shrimp, is a species of great importance in the fishing industry, because of its use as live bait. This study aimed to describe the different stages of the developing ovaries in C. major. Shrimps were collected along the Corujão beach, Piuma, Brazil (20°50'41.6"S 40°44'15.7"W), and the gonads were dissected for histological and histochemical analysis. The ovary consists of two elongated filaments covered by a connective tissue that divides the organ into lobules, where somatic and germ cells are found. It was possible to classify five types of germ cells: Oogonia (Oog), previtellogenic oocyte (Oc1), early vitellogenic oocyte (Oc2), late vitellogenic oocyte (Oc3) and mature oocyte (Oc4) based on their vitellogenic stage, cytoplasmic, nuclear and morphometric characteristics. The histochemical analysis demonstrated an intense reaction for proteins and polysaccharides in peripheral cytoplasm of Oc3 comparing to others cell types. According to size, volume, color intensity and distribution of oocyte types the gonads were classified into: immature, developing, developed and spent, being in females at this last stage, observed empty follicles and oocytes in reabsorption process. During oogenesis was observed a gradual increase in cytoplasmic acidophilia due to accumulation of yolk granules and the intense histochemical reaction in periphery of Oc3, which indicate the beginning of an extravitellogenic source of nutrients. Based on the microscopic analysis of the vitellogenesis, shrimp C. major showed the initial short phase of oocyte growth following with a fast vitellogenic cycle.
