Biochemical changes in the body components during gonad maturation of the tropical abalone Haliotis varia were investigated using wild collected specimens from the Gulf of Mannar, on the southeast coast of India. The gonadosomatic index (GSI) and the hepatosomatic index (HSI) showed negative correlations throughout the study period as well as during the progression of gonad maturation stages. The highest GSI for both the sexes were in the ripe stages followed by late maturing stages. The HSI ranged from 2.97 to 6.71 in females, and 3.55 to 5.09 in males. Among the biochemical components analysed, lipid and carbohydrate contents showed significant variations in the different tissues of H. varia during the progress of gonad maturation. The highest protein content was in the foot muscle and the lowest was in the digestive gland. Total lipids in the ovary were always higher compared with that of the testis and the values ranged from 12.60 to 26.49%, registering the highest value in the ripe ovary. Gonad carbohydrate content was lower when the lipid content was higher, suggesting the conversion of carbohydrate to lipids. The present study demonstrates the role of nutrient translocation between body parts as an essential part of the reproductive physiology of abalone.

“…In gastropods, the condition index has been used to evaluate the condition of Melongena corona (Zetina et al, 2000) and Bolinus brandaris (Abidli et al, 2012) in relation to the reproductive cycle, since it is deemed a good indicator of the maturity state because of the use of muscle and digestive gland reserves in gametogenesis (Webber and Giese, 1969). Angel-Pérez et al (2007) used a muscle yield index and related it to the gonadal development stages in the bivalve Atrina maura.…”

“…In this regard, it is important to review, test and define the available options for estimating MI. In haliotids, these indices have been used primarily to evaluate the reproductive status of populations (Boolootian et al, 1962;Webber and Giese, 1969;Poore, 1973;Ault, 1985;Capinpin et al, 1998;Counihan et al, 2001;Litaay and De Silva, 2002;Najmudeen and Victor, 2004;Setyono, 2006). The simplest indicator is calculated by dividing the gonad weight by the total weight of the body, and it is commonly used in haliotids (Setyono, 2006) and other gastropods (Zetina et al, 2000;Morais et al, 2003;Abidli et al, 2012).…”

The monitoring on abalone banks has been intensified since the declining of wild global production due to overfishing, disease, environmental changes and poaching. This is to support timely decisions to execute actions for mitigation, prevention, conservation and fisheries production benefits. Eight morphophysiological indices for green abalone, Haliotis fulgens Philippi, 1845 from the Pacific coast of Mexico were evaluated and their performance were elucidated due to their potential as monitoring tools. The Boolootian's gonadic index (GIB) and gonadic area index (GAIA) were informative of complete reproductive cycle, thus are reliable for reproductive patterns monitoring. While gonadic index (GI) and gonadic index of calculated mass (MGI) were suitable indicators only of spawning. The condition index of calculated mass (MCI), foot index of calculated mass (MFI), condition index (CI) and foot index (FI) proved temporal changes of soft tissues condition. The MFI clearly defined the best nutritional status of the green abalone foot between March to August, indicating the time when fishing organizations can get the best yields and highest foot quality at Baja California Peninsula, Mexico.Therefore MFI can be used as cheap and quick information to make decisions on the start-up of fishing operations and abalone condition monitoring.
